MESA, Ariz. -- Hector Rondon, the Cubs' Rule 5 Draft pick, has looked sharp in his two outings. The only question is whether the right-hander can handle two innings of work in a game.
In his two outings, Rondon has given up one hit and struck out two over two innings.
"I feel really good," Rondon said.
"That was pretty nice," Cubs manager Dale Sveum said of Rondon's outing on Thursday against the Athletics. "The ball was coming out of his hand pretty well. He threw a couple real good sliders, and I didn't know he had that good of one and he threw one with a lot of tilt on it. With health, that might be a pretty good steal."
Rondon, who was the Indians' Minor League Pitcher of the Year in 2009, has been slowed by two elbow injuries.
"He has legitimate stuff," Sveum said. "[Thursday], he was 92, 93 [mph] with a good slider, he threw strikes. He's always been a strike thrower. That's nice to have in your back pocket. The guy's always been a strike thrower, and now that he's completely healthy -- the only kicker is we have to get him to be able to throw two innings."
They want the right-hander to build up arm strength so he can throw two innings before Spring Training ends. He's been limited the last three seasons after undergoing right elbow UCL reconstruction surgery in August 2010. He fractured the same joint during winter ball in Venezuela in '11.
