Mayfield started at shortstop and went 1-for-3 in Sunday's 6-5 extra-innings win over the Angels.
Mayfield made his first start of the season while Carlos Correa got the day off. Mayfield is filling in as the team's utility infielder with Aledmys Diaz (groin) on the injured list, but he's rarely used. Other than Sunday's start, Mayfield has made one appearance as a pinch runner and scored a run.
