Peterson entered Tuesday's 7-0 win over the Yankees as a pinch hitter and walked.
It was the second overall appearance for Peterson and his first time at the plate this season. He pinch hit for rookie Blaze Alexander, who started at DH, in the eighth inning and finished the game at second base. Peterson's versatility will keep him around, and he could provide value in the steals category, but he'd need regular opportunities to do that.
