Neal Cotts is back in the big leagues for the first time since 2009.
The Rangers, assuming they play tonight, will purchase the contract of the 33-year-old left-handed reliever from Triple A Round Rock as the corresponding move to optioning Monday's starter Josh Lindblom back to Round Rock.
Cotts will give the Rangers a lefty a night after Joseph Ortiz and Michael Kirkman threw a substantial amount of pitches and were likely unavailable.
Cotts has been dominant so far with the Express. He has a 0.78 ERA over his first 15 appearances, including holding left-handed batters hitless with 22 strikeouts and three walks.
Cotts has spent the past two seasons in the Rangers organization. He joined the team prior to the 2012 season on a minor-league contract and almost made the Opening Day roster until he suffered a strained right lat late in spring training.
Cotts spent the year at Round Rock, posting a 4.55 ERA over 25 appearances, and re-signed with the organization last February on a minor-league deal with an invitation to big-league camp.
Cotts last pitched in the major leagues with the Chicago Cubs in 2009. He has played in parts of seven seasons with the Cubs (2007-09) and the White Sox (2003-06), compiling a 4.63 ERA 284 career appearances.
Here are a few other moves the Rangers announced:
* Right-hander Nick Tepesch won't make his scheduled start Wednesday as he has a blister on his right middle finger. Assuming the Rangers play tonight, they would then bring up right-hander Ross Wolf to make a spot start. Wolf, who has had two big-league stints with Miami and Oakland, has a 1.85 ERA over six starts with Round Rock.
* Finally, as expected, the Rangers announced that catcher A.J. Pierzynski has been activated from the disabled list with Robinson Chirinos being optioned back to Round Rock.
