Derek Lowe is probably the best pitcher on the free agent market not named CC Sabathia when you combine level of talent with durability, and he's the only one of the bunch who has proven in the past that he can pitch here. Our infield defense is significantly upgraded from the '03-'04 campaigns where Lowe struggled with BABIP above his career averages, that should help Lowe's numbers tremendously.
Lowe has failed to manage 200 innings twice in the years he was a fulltime starter: THe first time during his weak 2004 campaign, the second, in 2007 when he pitched 199 1/3 innings. As long as you're satisfied with the quality, you'll get plenty of quantity.
THis is a peripheral interest, but we should also pursue Lowe out of the available starters because he's similar enough to provide mentorship to one of our top young arms. Lowe and Masterson are not identical, but they are quite similar, and if Lowe is willing to take Masterson under his wing, and not afraid to learn something from the kid, I think that would only be a good thing.
