Frasor is a right-handed middle-reliever with a 3.34 ERA in 29 2/3 innings for Texas. He has struck out over a hitter per inning this year, although he is walking 4.2 hitters per nine innings. He has a reverse split this year with lefties actually faring worse against him than righties, although his career numbers are pretty even. The eleven year Major League veteran has a 3.65 ERA over his career, pretty much exclusively as a middle reliever for the Blue Jays, White Sox, and Rangers. Frasor earns about $700,000 over the remainder of the season and is a free agent at the end of the season.
Spencer Patton was a 26 year old non-prospect for AAA Omaha. The right-hander was originally a 24th round pick in 2011, and had a 4.08 ERA in Omaha, but with 60 strikeouts in 47 1/3 innings.
To make room on the roster, the Royals sent reliever Louis Coleman to Omaha. The club also designated Jimmy Paredes for assignment to clear a spot on the 40 man roster.
