In 39.1 innings, Huff is 5-1 with a 4.35 ERA, with 32 Ks and 16 BBs. While those are not dominating numbers, he has dominated the minors for the last two seasons, and was also dominant at UCLA, and currently ranks 8th on Baseball America's list of prospects in the Indians system.
He has a make-up somewhat reminiscient of Cliff Lee, throwing a low 90's fastball with deceptive speed, mixing it in with a great changeup. While his curveball is not dominant, his slider has evolved into a great pitch, and his inflated ERA can be partially attributed to his working on that pitch.
As for who could be sent down? While many have speculated that Masa Kobayashi could be released, or that Valbuena could be sent down, here's a quote from Eric Wedge after last night's game, in regard to Jensen Lewis:
"He's throwing," Wedge said of Lewis. "I'm tired of watching him throw. He's got to pitch. He's got a lot of moxie, got a lot of guts. He has good stuff. But you've got to pitch. If you're going to make it up here, you can't miss spots by a foot or a foot and a half and expect to have success."While Kobayashi has been a mess, and recent interviews make it sound as though he's lost all confidence, sending Lewis down to Columbus to get straightened out might make the most sense.
Unless they bring up two pitchers....
