BOSTON -- D-backs right-hander Zack Greinke had to think about it for a minute before he was able to answer whether Sunday's 16-2 loss to the Red Sox at Fenway Park was the worst start of his Major League career.
Greinke (11-4) was battered by Boston, allowing nine runs on 10 hits in lasting just 1 2/3 innings.
"They just hit everything he threw up there," D-backs manager Chip Hale said.
For the record, Greinke has always thought his June 10, 2005, start against the D-backs in Arizona to be the worst of his career. He allowed 11 runs on 15 hits in 4 1/3 innings in that game for the Royals. Sunday, though, may surpass it.
"I always considered my Arizona outing my worst one," Greinke said. "But here, maybe it happened so fast I didn't really realize how bad it actually it was, but it definitely can be compared with it."
The Red Sox scored a pair of runs in the first on a homer by Mookie Betts, one of three he would hit in the game, but it was the second inning when things really got ugly.
Greinke gave up seven runs in that frame, three of which came on another Betts homer, before Hale finally removed him.
"Just seemed like my stuff was really flat today," Greinke said. "Most of the time, guys don't hit my offspeed very good, but they hit all my offspeed pitches today. I gave up a home run on a changeup, slider and curveball. Also a base hit on all those pitches. Two hits on curves, two hits on changeups, one hit on sliders, and usually I can rely on getting outs on those pitches."
The blowout loss capped a disappointing weekend in Boston in which the D-backs were unable to carry over any momentum from their three-game sweep of the Mets in New York.
"It's one of those days you deal with," Hale said. "That's our ace, that's our No. 1 guy, and they got him. They got the better of him today."
