Familia is experiencing biceps tendinitis, which the Mets announced before their game on Friday night. While the team tried to put off a disabled list decision on Familia for a couple of days, the bullpen has seen a ton of work over the past few games. Since Matt Harvey's nine innings of brilliance on Tuesday, only Jeremy Hefner has pitched six innings. Shaun Marcum, Jon Niese, and Dillon Gee each pitched five or fewer innings. The team really needs as many healthy arms in the bullpen as a result.
Familia had thrown just 10.1 innings with the Mets after starting the season on the big league roster and spending some time in Las Vegas before rejoining the team. He's posted a 3.48 ERA but a poor 6.20 FIP thanks to identical strikeout and walk rates of 6.10 per nine innings and his propensity to serve up home runs.
Burke's just the opposite when it comes to those numbers, having posted a 7.36 ERA and 2.33 FIP in his brief time with the Mets to begin the season. In Vegas, he's posted a 4.66 ERA and 2.68 FIP in 9.2 innings.
