Erich Uelmen, Michael Plassmeyer, McKinley Moore
We'll treat this "three-headed monster" as one entry since each of them was so insignificant that it'd be a real stretch to write much about them individually.
First, Uelmen. He was most notable for becoming the first "U" entry on the Phillies' all-time player registry since Chase Utley. Still, you could be forgiven for missing his one appearance during the 2023 season, as he surrendered four runs in the fifth inning of a 10-1 loss to the Cubs on May 19. Oddly enough, it came less than a year after his MLB debut, which came as a member of those Cubs against the Phillies in 2022. That game was also a blowout win for Chicago, although Uelmen surrendered a home run to Darick Hall (remember when he existed?).
As for Plassmeyer, he received a start in the penultimate game of the regular season and was destroyed by the Mets to the tune of ten runs (nine earned) in 3 2/3 innings as the Phillies looked to rest some arms. You have to feel bad for the guy, having this kind of result in his first MLB start (he debuted with two relief appearances in 2022). On the bright side, literally nobody was watching this game, as the last series of the season didn't matter. Although, the Phillies were one win away from potentially having had homefield advantage in the World Series over the Rangers. Just food for thought.
Lastly, 2023 also saw the MLB debut of McKinley Moore, as he got into three games for the Phils and posted an 18.90 ERA over 3 1/3 innings, all coming between April 10 and April 15. Moore threw 86 pitches just to get ten outs over the three appearances, allowing five hits, five walks, and hitting a pair of batters. Things went better for him in the minors, but it remains to be seen if he'll be afforded another shot with the big club next year.
Hopefully you enjoyed this trip down recent memory lane. Now feel free to forget all of these players.
