FORT MYERS, Fla. — Mike Napoli hit a solo home run Friday, his fourth of the spring, to help the Boston Red Sox defeat the Minnesota Twins, 4-0.

Napoli homered off Twins starter Phil Hughes. The ball landed on the grass-covered berm in left field.

“I got behind him a little bit,” Hughes said. “He put his head down and hit it.”

Felix Doubront of Boston made the most of his final spring training start, striking out seven and giving up two walks and seven hits in five innings. He lowered his spring ERA from 9.64 to 7.11 in five appearances.

“I have met my goals,” Doubront said. “I have the mentality set to start the season. It was a better start than the last one. In spring training I figured out a lot of things.”

Manager John Farrell said he noticed the improvement.

“I thought he used his cutter a little bit more today than he has pretty much all spring,” Farrell said. “We saw some pitching power. It was a good way to finish camp.”

Red Sox reserve Mike Carp started at first base, and had two hits with an RBI and two runs.

Shane Victorino, who has been slowed by pain on his left side, started in center field for the Red Sox and went 1 for 4.
