•HIGHLIGHTS: David Ortiz made his PawSox debut and wowed the standing-room-only crowd of 11,460. The Red Sox slugger went 1-for-3, the hit being a solo home run, and a walk. Not to be outdone by Ortiz, PawSox starter Edgar Martinez improved to 4-1 with a solid 6 1/3 innings outing. He allowed three runs on four hits with two walks and five strikeouts. … PawSox starter-turned-reliever Justin Masterson worked 1 1/3 innings and surrendered two runs on two hits.

•KEY OF THE GAME: Pawtucket erupted for seven runs in the fourth inning off Toledo starter Virgil Vasquez. Ortiz led off with a solo home run, while teammates Jeff Bailey and George Kottaras belted a pair of two-run homers for Pawtucket. PawSox’ Gil Velazquez contributed a two-run single. Pawtucket batted around that inning and Ortiz made the third out with a soft liner to first during his second at-bat of the inning.

They said it: “It’s phenomenal,” said Pawtucket manager Ron Johnson of Ortiz’s impact in the clubhouse. “We’re teachers here. Whether it’s a higher level or not, we’re still teaching. This is about guys getting a firsthand experience on, not only the playing part, but what it’s going to be like when they go into that atmosphere in Fenway Park’s clubhouse. We’ve got probably one of the biggest clubhouse-atmosphere controllers here with us in David Ortiz. It’s good for the young players to be around him, and it’ll be good for guys to be playing in the game with a guy like that. He’s a guy who is your future teammate, if you get to where you want to get to”
