Lackey struck out two and walked none. In nine combined innings this spring, Lackey has not allowed a run — earned or unearned — or issued a walk. He has given up just five hits.
"I'm throwing the ball pretty well," said Lackey, who threw 28 of his 39 pitches for strikes. "But honestly I'd probably like to maybe give up a couple runs. Don't want to bring them all north with me."
Red Sox manager Terry Francona is pleased with Lackey's performances this spring.
"First-pitch strikes; that was fun to watch," Francona said. "Let them put it in play. Threw his breaking ball for strikes. He threw everything for strikes, down in the zone. Runner defense worked. It was fun to watch.
Mets right-hander Mike Pelfrey nearly matched Lackey's outing, going four innings, giving up one run on four hits with two strikeouts and no walks.
"I thought it was a real positive outing," Pelfrey said. "I located the fastball. I didn't get a lot of ground balls, but the sinker started sinking again. That's a good sign."
Pelfrey, who threw 66 pitches, 44 for strikes, is developing confidence in his secondary pitches.
"I feel good," he said. "I think the thing about it is I'm able to throw (the splitter) for a strike. I feel like I can throw it at any time, which is good."
The Red Sox took a 1-0 lead into the eighth, but New York's Fernando Martinez hit his third home run of the season, a three-run shot off Ramon S. Ramirez. Ramirez gave up four runs on two hits and three walks without recording an out.
Elmer Dessens pitched a scoreless ninth for the Mets.
