Trea Turner has started hitting well again, although still lacking some slug, but his defense is a major concern right now.
Turner started the season hitting .223 through 58 games with a .622 OPS. Since June 1, he is slashing .274/.310/.393, which is much better. It's still not what the team was expecting from him, but he's at least not an automatic out. However, his defense has been abysmal all year.
He has a minus-nine defensive runs saved and a minus-six outs above average. Outside of 2025, he has been a terrible defender at shortstop for the Phillies. The team should consider moving him to the outfield. He is still one of the best athletes in baseball, and his speed would allow him to cover plenty of ground in the outfield. He does have experience there, playing 45 games in centerfield with the Washington Nationals early in his career.
In his previous three seasons, his bat was so good that the Phillies were willing to put up with the defensive deficiencies at shortstop. However, now his bat is average and the Phillies need some more production from the outfield spots as is. The Phillies may not have a much better replacement for him at shortstop offensively right now, but his defense is simply not good enough to keep trotting him out there.
The Phillies could explore changing his position, opening the door for a trade to acquire a shortstop at the trade deadline. Turner led all of baseball in errors in 2023 and has 60 errors at shortstop in his time with the Phillies. He has 12 errors this year and is hurting the Phillies with his poor defense.
Ultimately, his hitting has improved after a slow start, but he is still not a winning player right now. He still has a negative bWAR, and moving him to the outfield could get him into the plus by eliminating his poor defense.
