John Heyman via his Twitter page is reporting that the Yankees will call up Francisco Cervelli, Ramiro Pena, Mark Melancon, and Mike Dunn tomorrow.
Like I said earlier today, I'm very interested in seeing Dunn pitch at this level. In 37 games with Double-A Trenton and Triple-A Scranton/Wilkes-Barre Dunn is 3-3, with 2 saves, and a 3.34 ERA. In 72.2 innings pitched, he's allowed 27 ER and 58 hits, he's also walked 46 and struck out 98. With Scranton he had a 2.33 ERA in 11 games.
