Mayfield was called up from Triple-A Tacoma and will bat seventh as the second baseman Wednesday against Detroit, Corey Brock of The Athletic reports.
The infielder was called up to fill the spot of Dylan Moore (calf), who went to the injured list Wednesday. Mayfield had three hitless at-bats with the Angels in early April and has shuttled between the Rainiers and the big-league club since latching on with the Mariners organization April 27.
