I think they like the roster flexibility that Aceves provides to this point. I floated this on the scout forum, and if the Yankees promote any more kids, and then a player comes back from injury, then that player may lose an option or worse, have to be DFA'd. We have no shortage of power relief options in the minors. Montgomery, Burawa, Pinder, Ramirez et al. Once we get a definitive answer on Beltran and get Kelley and Pineda back, we should be close to full strength. Remember, two key pen cogs are in the rotation currently in Nuno and Phelps. I thought both of those guys would be playing key pen roles this yr. Now, they're pressed into duty. I also like what Whitley has brought to the table. Wait until you see him as a reliever. He's a 90-92 guy in the rotation. In relief, he's a 94-95 guy and his power plays off that solid change. I do think we are pressing Dellin a lot and Warren is getting a lot of run right now. When Kelley returns, Warren will slot into the 7th inning role again and on nights when Tanaka pitches, he shouldn't be needed.
