Blue Jays embarrass the Red Sox

 So much for building up some momentum.

The Red Sox were riding a wave of good vibes after battering around the Rangers’ pitching staff, but those vibes descended this weekend against the Blue Jays’ AL-best pitching staff.

The Sox scored a grand total of five runs in two games and yesterday fell to Toronto righty Shawn Marcum and the Jacking Jays by a 15-4 score at Fenway Park.

The Sox also allowed a season-high 22 hits — and a Blue Jays franchise-record 10 doubles — and looked exactly like a team shouldn’t when its No. 1 starter is toeing the slab.

While the silent bats — absent a Kevin Youkilis solo homer in the bottom of the fourth inning and a Dustin Pedroia bomb in the bottom of the seventh — were certainly an issue, a larger concern is the continued inconsistency exhibited by one Josh Beckett.

“It looked like everything [the Blue Jays] hit against him they hit hard, but I don’t think there is a guy in this clubhouse who wouldn’t want him back in there tomorrow,” Sox outfielder Jason Bay said. “That was just [a bad day] for him. Josh Beckett is one of those guys where you get excited with him on the mound, and you think it’s going to be a good game.”

The 28-year-old flame-thrower turned the gas on high his last time out against the White Sox and looked every bit his Big Game Beckett self, but he once again stumbled to put another quality outing in back-to-back starts.
Beckett still charges out to the mound with the 96 mph fastball and a knee-buckling curve, but the nuclear stuff hasn’t added up to another vintage season.

The opponent’s batting average is more than 20 points above his career mark, and Beckett is on pace to allow more hits than innings pitched for the first time in his career.

He’s already let up as many home runs as he did all of last season and the Sox have an ace who’s not living up to his advanced billing.
