M's Concerns: the Back End of the Rotation and the Lineup

(Win Probability Graphing by Fangraphs)

Miguel Batista is a number 5 starter, and probably an above average number 5 in the big leagues. He certainly looked much sharper than the Orioles' Adam Loewen. Up until he lost his command in the fifth inning and started issuing walks. Nine base on balls issued by the Seattle pitching staff versus just three free passes from Loewen (who clearly didn't have his best stuff today) made all the difference in this game. Not to mention the 4! errors committed by the Mariners in this one. As far as "back of the rotation" starters go, Batista is the great unknown. We've seen the effective sinker ball from Carlos Silva and we cringe when Washburn gets a road start. I hope we see a more consistent Batista as the season wears on.

Why is Richie Sexson batting cleanup? He did not look comfortable in the batter's box in this one as he took some ugly hacks at pitches way out of the strike zone. His .205 batting average with just 63 RBI's last season looks more like a decline than an off-year at this point. The M's need more production than that from the number four slot.

On the other hand, Mike Morse has an impressive canon. His ability to gun down Brian Roberts at the plate on the heels of Shawn Green's errant pickoff throw into center field was most impressive. I hope we see a lot more of him (and a lot less of Willie Bloomquist).
