Dude, you don't get to disallow all arguments for why a player deserves a spot on the roster. Slater has proven over 8 seasons that he's a reliable baseball player, who has put up average to much better than average offensive production in most of those seasons, while providing cromulent defense at all 3 OF positions.
We know what we have in Oscar Colas. Colas has proven to be a bonehead in the field. Two glaring misplays happened in spring training, once in LF when he got hit in the face with a fly ball, and once in RF, charging a single with the thought of throwing out a guy halfway home already, and he let the ball get passed him to advance all runners. Colas has not distinguished himself with the bat, while playing in a bandbox of a ballpark. He also seems to be a clubhouse problem, or at least have attitudinal problems that likely make him uncoachable. I'd imagine that for 4 years, his coaches have been telling him that on a single to RF, make sure to pick up the ball, and understand you're not going to throw out a guy halfway home, already.
We also pretty much know what we have in Fletcher, DeLoach, Julks and Cal Mitchell. I mean, you screamed for a solid year about what bums the first three were, how those trades were complete disasters, oh, and they're all old. So what is it you didn't see in 2024 you think you're going to see this year?
And playing a 31-year-old veteran in baseball games isn't "wasting at bats". The games have to be played, and who better to play them than capable baseball players? Everybody here is screaming about "watchable" baseball. Why do you want to see players you've already dismissed as subhuman trash kick the ball around the outfield and pop out in the rare moments they get runners on base?
I mean, if losses don't matter, I look forward to never hearing about this 41-121 2024 record again.
