my view was that he had a good fastball, fairly straight but not farnsworth-straight. it certainly jumped out of his hand well and the hitters were having some difficulty catching up to it. it did look to me like he got a little more movement when he was in the low to mid 90s, while his high 90s fastballs were straighter and lacked in command a bit more. that's similar to carlos zambrano, who used to throw in the high 90s when the cubs stupidly flirted with him as a reliever in the early part of this decade. his secondary stuff was actually better than i'd expected, given the reports on him during the offseason. but, his slider didn't seem to have a whole lot of bite to it, and too many of them sorta floated up to the plate. if he keeps doing that, those will start getting hit harder. i believe he flashed two changes, and they looked okay - the difference between the change and the fastball is 10-15 mph, which is plenty, although there's always the question of whether the change is deceptive enough (i.e., looks like a fastball when it's thrown). all in all, he looked very good. i think he has to tighten up his command and throw his slider with better bite more consistently, but he certainly looks like he has a big-league arm. i'd like to see him keep starting in iowa the rest of this year, as he seems to have good potential. as a good athlete, one would expect that he could maintain his stuff over several innings, and also add some things with his hitting, bunting and fielding. as a final note, i'll say that the cubs may end up being validated on what was a controversial move that was panned by many of us. he may have just been very green last season, which could explain why he seems to have improved by leaps and bounds.
