"That's not my call. But he has all the stuff that warrants him being able to pitch in the big leagues for a long time," said Hasler, who has joined the White Sox for a brief time before going to Arizona for instructional league action. "He has a plus slider, plus fastball, good life, good late life. Competitive, plus changeup. So he's got all the makings, absolutely."
Hasler had nothing but high praise for Rodon, who moved from the Arizona Rookie League to the Carolina League to the International League in less than two months after agreeing to terms with the White Sox on July 11. Rodon, 21, posted a 2.92 ERA over nine games, of which six were starts, covering 24 2/3 innings. He fanned 38, walked 13 and did not allow a home run.
There was a rust factor involved at first for Rodon, who hadn't pitched since May 16 during his last start for N.C. State. That rust disappeared quickly and his superb raw stuff and impressive mound presence took over.
"What you would expect out of a kid coming from a major Division I program. He's really confident," Hasler said. "He's really competitive.
"So competitive that he really wasn't happy with giving up a hit or a run in Rookie ball or A ball. I understand he was a little rusty, but he wasn't happy with that. He wanted to succeed just like everybody else. He's extremely competitive and a great kid. A really good kid.
"Does he have some things to work on? Sure," Hasler said. "Command of all of his pitches, things like that. He understands it. He knows it. The plus slider is well advertised, but everything else around it is pretty darn good as well."
