The Astros are set to select infielder Jack Mayfield’s contract from Triple-A Round Rock, Jake Kaplan of The Athletic reports. Mayfield will take the place of fellow infielder Aledmys Diaz, who’s going to the 10-day injured list with a left hamstring strain, and will grab the last open spot on Houston’s 40-man roster.
Mayfield, 28, is finally receiving his first big league call-up six years after joining the Astros as an undrafted free agent in 2013. The former Oklahoma Sooner has seen action at the Triple-A level in each season since 2016, combining for a .262/.320/.452 line with 34 home runs in 970 plate appearances. Mayfield has gotten off to a .283/.362/.572 start with 10 homers in 177 PA this year, which impressed the Astros enough for him to warrant a promotion.
It may be a short-lived Houston stint for Mayfield, who will temporarily fill Diaz’s void as a multi-position infielder. Everyday second baseman Jose Altuve could bump Mayfield off the Astros’ roster when he returns from his own IL stay in the coming days.
