Larnach is a MLB bat, but he doesn't make sense on this roster anymore. As already mentioned, the roster has enough LH OFs and he's a liability defensively anyways. On a one year deal and a FA next year, he's essentially a cheap veteran who is unlikely to be back with the team in 2027 so why not trade him and try out the prospects in his place, Roden early in the year and then Rodriguez/Jenkins later on. I don't see much risk in moving on - like Bader and many other guys on one year deals, if they do have a career year then they're signing elsewhere regardless. This team isn't going to be good so might as well play the prospects where you reasonably can.
