Baseball slang 101: A guide to talking like you’re in an MLB clubhouse
So you want to talk like a baseball person? Then you’ll have to curse a lot.
At least, that’s how Pat Murphy, the Milwaukee Brewers’ manager, explained it to his boss’ young son. As long as you’re wearing a baseball glove, Murphy told Tyler Arnold — the son of Brewers’ general manager Matt Arnold — you can use whatever words you hear in the clubhouse. That didn’t go over too well at home.
“A lot of it’s not very PG,” said Seth Lugo, a Kansas City Royals pitcher, who shares kid-friendly stuff with his own son.
“He wants to hit balls in the backyard, so he’ll hit ’em and I’ll say ‘steak dinner!’” Lugo said. “First time I told him that he’s like, ‘What is that?’ And I’m like, ‘RBI… rib-eye… steak dinner.’ So now whenever he’s hitting balls, he’s going, ‘Steak dinner!’”
The thing about baseball slang, though, is that a lot of it applies only to baseball. When a teammate strikes out a hitter with a fastball, for example, you might salute it by yelling “doors!” — as in, he blew the doors off that guy. Or there’s this, from New York Mets reliever Adam Ottavino, also for a strikeout.
“Go sit in the truck,” Ottavino said. “It’s just one of those things where your dad would get mad at you and tell you to go sit in the car. Like, ‘Go sit in the truck and think about what you just did.’ There’s probably something like that for almost every situation in baseball.”
Cheese. Uncle Charlie. Walk-off. Golden Sombrero. Platinum Sombrero. While narrow in scope, the baseball ecosystem has its own vast and peculiar vocabulary. Enough to fill a dictionary, in fact.
But what about those distinctive baseball expressions that could also apply to the larger world, where they’d sound laughably out of place? If you’re in the game, you know the feeling.
“The thing that comes to mind for me is the scouting scale, 20 to 80,” Arnold said, referring to the Branch Rickey grading system — still widely known — in which 20 is the low and 80 the high.
“So I’ll be like, ‘That’s a 70 sandwich’ or ‘That’s a 35 restaurant’ – like, it’ll play, but not a regular. And no one understands what we’re talking about. But when you’re in baseball, you’re like, ‘I get it.’ You know what a 35 is.”
One baseball person might ask another, “How hard is he throwing?” or “What was the velo on that pitch?” And yet baseball people would never, ever ask, “How fast was that pitch?”
They know this makes no sense.
“You wouldn’t say ‘What was your velo on your drive home?’” said Derek Falvey, the Minnesota Twins’ president of baseball operations. “You’d say, ‘How fast were you going?’ But if someone says, ‘How fast was that pitch?’, you know they’re not around baseball very much.”
Well, there are a couple of ways to change that. You could spend the bulk of your life embedded in dugouts, clubhouses, front offices or press boxes. Or you could read our back-to-school primer, with 20 tips on how to sound like a big leaguer in everyday life.

“That suit looks good, I think I’ll wear it to the wedding.”
Baseball meaning: v. – to absorb a humiliation for the good of the team
“It was already 6-0, but the bullpen was worn out so the starter had to stay in and wear it.”

Lions pull off thrilling overtime win over Rams behind breakout game from Jameson Williams
There was only one way to end the first full Sunday of NFL games – overtime.
The Detroit Lions got the season started off right with a 26-20 win over the Los Angeles Rams in a thrilling finish.
Detroit got the ball first in the extra period and didn’t allow Los Angeles to have an offensive play. Two run plays set the tone for the drive. Khalif Raymond picked up a first down on the first jet sweep carry. Then, David Montgomery took the ball 21 yards and into Rams territory.
Jared Goff then threw a pass to Jahmyr Gibbs for a 10-yaad gain. At this point, the Lions could smell the end zone.
Montgomery had a few more carries and eventually found the end zone for the score. He finished with 91 rushing yards. Gibbs added 40 yards on the ground and a touchdown.
Goff was 18-for-28 with 217 passing yards, a touchdown pass and an interception.
The Lions had a pretty commanding lead early in the third quarter. Goff threw a 52-yard touchdown pass to Jameson Williams with 10:29 left in the quarter to put Detroit up 17-3.
TOM BRADY REVEALS WHAT HE’S ‘VERY HAPPY ABOUT’ AFTER CALLING FIRST NFL GAME
It was at that moment the Rams needed to dig deep and get back into the game.
Stafford led the Rams on an 11-play, 70-yard drive that ended with a Kyren Williams touchdown to cut the deficit down to seven points. Rams kicker Joshua Karty added a 26-yard field goal and then Stafford found Cooper Kupp for a 9-yard touchdown.
In the Lions’ final drive, Goff got Detroit back to within field-goal range and Jake Bates hit a 32-yarder to tie the game. It was 20-20 when the game went into overtime.
Williams finished with five catches for 121 yards.
Stafford had a terrific game for the Rams. He showed up more for Los Angeles in the second half than he did in the first half. He ended the game with 317 passing yards, a touchdown pass and an interception.
The Rams’ offense was hurt early in the game when Puka Nacua left the game with a knee injury. He did not return.
Kupp had to step up in his absence. He had 14 catches on 21 targets for 110 yards and a touchdown. Tyler Johnson had five catches for 79 yards.

