Pleased to meet you <a href="http://chungsol04.com/skyBoard/view/gallery/77">approved pharmacy</a>  D’Arnaud, who had been called up Friday night to cover for John Buck’s paternity leave, got thrown right into the fire Saturday night, having to learn the Mets starter and bullpen early and quickly. He allowed three stolen bases — although one was clearly more a result of Mejia’s delayed delivery — and was charged with a passed ball in the fifth. The catcher, who was acquired from Toronto in the R.A. Dickey trade, drew a walk in his first major league plate appearance and walked again in the eighth. He went 0-for-2, including grounding out with runners on second and third in the fifth.
