The Mets recalled Weisenburger from Triple-A Syracuse on Friday.
He'll give the Mets a fresh bullpen arm for this weekend's Subway Series against the Yankees. Weisenburger has made three appearance for the Mets this season, allowing one run with a 4:2 K:BB over 4.1 frames. The 28-year-old has mainly been used as a starting pitcher in the minors this season, so he's capable of providing length.
