CHICAGO (AP) The struggling Houston Astros retooled their roster for the second straight day, adding catcher Evan Gattis and third baseman Colin Moran.
Gattis was recalled from Double-A Corpus Christi and was the designated hitter and cleanup batter for Tuesday's series opener at the Chicago White Sox. Houston selected the contract of Moran from Triple-A Fresno.
Manager A.J. Hinch said he wanted to shake up his lineup to create more competition and offense.
''One of the things that I noticed about the team that we struggled with is having our bench players push our everyday players,'' Hinch said. ''I'm hopeful the additions of Tony Kemp and Moran will push (Luis) Valbuena and (Tyler) White, Gattis and Marwin (Gonzalez), guys that have gotten to play quite a bit.
''Having more options is good. We might see a little more fluid interaction between Triple-A and the big leagues if needed.''
Outfielder Carlos Gomez was placed on the 15-day disabled list and right-hander Asher Wojciechowski was designated for assignment. Gomez had a rib injury and was shaken up diving back hard into second on an attempted pickoff Sunday in a 10-9 loss at Boston.
Last-place Houston added 5-foot-6 infielder Tony Kemp on Monday, when catcher Erik Kratz was designated for assignment.
Hinch said he intends to start Moran and Kemp on Wednesday night.
''Those two guys are both playing well in Triple-A,'' Hinch sad. ''They're both different. They're both going to play different roles here. We're looking to jumpstart our offense for a little more consistency.''
