The Mariners, as one would expect with GM Jerry Dipoto at the helm, continue to be active in trade discussions and are receiving the most interest in outfielder Domingo Santana and lefty Roenis Elias, per Ken Rosenthal of The Athletic (subscription required). Interest in Santana is strong enough that Seattle “will at least consider trading him,” Rosenthal writes.
Santana, 27 in early August, is in his first season with the Mariners after coming over from the Brewers in an offseason swap that sent Ben Gamel to Milwaukee. The slugger has been every bit as productive as Seattle could have reasonably hoped upon acquiring him, hitting at a .280/.346/.489 pace with 19 home runs, 19 doubles, a triple and six steals. Santana, though, has also fanned at a 29.5 percent clip and racked up more total strikeouts (122) than any player in Major League Baseball.
More concerning than Santana’s strikeouts, however, is his glovework in the outfield. Santana’s -14.4 Ultimate Zone Rating and -12 Outs Above Average are the worst marks of any outfielder in baseball. Only Colorado’s Ian Desmond (-16) has fared worse than Santana (-13) in the estimation of Defensive Runs Saved. It’s not fully clear what has prompted the downturn in Santana’s defensive ratings. A year ago in Milwaukee, he drew above-average marks from all three of those metrics. And while those positive ratings look to be an outlier relative to the rest of his career, Santana has also never struggled anywhere close to this extent in seasons past.
