The Mets were buyers over the weekend.

Now they’re sellers, and have a new, young catcher to show for it.

The Mets traded back-end starter Jason Vargas and cash considerations to the rival Phillies for Double-A catcher Austin Bossart on Monday, only a day after sending two pitching prospects to the Blue Jays for stud pitcher Marcus Stroman. The Mets saved $2 million in the Vargas deal, and it remains unclear what the their plan is with Wednesday’s 4 p.m. trade deadline approaching.

Bossart was Philadelphia’s 14th-round pick int he 2015 draft, and is hitting .195/.303/.335 in 63 games this season with Double-A Reading. Bossart’s biggest asset comes behind the plate, where he is described by Baseball America as a solid defender and receiver. But Bossart seems to have had trouble adjusting to higher-level pitching.

The 26-year-old played alongside the son of Mets CEO Jeff Wilpon, Bradley, for one season at Penn. The younger Wilpon was drafted by the Red Sox in the 36th round of the 2014 MLB draft, but doesn’t appear to be playing baseball any longer.

Vargas, the 36-year-old left-hander, has emerged as a reliable starter over his last 16 outings, in which he’s allowed three runs or fewer. He is 6-5 with a 4.01 ERA in 19 games this season.
