The Mets have announced that they will activate Mike Baxter from the disabled list tomorrow and option Kirk Nieuwenhuis to Triple-A Buffalo. Baxter, as you certainly recall, made an incredible catch to help preserve Johan Santana's no-hitter on June 1, but he broke his collarbone and injured his ribs when he slammed into the outfield wall.
Before the injury, Baxter had hit .323/.392/.523 in 74 plate appearances. Each rate is significantly better than that of any other Mets outfielder. All but 10 of his plate appearances came against right-handed pitchers, against whom he hit .375/.438/.607. He is far from a proven hitter at the big league level, but Baxter should immediately take away playing time from Jason Bay against right-handed starting pitchers.
Nieuwenhuis was called up on the second day of the season to fill in for the injured Andres Torres in center field, but he has been awful at the plate after hitting .325/.386/.475 in the month of April. Since May 1, Nieuwenhuis has hit just .223/.287/.337.
