Four years later, the memory remains uncomfortably fresh.

The last time the Dodgers tried to defend a World Series title, they racked up 106 victories. They matched the best winning percentage in the franchise’s Los Angeles history. They had seven All-Stars and three Cy Young vote-getters.

And it still wasn’t enough to win them the National League West.

The San Francisco Giants, the Dodgers still well remember, won 107 games in the 2021 season, marking the only time in the last dozen years someone else has claimed the division crown. The Dodgers eventually knocked the Giants out of the playoffs that October, but their elongated path through the postseason as a wild card team left them gassed in the NL Championship Series. They were eliminated six wins shy of a repeat title.

For president of baseball operations Andrew Friedman, the experience underscored an all-important truth.

“Our primary goal during the regular season is to win the division,” Friedman said. “That is what we feel like puts us in the best position to accomplish our ultimate goal.”

Thus, with another tight division race looming this year, the Dodgers didn’t wait to act aggressively this week.

Austin Barnes and Chris Taylor were struggling. Dalton Rushing and Hyeseong Kim looked like intriguing big-league options. And in two moves that were made in an effort to “win as many games as we can” in this season’s World Series title defense, Friedman said, the longtime veterans were released to make room for the rookies. Sentimentality lost out to the odds of even slightly better regular-season success.

“This has been a very emotional week for all of us,” Friedman said, addressing reporters hours after Taylor was released on Sunday. Barnes was designated for assignment earlier in the week. “Barnsey and CT have been in the middle of some huge moments for this organization. Both guys have left an indelible mark on our culture and where we’re at this point. So the decisions were incredibly difficult. The conversations were tough.”

“But,” Friedman countered, “with where we are, the division race, the composition of roster, everything — we felt like this was in the Dodgers’ best interest … [to] put us in a position to best win the World Series this year.”

Note the first factor Friedman mentioned in his answer.

Though the Dodgers are tied for the best record in the National League at 29-18, they continue to nurse the slimmest of NL West leads, entering Monday just one game up on the rival San Diego Padres (27-18) and upstart San Francisco Giants (28-19), and only four games clear of even the fourth-place Arizona Diamondbacks (25-22).

With their pitching staff already in tatters, at least temporarily, because of a wave of early-season injuries, the importance of consistent offense has also suddenly heightened; the Dodgers needing to maximize the production of their lineup to help offset a 4.18 team ERA that ranks 21st in the majors.

In a world where the Dodgers were running away with the division, or pitching the way they expected after two offseasons of spending heavily on the mound, maybe they could have tolerated Barnes’ and Taylor’s combined .208 batting average. They might have been more comfortable giving two longtime cornerstones of the franchise a longer leash to turn things around.

Instead, as club brass surveyed this year’s competitive division landscape, they recognized that — this season more than most — every single victory could matter come the end of the campaign. That every single loss would make the challenge of winning another World Series incrementally tougher.

So, as Rushing crushed triple-A pitching and Kim excelled in what was initially planned to be only a brief big-league call-up, the Dodgers did what they felt like they must. Rushing replaced Barnes as backup catcher. Taylor was cut loose so Kim wouldn’t be sent back to the minors. And a roster that once seemed too top-heavy now has, at least in theory, more potential impact options to bring off the bench.

“We didn’t feel like coming into the season this was something that we would necessarily be doing in May,” Friedman said. “But with where we were, all things factored in, while not easy, we felt like it was the right thing to do.”

There were other reasons, of course, the Dodgers felt motivated to make such emotionally conflicting decisions now.

Manager Dave Roberts noted that Rushing (who was batting .308 in the minors this year, and has started his big-league career an impressive four-for-10) and Kim (who has hit .452 since arriving in the majors, and has impacted games with his versatile glove and lightning-quick speed) deserved opportunities for more prominent roles.

With most of the team’s core players on the wrong side of 30, there are longer-term considerations about developing younger talent as well.

“I think some of it is the [division] race,” Roberts said. “Some of it is, you still want to continue to develop young players and give them opportunities with a veteran ball club.”

Eventually, it was always likely that Rushing would force his way to the majors, and that Kim would carve out a niche with his well-rounded skill set.

But the early pressure being applied by the team’s NL West rivals still sped up that timeline. The Dodgers remember what happened in 2021. And, wary of having that reality repeat itself, they didn’t wait to begin acting with urgency this year.

“We saw it in 2021, winning 106 games and not winning the division,” Friedman said. “We have a tough division [again this year]. We’ve got some really good teams in our division who are playing well. And so for us, it’s about doing everything we can each night to try to win a game.”
