PEORIA, ARIZ.
The late-morning desert sun was pushing temperatures toward 90 degrees at the Arizona Fall League as Kyle Gibson began discussing the rising heat -- on his fastball.
Sitting at a picnic table, with his twice-scarred right elbow tucked to his side, the Twins' 2009 first-round draft pick had a hard time containing his smile.
Gibson had Tommy John ligament replacement surgery on his right elbow on Sept. 7, 2011, but now he looks as good as new, if not better. His average fastball velocity has jumped from 89 to 90 miles per hour pre-surgery to about 92-93 mph in Arizona.
"My stuff is the best it's ever been," Gibson said earlier this month. "I feel better than I've ever felt. I have a little bit more on my fastball. Everything's moving a little bit differently, and it just feels a little more comfortable, really."
Gibson, 25, spent the fall re- establishing himself as the Twins' top pitching prospect and was added to the 40-man roster Tuesday. When he reports to spring training next February, he'll be 17 months removed from elbow surgery and a viable candidate to start the season in the big-league rotation -- if the team lets that happen.
As badly as the Twins need starting pitching, General Manager Terry Ryan remains cautious about Gibson.
"Let's keep it in perspective," Ryan said. "Don't get too carried away with, 'Well, he's dominated all these levels.' He hasn't pitched that many innings in the minor leagues [275 2/3 for his career]. So he'll come in and compete for a spot."
