The Washington Nationals swept the three game series against the Diamondbacks, with a decisive 9-2 skinning of the rattlers on Sunday afternoon at Nationals Park. The victory followed a thrilling 5-2 win on Saturday. The Nats have now won eight in a row and will get a day off before embarking on a semi-extended road trip. In both of the last two games an otherwise shakey starting rotation provided consistent outings — with Garrett Mock beating Dan Heren on Saturday and J.D. Martin besting Yusmeiro Petit on Sunday. It was both Mock and Martin’s first major league victories. Mock and Martin were not overpowering, but they were good enough to allow Nats’ interim manager Jim Riggleman to mix-and-match a bullpen that had been putting in extra innings. The Nats bats continue to heat up: Adam Dunn hit his 30th home run on Sunday, Ryan Zimmerman went 3-5, and Alberto Gonzalez seems to be rediscovering his swing — he went 2-4 on Sunday.

The bats of Dunn, Guzman, Zimmerman, Morgan and Willingham — at the heart of the Nats’ order — figured big in both games: accounting for six of Washington’s eight hits on Saturday and nine of 16 hits on Sunday. But the key to Washington’s sweep of the Diamondbacks may well have been Elijah Dukes, who notched ten RBIs of a total of 21 runs the ballclub scored. Dukes unlikely resurgence makes up, at least in part, for the departure of Nick Johnson to the Marlins. Equally impressive was the Nats’ newest find: reliever Jorge Sosa. The former Braves, Cardinals and Mets journeyman pitched 2.1 innings on Sunday, which followed a one inning no-hit-no-run relief effort on Saturday. It’s clear that the deceptive Sosa has found a place at the back of the Nats’ bullpen. He may even vie, at some point, with Mike MacDougal for the closers’ role.

Why are the Nats suddenly playing so well . . .? The answer seems obvious: good pitching, timely hitting, good defense. All that. For sure. But then, you know (and, I mean, this is just a suggestion) it’s pretty hard to ignore the role played by this guy:

Down On Half Street: The Boston Globe is reporting that the Boston Red Sox, reeling from their slapping at the hands of the New York Gothams, have reportedly put a claim in on Nationals’ shortstop Cristian Guzman, who has been placed on waivers. The Nats can either pull Guzman back, let him go, or work out a deal sometime in the next 48 hours. The Red Sox have had trouble filling their hole at short — Julio Lugo is gone to St. Louis and Jed Lowrie is on the DL . . . I haven’t met a Sox fan yet who isn’t absolutely ecstatic about getting rid of Lugo: “thank God he’s gone,” they say. And you can see why. I mean, his replacement (the aforementioned) is like ”the second coming” of the second coming: except that he’s hitting .143. Oh no, what will they do without him? . . . Hey, maybe they should trade Clay “can miss” Buchholz (ERA: 5.33) and a boatload of other “can’t miss” players for Roy Halladay, who’s only the best pitcher in baseball . . ..  Nahhhhhh .   

We are pleased to announce that there’ll be a twenty minute special report on Lowrie’s status on Boston Red Sox ”Baseball Tonight,” right after the fifteen minute special on David Ortiz (which follows the sixteen minutes on the Bosox vs. the Bronx series, which is the single most important baseball series this year — not counting the Angels-Rangers tilt going on right now too, of course), so be sure to stay tuned for that compelling report . . . and, oh yes, later on in the program, we’ll be presenting our special segment, “that’s not television, that’s boring”  . . . speaking of the DL. It could be bad news for Nats’ starter Jordan Zimmermann, who is experiencing continued elbow soreness. He is scheduled to have x-rays of the elbow examined further on Monday by the nation’s leading baseball orthopedist Dr. James Andrews. Andrews isn’t examing the elbow, mind you, he’s so good all he needs to do is look at the x-rays. In any event, this is not good news . . . but hey, here’s my question and it’s damned important: do you think that Joba Chamberlain should stay as a starter, or go back to the bullpen? huh? huh? huh? do ya? do ya? do ya? . . .
