Grabs win in return outing
De Leon (1-0) earned the win Sunday against the Tigers, allowing three runs on eight hits and three walks while striking out eight over 6.2 innings.
Analysis
Making his first MLB appearance since 2023, the right-hander shook off the rust, allowing his only damage on a Javier Baez three-run homer in the fourth inning. The Red Sox turned to the 33-year-old with the AL East already decided and a Wild Card spot secured, but despite the long layoff, he cruised through the remainder of his outing and was effective enough to earn the victory.

Past Fantasy Outlooks
2021
2019
2018
2017
2016
Acquired from the Rays in November 2019, De Leon spent most of last season at the Reds' alternate training site, making only five appearances and getting shelled in two of them. The 28-year-old was flashing some improved heat, averaging 95.1 mph with his fastball, but he didn't have enough command of it to be effective in his limited opportunities. At one time, De Leon was viewed as a top pitching prospect with an electric changeup, but injuries over the last few years derailed his development. If he can pair his new-found velocity with some control, he could still emerge as a useful arm for a Cincinnati team that could be looking to replace a lot of innings in the near future if Sonny Gray and Luis Castillo follow Trevor Bauer out the door. Until he offers even a glimmer of hope that he'll be able to put it all together though, De Leon is just another arm fighting for a low-leverage spot in the bullpen.
