With the postseason roster yet to be announced, let us ponder…

Fortunately for the Yankees, Joe Girardi will not be counted on to make any terribly difficult roster decisions. CC, Pettitte, and Kuroda will work the first three games. Martin, Teixeira, Cano, ARod, Jeter, Swisher, Granderson, and Ichiro will be the position players with Ibanez taking most of the DH duties. However, here are a few questions to ponder as we get into the thick of it:

1) Who starts Game 4?

The Yankees could, and probably should bring back Sabathia on 3 days rest. But that is unlikely, especially if the Yankees are up 2-1 at that point. Nova was just booted from the rotation, so Girardi surely isn’t going to 180 on that decision so quickly. Phelps replaced him, but we doubt Girardi would start such a young, inexperienced pitcher even if he has a 3.34 ERA.

Phil Hughes will probably get the call here. Hughes has a 4.23 ERA, 4.56 FIP, and 4.35 xFIP. He’s been a slightly below league-average pitcher this year, but Baltimore’s offense is not good.

The controversial decision would be to give Nova (3.92x FIP — much better than Hughes) a short start and hand it over to the bullpen after a few innings, but only 6% of NoMaas visitors thought the self-proclaimed “best pitcher in the world” should be in the playoff rotation.

2) Wither BMG?

Brett Gardner has been a 6.2 and 5.2 WAR player in the two seasons prior to this. It’s hard to imagine a scenario where the correct play is to sit such an elite player if he’s healthy. However, we don’t really have a problem with the inevitable choice of Ichiro over BMG in left.

Gardner’s long layoff makes his effectivenesss questionable. Ichiro has been mighty fine in pinstripes. Gardner’s unique skill set makes him very useful as a pinch runner and defensive replacement (though he’d be replacing one of three quality OFs, so the leverage isn’t that great). We love us some BMG, but a bench role is a much greater possibility.

3) What if Soriano struggles?

Soriano had a great year, cementing the closer spot with a 2.26 ERA and 42 saves. But in the last four games following his two-saves-in-one-day effort, he’s had 3 K to 5 BB, and has allowed 3 earned runs in 4 and 1/3 innings. It’s obviously a super small sample size, but there are reasons for concern. The double-header double-save capped off a heavy workload for Soriano, who pitched in 67 high-leverage innings after coming off injury in 2011 (39.1 IP).

Moreover, he really wasn’t as good as his ERA to begin with. His career ERA is half a run higher, and his 3.75 xFIP suggests his true talent level might be a touch higher than that. Girardi will stick with the guy who brought him to this dance, but he should have a shorter leash. If Soriano continues to show command issues, the Yankees ought to turn to David Robertson for the highest leverage spots.

D-Rob has been among the highest level of elite pitchers for three years now, with a 2.48 ERA / 2.61 FIP / 2.92 xFIP (2010-2012) despite pitching in the AL East and in Yankee Stadium.

Decisions, decision…what do you think?
