No. 3: Michael Kopech, Chicago White Sox
Chicago White Sox closer Michael Kopech is a name that the Phillies have already been attached to in trade rumors dating back to the middle of June. The former starting pitcher made the transition to full-time closer duties at the beginning of the season, and the results so far have been a mixed bag.
The former top prospect has a lively fastball that can exceed 100 mph, and after a failed stint as a starting pitcher, the White Sox decided to see if his high velocity would play well closing out ball games. Kopech has recorded nine saves in 14 chances, but his 5.18 ERA, 1.43 WHIP and 23 walks in 40 innings don't inspire a lot of confidence in late-game situations. With 55 strikeouts in those frames, teams may be intrigued by the right-hander's 12.38 K/9.
It's possible the Phillies could trade for Kopech, but it's more likely they would use him as a late-innings power arm ahead of Hoffman and Alvarado. The 28-year-old carries one more season of team control and won't be a free agent until 2026. This is a trade that is easy to see the Phillies making to add to the bullpen depth, and it would likely require at least one top prospect to get a deal done.
