It certainly would be nice to have a hard throwing starter. Maybe they will ease him into the starter's role. As far as blowing out an arm, I think it depends on how he is used and if he is susceptible to it or not. Some players just blow their arms out not because of any faulty coaching but because they are susceptible to it. Others can pitch until their arms fall off without many problems. For example, the Blue Jays have signed Yamada who has been pitching for the Yomiuri Giants for the past two years. He's basically a junk ball pitcher who throws sinkers, sliders, forks, curves, splitters as well as two-seam and four-seam fastballs. He is regularly allowed to throw +120 pitches in games and has exceeded +140 in at least two games that I watched. For some reason, he doesn't seem to get injured (but he did look tired in the WBC). In any case, Toronto while knowing all of this, ponied up the cash.