Rams defense can't stop Jared Goff and Lions late in overtime loss
A remade Rams defense played the Detroit Lions tough through four quarters on Sunday night.
But they could not stop the Lions in overtime.
Jared Goff drove his team 70 yards in eight plays and David Montgomery scored on a one-yard touchdown to send the Rams to a 26-20 defeat before 66,530 at Ford Field.
Rams quarterback Matthew Stafford passed for a touchdown, running back Kyren Williams scored a touchdown and veteran safety John Johnson III had a key interception, but that was not enough.
It was another heartbreaking loss for the Rams and Stafford, who lost here, 24-23, last January in an NFC wild-card game.
Stafford, who played his first 12 seasons in Detroit, completed 34 of 49 passes for 317 yards and touchdown, with an interception.
But Goff, for whom Stafford was traded in 2021, outdueled him again, completing 18 of 28 passes for 217 yards.
It was a costly defeat for the Rams in more ways than one.
Wide receiver Puka Nacua and offensive lineman Steve Avila left the game because of knee injuries, offensive lineman Joe Noteboom an ankle injury.
The rash of injuries in the opener harked to 2022, when the defending Super Bowl-champion Rams lost several offensive linemen during a season-opening rout by the Buffalo Bills, a
The Rams trailed, 10-3 at halftime, and the Lions extended their lead early in the third quarter on Goff’s 52-yard touchdown pass to receiver Jameson Williams, who got behind Rams cornerback Tre’Davious for the long scoring play.
Rams running back Kyren Williams pulled the Rams to within 17-10 late in the quarter with a two-yard touchdown run. Stafford’s 14-yard pass to receiver Demarcus Robinson on a fourth-and-three play at the Lions’ 29 was the key play in the 70-yard drive.
Stafford and receiver Tyler Johnson connected for a long pass play that set up an apparent touchdown run by rookie receiver Jordan Whittington. But a holding penalty nullified the play and the Rams had to settle for a field goal that pulled them to within 17-13.
Johnson’s interception set up an 80-yard scoring drive that Stafford capped with a nine-yard touchdown pass to Kupp for a 20-17 lead with less than five minutes remaining.
The Rams had an opportunity to seal the victory when they got the ball back with just over four minutes left. But they were forced to punt, and the Lions kicked a field goal with 17 seconds left to force the game to overtime.

Notre Dame’s stunning upset loss to NIU: What went wrong for Irish? Are Playoff hopes gone?
By Pete Sampson, Stewart Mandel and Justin Williams
No. 5 Notre Dame suffered a shocking upset against Northern Illinois, losing 16-14 on Saturday in South Bend after missing a 62-yard field goal on the last play.
The Irish were 28.5-point favorites, per BetMGM, and it’s the first time NIU has beaten a top-10 team in school history.
After Notre Dame quarterback Riley Leonard threw an interception with 5:55 left while holding a 14-13 lead, NIU drove 31 yards in 11 plays and got a 35-yard field goal from Kanon Woodill to take the lead with 31 seconds left. The Huskies had converted one fourth down en route to the field goal but were denied another first down by a questionable spot a few plays later, forcing them to attempt the go-ahead field goal earlier than hoped. Notre Dame completed a pass into NIU territory in the final seconds before its long field goal attempt was denied.
The loss comes one week after Notre Dame seemingly made an early College Football Playoff statement with a 23-13 win at Texas A&M. Now, the Irish are left picking up the pieces following a loss to a MAC team, the second time the Fighting Irish have lost at home to an opponent from the Group of 5 under third-year coach Marcus Freeman.
“Disappointing. It’s our job as coaches to make sure these guys are ready to go,” Freeman said afterward. “I’ve always said performance is a reflection of preparation.”
This is what it’s all about.

What happened to Notre Dame?
Notre Dame can check its College Football Playoff hopes, which fell to 34 percent immediately after Week 2 in The Athletic’s model from 73 percent — and may look far bleaker than that.
Even if the Irish had held on against Northern Illinois, Notre Dame looked like a shell of itself after last weekend’s statement win at Texas A&M. It all left Freeman exposed at the start of his third season, which looked like a make year last weekend and a break year on Saturday.
For Notre Dame, the loss deflates a season that was supposed to define Freeman’s tenure, one way or another. Now he’s left to explain another loss to a Group of 5 team, after previously losing to Marshall in 2022. Back then, Freeman had the benefit of time. He was supposed to learn on the job as a first-time head coach. This is different. Freeman was supposed to have matured in the job entering his third year, both in roster construction and staff assembly.
Retaining defensive coordinator Al Golden and hiring offensive coordinator Mike Denbrock felt like master strokes. Plucking Leonard out of the portal from Duke felt like genius move. Instead, Notre Dame is nearly drowning in questions two weeks into the season. — Sampson

