Fills in for injured Correa
2BHouston Astros
August 20, 2019
Mayfield replaced shortstop Carlos Correa after Correa left Monday's game with back discomfort.
ANALYSIS
Mayfield started at second base to give Jose Altuve a break but needed to adjust when Correa departed after his first-inning at-bat. Correa is listed as day-to-day, so Mayfield, who was called up to replace injured utility infielder Aledmys Diaz (head), could get some at-bats while Correa mends.
