This could be a big postponement day as rain and snow threaten games in New York, Chicago and Detroit.

The Astros and Cardinals meet again in St. Louis, this time with Houston sending Roger Clemens to the mound against Mark Mulder. Clemens is off to a terrific start after having a rather high spring ERA. Clemens leads the majors with an 0.43 ERA and has struck out 26 in 21 innings while walking only 2. Mulder found the truth in his last start against the Pirates after two lackluster performances to start the season.

Battling Clemens for the NL ERA lead today will be Tim Hudson, who has posted an 0.82 mark so far in 2005. He'll face the Phillies and Randy Wolf. Wolf has struck out over five times the number of batters he's walked this season; given the Braves low OBA of .300 he probably won't walk many more today.

Two very good matchups out west today. Shawn Chacon is back in the rotation and made to good first starts for the Rockies, allowing 1 run in each of his first two starts. He only pitched six innings in each, but the encouraging thing is that the starts were in Coors and the BOB, two good hitters parks. He'll face Odalis Perez, who is off to a 3-0 start for the Dodgers. Perez has not allowed a home run in his first 17 2/3 innings, and opponents are only slugging .230 against him.

The Padres visit the Diamondbacks and send Jake Peavy to the mound against Brandon Webb. Webb has only allowed 1 HR this year despite three games in either the BOB or Coors. Peavy continues his spectacular pitching of 2004, coming in with 26 K and only four walks in 20 2/3 innings pitched.

Enjoy!
