Kaz Matsui is headed toward rehab starts with Corpus Christi, and apparently will be back at 2d base for the Astros soon. Matsui's splits at the ML level are very odd this season. Kaz , who is a switch hitter, has been putrid against RHP, but great against LHP. His stats (BA, OBP, OPS): vs. RHP, .193, ..260, .497; vs. LHP, .323, .400, .916. Matsui's splits are fairly even on a career basis; and he was better vs. RHP (approximately 40 point OPS difference) last year. This could be (and probably is) an aberration from small sample sizes this early in the season. But it also raises the question (in my mind, anyway) whether some type of injury affected Kaz's LH batting, but not his RH batting, this year.

In case you are thinking about a platoon with Maysonet...he doesn't appear to be a strong platoon candidate. Maysonet, who is RH batting, has fairly strong opposite platoon hitting in his minor league career (i.e., he hits RH pitching better). Managers aren't prone to set up platoons in which the batter hits from the same side as the pitcher throws.
