Sonny Gray failed to make it past the fourth inning for the second time in three starts this season in Thursday's 6-3 loss to the Boston Red Sox at Fenway Park.
Gray (1-1) surrendered six runs, seven hits and two walks in three innings as New York fell to 6-7 and lost for the fifth time in its last seven games.
"I just didn't execute very well," Gray said after the game, according to the New York Daily News' Mike Mazzeo. "It just made it hard all the way around."
In seven career starts against the Red Sox, Gray is 1-5 with a 5.97 ERA. He is 0-3 with an 8.66 ERA in four starts at Fenway Park.
The 28-year-old right-hander, whom the Yankees acquired from the Oakland Athletics last July, gave up four runs in the second inning on a Sandy Leon single, Mookie Betts sac fly, Andrew Benintendi fielder's choice and Mitch Moreland RBI single. An inning later, Jackie Bradley Jr. hit an RBI ground rule double to left and scored on a Betts fielder's choice.
"A couple of walks and a couple of bloop hits and the next thing you know, you can give up four runs pretty easily," Gray said, according to the New York Post's Dan Martin.
Gray has only pitched past the fourth inning once this season -- a six-inning, three-run performance on April 7 against the Baltimore Orioles. Last year, he had four starts when he didn't pitch five complete innings.
"We know what he's capable of, but tonight wasn't his night -- whether he was falling behind or struggling to put guys away," manager Aaron Boone said, according to Mazzeo. "Tonight it just wasn't there."
