Joe Girardi was seething mad at Ivan Nova last night, which he revealed with his angry reaction to a question I asked about whether the Yankees were doing enough to make the 25-year-old right-hander aware of any mechanical flaws that might be affecting the location of his fastball.

You can read the details of our, er, discussion here, but suffice it to say, Girardi is frustrated with Nova, whose laid-back personality, once viewed as a sign of his unflappability, may now be being perceived as nonchalance, or worse.

His record over the past five weeks has been horrendous, his body language questionable, his pitches frighteningly hittable.

Which brings us to the Question of the Day: Is it time to swap Nova for David Phelps in the rotation?

Phelps has an admittedly small sample size as a starter, just five starts comprising all of 24 2/3 innings, but his ERA in those starts is 2.91 and his strikeouts-to-walks ratio is an impressive 26-8. Would you be in favor of removing Nova, who at one point won 15 consecutive decisions, and replacing him with Phelps, a comparative novice who shows lots of promise? Let us know below.

Up now: My column on Nova, and why he is driving Joe Girardi bananas.

Coming soon: I'll be live-chatting at noon. Link to come this morning. Also: a W2W4 by the redoubtable Mark Simon, followed by the clubhouse opening at 4:35 New York time in advance of tonight's series finale, in which Phil Hughes (12-10, 4.23) will be asked to stave off a sweep by the White Sox, facing LHP Chris Sale, who is having an outstanding season (14-4, 2.72). First pitch is at 8:05 p.m.

Check in often and, as always, thanks for reading.
