Pirates could shake up MLB trade deadline by holding onto top target

Pittsburgh Pirates right-hander Mitch Keller is regarded as one of the top players on the pitching market. That may no longer be the case.

According to Ken Rosenthal of The Athletic, the Pirates are uncertain about whether they will trade Keller by the deadline on July 31. At 42-62, Pittsburgh is out of contention for a playoff berth this season. However, they intend to keep Keller for a potential run in 2026.

The Pirates could have one of the best rotations in baseball next year if they remain healthy. Paul Skenes has continued to cement his place as one of the best pitchers in the sport and is their unquestioned ace. Keller would be a solid option behind Skenes as the second starter, while top pitching prospect Bubba Chandler is expected to debut before the end of the 2025 campaign. Injured pitcher Jared Jones showed promise during his rookie season in 2024 and is expected to return by mid-2026.

Complicating matters for Pittsburgh is that Keller's value may never be higher than it is currently. He is in the midst of a career season, having posted a 3.53 ERA and a 1.160 WHIP in 125 innings entering Saturday, with 97 strikeouts and 30 walks. Moreover, Keller is signed to a five-year extension, which keeps him under team control through 2028. 

The Pirates would have several suitors for Keller. The New York Yankees, Toronto Blue Jays, Chicago Cubs and New York Mets are specifically known to be checking in on Keller, although other teams may have interest. The Cubs are reportedly viewing Keller as a backup option. This may also be a factor as the Pirates consider their decision regarding his future in Pittsburgh.

The Pirates' choice could further shake up the trade market. The Kansas City Royals are likewise undecided as to whether or not to shop pitcher Seth Lugo or to work on an extension. If neither pitcher is available, the asking price for arms could skyrocket in a seller's market.
