"It hasn't sunk in yet," Patton said. "It has been pretty surreal and exciting."
The Rangers acquired Patton from the Royals on July 16 in exchange for pitcher Jason Frasor. He was 1-1 with a 3.38 ERA and four saves in 15 relief outings for the Round Rock Express.
"He's a strike-thrower, commands the baseball … a competitor," manager Ron Washington said. "We're going to get him out there and see."
The Royals drafted Patton in the 24th round of the 2011 First-Year Player Draft out of the University of Southern Illinois Edwardsville. He was pitching at Triple-A Omaha at the time of the trade.
"I was actually at the Triple-A All-Star game," Patton said. "I was out to breakfast with family when our Minor League coordinator called. I wasn't expecting it but I was happy with it."
To make room on the Major League roster, the Rangers placed Shin-Soo Choo on the 60-day disabled list. The Rangers now have 11 players on the 60-day disabled list.
