Bobby Abreu will be the designated hitter on Tuesday and Wednesday against the Mariners when the Mets face back-to-back left-handed starting pitchers in an American League ballpark.
Abreu, 40, started in right field Sunday against the Padres.
He is 2-for-27 as a pinch-hitter this season and hitless in his last 18 at bats as a starter.
Terry Collins told reporters that going from full- to part-time player is difficult for someone like Abreu, who is a former all-star used to playing everyday (Rubin, July 20th).
Abreu is hitting .259 with a .349 OBP and has one home run this season. He is a career .295 hitter with a .392 OBP and 2,465 hits.
