The Kansas City Royals have acquired veteran reliever Jason Frasor from the Texas Rangers for Triple-A right-hander Spencer Patton.
The trade was made Wednesday, the same day Patton was scheduled to participate in the Triple-A All-Star game. The Rangers will assign him to Triple-A Round Rock.
Frasor was 1-1 with a 3.34 ERA in 38 appearances this season, his second in Texas. He spent nine seasons with Toronto (2004-12), returning to the Blue Jays after being traded to the White Sox in July 2011 and finishing that season in Chicago.
Patton is 4-3 with a 4.08 ERA and 14 saves in 34 relief appearances for Triple-A Omaha this season. He has 60 strikeouts in 46 1-3 innings while holding opponents to a .161 batting average.
