He really sucks in close games, I mean, REALLY. Look at his Fangraphs page and scroll down to their Shut Down/Melt Down, it's an even 44/44, the latter will go up when they update tomorrow. Just don't throw him in a close games.
I think DD stand pad on pulling big trades. He has pretty much exhausted that were deemed expendable. Now we're left with a front loaded system headline by Moncada and Benintendi, perhaps two of the most coveted guys out there. I think they're off limits set by higher ups that outranks DD. The latter might get a call up to fill the hole in LF right now anytime. We know Holt best role is back on the bench.
We do need a reliever or two. This bullpen has a lot of mileage and injuries to it, definitely a concern.
