Astros place INF Diaz (hamstring) on 10-day IL

The Houston Astros placed infielder Aledmys Diaz on the 10-day injured list Monday with a left hamstring strain. Diaz is batting .286 with five homers and 22 RBIs in 32 games in his first season with Houston.

Acquired in a November trade with the Toronto Blue Jays, Diaz has started games this season at six positions: first, second and third bases, shortstop, left field and designated hitter. The team called up 28-year-old infielder Jack Mayfield to make his major league debut after seven seasons and more than 600 games in Houston's farm system.

In 40 games this year at Triple-A Round Rock, Mayfield batted .283 with 10 homers, 31 RBIs and 34 runs scored. Mayfield originally signed with the Astros as an undrafted free agent out of the University of Oklahoma in 2013.
