The Texas Rangers activated right-handed pitcher Tyson Ross from the 10-day disabled list Saturday to make a start against the visiting Houston Astros.

Ross (2-2, 7.52) was placed on the disabled list on July 24 with a blister on his right index finger. He made two rehab starts for Double-A Frisco, going 1-1 with a 2.31 ERA.

He last pitched for the Rangers on July 23, when he threw 3 2/3 innings and allowed five runs on four hits but didn't factor into the decision in a win over Tampa Bay.

To make room for Ross on the roster, the Rangers optioned outfielder Ryan Rua to Triple-A Round Rock.

Rua had not appeared in a game for Texas since his July 31 recall from Round Rock. Overall, he is hitting .202 with three homers and 11 RBIs in 44 games for Texas this season.
