Jason Vargas picked a bad night to roll out his first shaky start of the season Monday, when the Mariners' offense provided almost no help in a 6-1 loss to the Red Sox at Fenway Park.
Boston southpaw Jon Lester held Seattle scoreless until Kyle Seager's RBI grounder with one out in the ninth inning as the reviving Red Sox won their fourth straight to improve to 16-19. It was Lester's eighth complete game of his career, as he allowed eight hits, but no walks.
Vargas, who came in with a 2.79 ERA and an outstanding 0.97 WHIP through eight starts, gave up a pair of home runs and two doubles among seven hits in the first four innings.
The 29-year-old's normally potent changeup abandoned him, leaving the southpaw one-dimensional in a park where all weapons are needed.
"I really didn't have anything but a fastball," Vargas said. "It was kind of opposite from my last outing, where I really couldn't throw a changeup for a ball. And all of them tonight were balls. It was just one of those nights where I had to go out there and battle.
"My fastball was a fastball, but if I missed with it, they were doing damage, because they didn't have to worry about any other pitch. It was just a grind."
Vargas dug in and wound up allowing just those seven hits over six innings, but the five runs and two homers were both season highs, and three walks equaled his high there as well. Vargas is now 4-3 with a 3.28 ERA, with all three losses coming on the road.
