Arlington, Texas ? The Kansas City Royals have gotten some relief help, acquiring 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 earned-run average in 38 appearances this season, his second in Texas. The right-hander 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.

In 624 major-league games, Frasor is 31-35 with 36 saves and a 3.65 ERA.

The injury-plagued Rangers (38-57) went into the All-Star break with the worst record in the major leagues. They were 21 games behind AL West-leading Oakland.

Kansas City (48-46) is second in the AL Central, 61/2 games behind Detroit.

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 461/3 innings while holding opponents to a .161 batting average.

To make room on their roster, the Royals optioned Louis Coleman to Omaha and designated utility player Jimmy Paredes for assignment.

Texas will fill Frasor’s spot on its 25-man roster before playing Friday at Toronto.
