Let’s analyze FanDuel Sportsbook’s lines around the Mariners vs. Orioles odds and make our expert MLB picks and predictions for the best bets.
Season series: Orioles lead 1-0
The Mariners lost to the Orioles to open the series 9-2 Friday, failing to cover as run-line underdogs. They closed +117 on the moneyline. Seattle has won 3 of its last 5 games yet is just 6-8 over its last 14. The Mariners have struggled offensively, scoring just 2 runs in 2 of their last 3 games.
The Orioles have won 2 straight and 5 of their last 7. However, they are just 1-4 against the spread (ATS) in their last 5 games (23-19 ATS on the season). Baltimore is the 7th-best home team in MLB with a 16-9 record.
Mariners at Orioles projected starters
RHP Luis Castillo vs. TBD
Castillo (4-5, 3.31 ERA) makes his 10th start. He has a 1.12 WHIP, 1.8 BB/9 and 10.6 K/9 through 54 1/3 IP.
- Last start: Win, 6 IP, 2 ER, 7 H, 0 BB, 8 K in an 8-4 home win over the Oakland A’s Friday

While the Orioles have yet to announce a starter, 30-year-old Cole Irvin seems on deck and could’ve started Friday. It was noted he didn’t start due to injury, so he’s a likely option for Baltimore.
- Irvin 2024 home stats: 2-1, 3.22 ERA (22 1/3 IP, 8 ER), 1.12 WHIP in 4 starts

Mariners at Orioles picks and predictions
Prediction
Marines 5, Orioles 3
Moneyline
BET MARINERS (-106).
Castillo struggled to start the season, but he has been on fire over the last month. He has pitched 32 2/3 innings and has 6 ER. During that span, in his starts, the Mariners have road wins over the Rockies and Rangers and home wins over the Braves and A’s. Seattle is 4-1 over his last 5 starts.
It has also scored at least 4 runs in 3 of its last 5, so it has sustained some success offensively. The Orioles blasted the Mariners in the first game and are 16-11 after a win. Seattle is 13-7 after a loss. Considering those trends and Seattle’s pitching edge, take MARINERS (-106).
Run line/Against the spread
PASS.
There’s no value here. The Mariners are too risky as run-line favorites, while the Orioles are far too expensive as run-line underdogs. Ultimately, the moneyline has the only team-specific value here.
Over/Under
LEAN OVER 7.5 (-110).
Both teams have had success on the Over as of late. The Mariners are 8-2 O/U in their last 10 games and have scored at least 6 runs in 4 of those.
The Orioles have tallied at least 7 in 3 of their last 9 and are 5-4 O/U in that span. Baltimore is 21-17-3 O/U on the season. The recent trends point to the Over, so back OVER 7.5 (-110).
