Casas entered Friday's action slashing .356/.400/.600 through 16 spring training games. The homer was his third in Grapefruit League play.

It was a bittersweet night for the Red Sox as Casas' homer came shortly after closer Kenley Jansen exited with a trainer. Fortunately, manager Alex Cora said after the game Jansen "should be fine" after experiencing lightheadedness.

Four spring training games and six nights separate Boston from Opening Day on March 30.
