UNDATED (AP) — Both the Washington Nationals and Detroit Tigers have lost an important member of their offense.

Nationals left fielder Jayson Werth has been put on the 15-day disabled list with a bruised left wrist after getting hit by a pitch Friday in San Diego. His second stint on the DL this season is retroactive to Saturday.

Tigers slugger Victor Martinez has been placed on the 15-day disabled list after struggling in his return from offseason knee surgery. The team says he has left knee inflammation after undergoing surgery in February to repair a torn medial meniscus. Martinez is hitting just .216 with one homer and 15 RBIs in 111 at-bats this season.
