Detroit plays host to a great matchup between two young pitchers as Kansas City's Zack Greinke faces Justin Verlander. Verlander started twice so far and did not allow an earned run in either contest. However, he's only received one run in support, so he hasn't earned a decision yet. And although he's allowed two earned runs in his two starts, Greinke pitched much better. He's struck out 12 and walked just one, while is nearly even with 8 walks and 9 K.

Freddy Garcia makes his 2007 Phillies debut tonight as they host John Maine and the New York Mets. Maine's put some runners on base, but opponents are 0 for 9 with runners in scoring position, accounting for his low ERA. Garcia returns from a biceps injury, but his velocity appears to be down:

Asked to reminisce about the Garcia who used to pitch brilliantly against his teams in Cleveland, Manuel said, "You're talking about a guy who threw a 92-97 mile-per-hour fastball with sink. He threw a really heavy ball. He was a power pitcher."

Was being the key word. Garcia rarely hit 90 mph in spring training and made a courtesy 91 mph clocking on single fastball during his rehab start in Clearwater last week -- and that pitch was rumored to be a good yard out of the strike zone.

That said, Garcia's velocity was down last season with the White Sox, yet he managed to win 17 games. As for his confidence following the sore-arm scare, Garcia said that he thought he could go eight innings Sunday.

Given the likely cold temperatures in Philadelphia tonight, I doubt he'll go anywhere near that long.

The Diamondbacks and Dodgers fight for first in the NL West this evening. Brad Penny takes on Edgar Gonzalez. Penny, like Maine, is bending but not breaking. He's allowed a .340 OBA so far, but opponents are just one for ten with runners in scoring position. Five of the six runs off Edgar so far came via four home runs. If he can keep the bases empty, the long balls won't hurt him too much.

Enjoy!
