Let’s just say Sergio Mitre hasn’t exactly instilled confidence as a fifth starter. In three innings, he gave up seven hits, five earned runs, faced seven full counts. And threw 75 pitches.

What a coincidence that Mitre started, and departed early, on the day of the trade deadline. You have to wonder if the Yankees ultimately will regret not addressing their pitching depth before 4 p.m. today.

Or what they’ll do when Joba closes in on his innings limit — a number even he claims not to know — in six starts or so and they preemptively move him to the bullpen.

Or if, perhaps, Phil Hughes is being stretched out before our very eyes. Three of his six appearances in the second half have been for two innings. In three, he has thrown at least 35 pitches. With Aceves recently suffering from shoulder fatigue, Hughes might be the better option of the two should the Yankees need a starter.

For now, the Yankees will hope they don’t need a starter. Mitre’s next scheduled turn, by the way, is the series opener against the Red Sox at Yankee Stadium.

Shelley Duncan: He’s absolutely delighted to be here, having become resigned to spending the entire season at AAA. “I can’t tell you how happy I am,” he said between hugs from Joba and Hughes. The Yankees have another roster move to make tomorrow, however, and Girardi talked during pregame about the versatility he would gain by utilizing Ransom and Hairston. You’ve got to think the roster move will be between Duncan and Ransom.

Roy Halladay: It will be interesting to see how he reacts to not being dealt. The Yankees will be the first to find out; he pitches Tuesday against Joba at Rogers Centre. J.P. Ricciardi overplayed his hand, never actually intended to trade his ace — unless the offer was completely ridiculous — or recently got assurance from inside the Blue Jays organization that he didn’t have to make the trade. Or something else. No matter what, the situation played out very publicly — probably to a point where it disrupted the routine-obsessed Halladay.

Ozzie Guillen: He was giddy while talking to Jeter before the game. Now he’s wearing a sweatshirt as he walks to the mound. A sweatshirt. Like Belichick, except Ozzie’s doesn’t look like it was at the bottom of the laundry basket.

Michael Bolton: He’s here. Love him! “Soul Provider” is a great song. CVS sells his greatest hits for $8.99 or something like that. A tremendous bargain.
