Houston Astros second baseman Jose Altuve exited Wednesday's game against the Oakland Athletics due to right side discomfort after feeling something during a swing in the fifth inning. Although Altuve stayed in the game to complete his at-bat, he was replaced by Mauricio Dubón in the sixth inning. Manager Joe Espada and Altuve both indicated that the injury does not appear to be serious, and Altuve is considered day-to-day. The Astros have been struggling recently, losing eight of their last ten games, and currently hold a 3.5-game lead over the Seattle Mariners in the American League West. Altuve, who has a .302 batting average this season with 19 home runs and 62 RBIs, hopes to return to the lineup soon as the postseason approaches.
