Next Up: the Arizona Diamondbacks.

The Arizona Diamondbacks are leading the NL West with a record of 39-36 and are coming off a 3-5 lose to the Minnesota Twins.

Tomorrow's pitcher is scheduled to be Dan Haren. Haren throws a mid-nineties fastball, a very good splitter, a change up, and a slider. If the splitter is working, he'll get a lot of swings and misses on that pitch. He throws strikes and rarely walks anyone. He does give up a fair number of hits, though. Given what he has the ability to do, his pitch count can get higher than it should be. He walks more lefties (which really isn't all that many) but righties have a slightly easier time hitting him (eighty percent of his home runs have been to righties.) Last year (as an A), Haren played one game against Boston. He allowed two earned runs (both home runs) on four hits in 7.2 innings. He struck out nine and walked one.

The scheduled pitcher for Tuesday is Doug Davis. Davis is currently in recovery from thyroid cancer. He has a good curveball, a good cutter, and a low-eighties fastball. Control can be an issue for him and when he doesn't have it, he starts walking people. He doesn't give up many home runs but he will dole out the hits. He also gets quite a few strike outs. It's too bad they're playing at Fenway because he is a dreadful hitter. He has a difficult time getting lefties out. He keeps his cool and is confident, even when things are going awry.

Wednesday's pitcher is Randy Johnson. Johnson's fastball now sits in the mid-nineties range. He stills throws the extremely effective low-nineties slider, a split-fingered fastball, and a sinkerball. Lefties still struggle against Johnson but righties have gotten his number a little better. He does play better away than he does at Chase Field.

The Diamondbacks are pretty hard-hitting line up. Their biggest power threats are probably Conor Jackson (1B), Mark Reynolds (3B), and Stephen Drew (SS). Mark Reynolds strikes out a lot, though (like Ryan Howard levels of impatience.) Orlando Hudson (2B), Justin Upton (RF)-BJ's brother- and Chris Snyder (C) are also good hitters.

Defensively, their second baseman and thirdbaseman are prone to errors. Justin Upton has struggled defensively so far this season as well but the man has a rocket of an arm. JD's brother has been a slightly above average shortstop this year and their firstbaseman is also slightly above average.
