Sanchez is best known for his no-hitter in 2006, but in the three seasons since then he's only started about a season's worth of games due to a slew of injuries. He hasn't pitched well in that span, either, going 8-14 with 4.56 ERA and 1.63 WHIP in 32 starts over that span. This spring, though, he's healthy and apparently determined to prove to the Marlins that he's serious about finding his 2006 form on the mound again.
I think my favorite part of the story is the quote Sanchez gives to the Palm Beach Post in the link above, though:
I don't want to be mean about this ... but how did that never occur to a professional athlete before?"Today I threw a lot of pitches in two innings, then I went running, I worked out and I don't feel tired," he said. "Last year and years ago I'd feel tired after any workout. When you lose weight and you feel comfortable with your body, you can do lot of things."