Notre Dame suffers stunning upset to NIU: How did everything go so wrong for Irish?
Notre Dame’s offense deflates Playoff hopes
For the second time in as many weeks, Notre Dame’s new-look offense failed to inspire — and this time it cost them the game. Last week against Texas A&M, the Irish admirably rode a couple of long touchdown runs to victory in College Station, which was enough against an even worse A&M offense. But Saturday’s loss to Northern Illinois put the spotlight squarely on those struggles, particularly in the passing game, as Leonard finished 20-for-32 for 163 yards, zero touchdowns and two interceptions, after throwing for just 158 yards last week. In total, NIU outgained Notre Dame 388 to 286.
Freeman hired Denbrock this offseason specifically to address these concerns, bringing in a veteran play-caller and someone he worked alongside for a number of years while they were both coordinators at Cincinnati. At LSU last season, Denbrock led the most potent offense in the country in terms of points per game and yards per play, and produced a Heisman-winning QB in the process. Neither that explosiveness nor the familiarity has manifested for Notre Dame yet in 2024, but it needs to if the Irish still have any hopes of reaching the Playoff. And after Saturday, they may not. — Williams
NIU scores biggest win in program history
NIU had its moments over the year — beating No. 21 Alabama in 2003, going to the Orange Bowl in 2012 and producing Heisman finalist Jordan Lynch in 2013 – but beating a top-five Notre Dame team in South Bend is without question the biggest win in program history.
The previous highest-ranked win for the Huskies came against No. 15 Maryland on Aug. 28, 2003. It’s also the highest-ranked opponent a MAC team has ever beaten. The last time the MAC had a top-10 win was on Sept. 20, 2003, when it had two, plus NIU’s win over Alabama on the same day.
Sixth-year head coach and former NIU star running back Thomas Hammock led the Huskies to 2021 MAC championship game, but the team had been just 11-15 since then. NIU tied for third in the MAC’s preseason poll, and we’ll see if this upset becomes the prelude to another championship run.
Remember: The highest-ranked Group of 5 conference champion makes the Playoff. — Mandel

Notre Dame has a quarterback problem
For all the praise directed at Leonard during the past nine months, Saturday was a reminder that little of it has been directed toward his right arm. Leonard has leadership qualities and run-game skills, but he has been a developmental passer two games into his Notre Dame career. For a quarterback with designs on playing at the next level, that must improve before the end of this season.
Leonard didn’t complete a pass of at least 20 yards against Northern Illinois and barely attempted any. He often looked hesitant reading the Northern Illinois defense and was picked off in the first half on a late throw over the middle to Jaden Greathouse. He was later picked off in NIU territory, setting up the Huskies’ winning drive.
The best of Leonard remains his rushing ability, which was ominously obvious on Notre Dame’s touchdown drive to open the game. Leonard had five rushing attempts during that drive, including the touchdown. It was as good as the Duke transfer looked in the game.
During training camp, Denbrock referenced how it took Jayden Daniels until his second season at LSU to master his offense, often not trusting his wideouts during that first fall. Leonard doesn’t have that kind of time. — Sampson
Why Notre Dame’s defense struggled
Notre Dame’s defense staged a professional performance last weekend at Texas A&M. The Irish didn’t allow a run of 10 yards or more. They didn’t allow a pass beyond 20 yards. They gave up just 13 points.
That all fell apart against Northern Illinois as the Huskies worked misdirection into the game plan at the expense of the younger Irish linebackers. Ethan Hampton hit running backs Antario Brown for an 83-yard touchdown in the first quarter with Kyngstonn Viliamu-Asa in coverage. Brown put up a 43-yard reception later in the quarter. The Huskies also posted a 28-yard run.

— #MACtion (@MACSports) September 7, 2024
It’s hard to square how Notre Dame’s younger linebackers — Viliamu-Asa, Drayk Bowen, Jaylen Sneed and Jaiden Ausberry — could regress so much in a each, although Ausberry made a big third-down stop and a fourth-down pass break-up in the second half. Whatever the reason, Golden and linebackers coach Max Bullough have a problem to solve heading toward next week’s game against Purdue.
Jack Kiser might be a reliable captain of the defense, but he needs help. — Sampson
“We’re 1-1. We have to accept that fact. But we have a long season ahead of us.” – Xavier Watts

What’s next?
Notre Dame resumes its in-state rivalry against Purdue with a trip to West Lafayette next Saturday, followed by home games against Miami (OH) and Louisville before an Oct. 5 idle date.
NIU has an off week to celebrate its monumental win in South Bend before hosting Buffalo on Sept. 21 and visiting NC State for another chance at a Power 4 upset on Sept. 28.
