The Diamondbacks have signed Max Kepler to a one-year deal, but the move is more about managing his PED suspension than adding a significant talent to their roster. Kepler, who tested positive for Epitrenbolone last January, is currently serving an 80-game suspension, which he has been doing as a member of the Phillies. This suspension, which started before the Diamondbacks signed him, means Kepler will be eligible to play for Arizona on June 25th, 2026, after a couple of weeks of minor league ramp-up time.
The financial terms of the deal are not disclosed, but it's safe to assume Kepler will be earning a prorated salary over the remaining 2026 season. His performance with the Phillies last year was underwhelming, with a .216/.300/.391 slash line and 18 home runs in 474 plate appearances. Even before the suspension, Kepler's market was likely to be challenging due to his lack of production.
Kepler's career wRC+ (weighted runs created plus) has been around league average, with a .235/.316/.425 slash line over 1199 plate appearances with the Twins and Phillies. However, his performance against left-handed pitching has been a concern, which has limited his role as a true everyday player. Kepler has expressed frustration over his platoon role, particularly when he wasn't in the lineup for three straight games when the Phillies faced left-handed starters.
Despite being more productive against right-handed pitching, Kepler's success against righties has been modest, with a .240/.324/.446 slash line. His best years came earlier in his career, and since Opening Day 2022, he has batted just .237/.315/.408 against right-handed pitchers.
In terms of defense, Kepler has been a standout in right field during his prime years with the Twins. However, his defensive metrics have declined due to knee problems, and his move to left field in Philadelphia resulted in improved defensive statistics, including +2 Defensive Runs Saved and 0 Outs Above Average over 773 1/3 innings.
The Diamondbacks' signing of Kepler is a strategic move to manage his suspension rather than a significant addition to their roster. While he has the potential to contribute offensively and defensively, his performance against left-handed pitching and the cloud of the PED suspension make him a risky investment. The Diamondbacks are likely using this deal to gain some flexibility and potentially trade Kepler if his suspension is lifted, or they may use him as a mentor for younger players.
