Evan Gattis to replace Erik Kratz on Astros' roster

BOSTON --- Set to be recalled before Tuesday night's series opener against the White Sox, Evan Gattis will take Erik Kratz's place as the Astros' No. 2 catcher behind Jason Castro.

Gattis caught four games with Class AA Corpus Christi as he worked to re-acclimate himself to the position. Tuesday is the first day he is eligible to be recalled. Players who are optioned must spend 10 days in the minors unless an injury occurs on the major league roster.

Gattis won't catch Dallas Keuchel on Tuesday but will catch during the three-game series in Chicago, according to manager A.J. Hinch. It's likely the right-handed hitting Gattis will start at designated hitter Tuesday given the White Sox are starting a lefthander in Carlos Rodon.

Before he was optioned, Gattis was batting .203 with a .570 OPS in 70 plate appearances. In seven games with Corpus Christi – he served as DH when he didn't catch - he batted .360 with three home runs and six RBIs.

The Astros are expected to announce an official roster move regarding Kratz on Monday. Acquired just before the season in a trade with the Padres, Kratz batted .069 (2 for 29) and started behind the plate in nine of 39 games.
