Chris Martin
Chris Martin is one of the few cases from the Alex Anthopoulos era where the Braves made a mistake by not keeping a guy around. Martin did battle some injury issues from when Atlanta acquired him from the Rangers to when he left in free agency after the 2021 season, but pitched quite well when he was on the mound for the most part. Since then, Martin has posted a 2.10 ERA across 115 appearances with the Cubs, Dodgers, and Red Sox and it is hard not to wonder how much better the Braves' bullpen would have been had Atlanta hung on to him.
2024 spring training for Martin, however, is not off to the best of starts. Martin has yet to appear in a spring training game for Boston as he has been slowly ramping up on the backfields. More recently, a bullpen session resulted in a groin injury that was a minor setback in his progression. Everything points to the injury not being serious and he should be ready for Opening Day if everything goes to plan.
Eddie Rosario
Braves fans need not be reminded of Eddie Rosario's impact on the Braves franchise. While his last two seasons with Atlanta did not go nearly as well, his performance against the Dodgers in the 2021 NLCS where he basically carried the Braves to the World Series will go down in Braves history as an all-timer.
Unfortunately, Rosario's inconsistency the last couple of years ultimately led to the Braves moving on from him this offseason in favor of Jarred Kelenic. Rosario had to wait a long time to find employment which he eventually did with a minor league deal with the Nationals. In fact, it took so long that Rosario has yet to play in a spring training game as of 3/11 and his best case scenario at the moment is making the Opening Day roster of a team that might be one of the worst in baseball in 2024.
