Rapid Reaction: Mets 9, Yankees 4

Two pitcher's duels and a laugher, that's what this year's Subway Series has come down to, and so far, the Yankees have been on the wrong side of all three of them.

Losing on a bad inning by David Robertson on Monday? Surprising. Watching Mariano Rivera blow his first save of the year on Tuesday? Shocking.

But there's just one word to describe this one: Embarrassing. Even Ike Davis' bat got into the act.

Right now, the Yankees are officially off the rails. Out of it before the were ever in it, Wednesday night's 9-4 loss to the Mets was the Yankees' fourth straight, their first four-game losing streak of the season and first since last July.

And you have to go back to May 15, 2011, for the last time they lost five in a row.

What it means: That having been swept in the two-game series at Citi Field, the Yankees are now halfway to being swept by the Mets at home, too, and three-quarters of the way to taking an 0-for-4 in this year's abbreviated Subway Series. Now, it's up to Vidal Nuno -- who, with Mark Teixeira, Kevin Youkilis and Andy Pettitte all slated to return from the DL soon, may not be a Yankee much longer -- to avoid that ignominy in Thursday night's series finale.

Walk-on: Yankees starter David Phelps made a cameo appearance, getting shelled for five runs (four earned) on four hits and two walks, and only getting one out before leaving the game to some lusty boos. It's possible the line drive that bruised Phelps forearm in his last outing had something to to with this, although he insisted he was fine all week. Whatever the cause, Phelps' "outing" was of a sort not seen in more than three decades; according to ESPN Stats & Info, the last Yankee pitcher to allow five or more runs while getting just one out was Rudy May. In 1981!

Cancel that trip to Vegas: Ruben Tejada and Ike Davis, both of whom were reportedly warned Tuesday night that they were soon headed to the Mets' Triple-A club in Las Vegas, figured strongly in the five-run first, Tejada doubling to lead off the game and scoring the first run on Daniel Murphy's single, and Davis lining a two-run single on an 0-2 pitch, a rare occurrence this season. Davis singled again in the fifth.

No relief:After Preston Claiborne turned in a perfect 1 2/3 innings, Adam Warren gave up three more runs, one on a solo homer by Marlon Byrd in the third and two more on a double by Lucas Duda in the fourth.

It's Brennan, not Brett: Byrd's HR might have been a long, heart-stopping out if Brett Gardner had been chasing it, because it came down right on the wide concrete top of the right-field fence and bounced into the seats. Brennan Boesch made a gallant effort but couldn't quite get the elevation necessary to pull this one back.

Brennan Bash: Boesch negated Byrd's home run with one of his own with one out in the fourth, trimming Mets lead to 8-1. It was Boesch's first home run since being recalled from Triple-A Scranton on Saturday and his third of the season.

Lineup shaken, not stirred: Joe Girardi sat down the slumping Vernon Wells (2-for-22) and David Adams (2-for-12) in favor of Boesch and Reid Brignac. Girardi got some production out of Boesch -- the solo HR in the fourth and an RBI infield single in the sixth -- but Brignac went hitless and the reshuffled batting order, with Travis Hafner batting third and Lyle Overbay at cleanup, managed just three runs. The Yankees have scored just eight runs in their last four games. All losses, of course.

Ivan, get a mop: Used in mop-up duty after the Mets had pout up eight runs on Phelps and Warren, Ivan Nova pitched well in relief, working four innings without allowing a run before weakening in the ninth, in which he allowed a run on four singles. Nova walked one and struck out six, including the side in a dominant eighth inning.

Queens high: Lots of Mets fans in the announced crowd of 43,681. The "Let's Go Mets!" chants started in the five-run first inning, and what was left of the crowd by the eighth was chanting "M-V-P," but not for Robinson Cano. For Lucas Duda.

What's next: We bid farewell to the 2013 Subway Series with the finale matching LHP Nuno (1-1, 1.93) and RHP Dillon Gee (2-6, 6.34), first pitch at 7:05 p.m.
