The Texas Rangers added another left-handed relief option Thursday by acquiring John Gaub on a waiver claim from the Tampa Bay Rays.
Gaub has spent the season with the Rays' Triple A team in Durham, going 0-1 with one save and a 4.32 ERA over 16 relief appearances. He has held left-handed batters to a .185 average.
He was added to the 40-man roster and assigned to Triple A Round Rock. The Rangers didn't need to make a corresponding move because they had only 39 players on the 40-man after releasing -- and later re-signing -- right-hander Justin Miller last month.
Gaub, 27, has spent time in the Indians' and Cubs' organizations, as well. He made his big-league debut with the Cubs in 2011, posting a 6.75 ERA over four relief appearances.
Never miss a local story.
He joins Ben Snyder as the other lefty in the Express bullpen. Michael Kirkman has moved into the rotation, and Neal Cotts is still progressing on his throwing program as he recovers from a strained left lat muscle suffered in spring training.
Dallas Cowboys quarterback Tony Romo will throw out the ceremonial first pitch before Wednesday's game against Seattle.
The Rangers are sold out of reserved tickets for this weekend's series against Toronto. As of Thursday, a limited number of obstructed view and scattered single seats remained, and more than 2,000 standing-room-only tickets for each game.
Left-hander Kevin Matthews, the team's first-round pick in 2011, has been promoted to Low A Hickory. Matthews went 1-3 with a 2.20 ERA in 12 games, including eight starts, in stints at the Arizona Rookie League and Short A Spokane last season.
