The Nats are playing great baseball, with 5 straight wins and a +1 run differential on the season. That doesn't mean the team cannot be improved, though. Here are a few players currently playing in AAA Syracuse that could give the Nats a hand:
IF Matt Antonelli is tops on my list for a callup. He's better than Bixler and is the only infielder in the Majors or AAA other than Desmond or Espinosa that has a future with the team. If you haven't already, read my interview with Antonelli here.
1B Michael Aubrey has struggled over his last few weeks, hitting .167/.323/.333 in his last 10 games. Still, he's an OBP machine with a little pop and a nice glove. Adam LaRoche's season-ending injury makes me want to call up Aubrey even more, as he's a left handed hitter who can serve as a pinch hitter or defensive replacement for Morse late in games (something Stairs is incapable of).
1B Chris Marrero is in the right place at the wrong time. His AAA numbers are solid (.290/.351/.450), but Morse's hot streak and RH bat make it so calling up Marrero and sitting him on the bench would be a detriment to the 22 year old's development. We'll see him in September I'm sure.
LHP Tom Milone has allowed more HR (5) than BB (4). And 5 HR ain't a whole lot to allow in 70 and 1/3 innings, anyways. With a 19:1 K:BB ratio and a respectable 3.58, we will probably see Milone in DC sometime this season, albeit the role may come as a reliever.
RHP Josh Wilkie probably should have gotten the call in 2009 and 10, but I'll still hold out hope that 2011 will be the year he gets his shot. While peripheral stats aren't as good as they were in 2009 and 10, the fact that he's put up consistently solid ones in three straight years at AAA make him a viable option.
RHP Brad Meyers has less BB (3) than Milone in more innings (76 and 1/3) across two levels. He's been prone to the long-ball in Syracuse (5 HR allowed in 7 starts), but has put up solid stats otherwise. Meyers has spent a considerably smaller amount of time in Syracuse so he's on the bottom of the totem pole. Still, a 24.33 K:BB ratio throughout his minor league appearances this year is awesome.
