FORT MYERS, Fla. (AP) — Mike Napoli started a seven-run fourth inning with a broken-bat homer and Justin Masterson allowed one run in 5 2-3 innings as the Boston Red Sox rolled to a 14-2 victory over the Minnesota Twins on Monday night.

Napoli had his bat sawed off on an inside pitch from Brian Duensing. The Red Sox went on to score six more times in the inning off Duensing. Xander Bogaerts, Mookie Betts and Dustin Pedroia hit run-scoring doubles.

The outburst was some good news after the Red Sox placed catcher Christian Vazquez on the 60-day disabled list with a right elbow sprain earlier in the day. Vazquez will get a second opinion Wednesday from orthopedist James Andrews in Gulf Breeze, Fla., and could be facing season-ending Tommy John ligament-reconstruction surgery.

Masterson scattered five hits while striking out four and walking one. He had given up nine runs in 12 1-3 innings in his previous four starts.

Twins reliever Blaine Boyer made an emergency start and pitched 1 2-3 innings in place of Kyle Gibson, who had the flu.
