CHESTNUT HILL--The book on the Boston College baseball team says they like the long ball.

The Eagles (13-12, 3-6 Big East) lived up to billing yesterday, drilling seven home runs in a doubleheader sweep of the Crimson (12-12, 6-2 Ivy) at Shea Field.

First baseman Sean McGowan led a 28-run, 28-hit assault with four home runs and nine RBI. He leads the Big East with 18 on the season, and has 50 RBI and a 1.070 slugging percentage.

"I've never had a day like this before," McGowan said. "Never hit four home runs in one day before. From the start, I was seeing the ball real well, there was a good wind and I got hold of some good pitches to drive."

B.C.'s Jeff Langone hit a grand slam during a 12-run third inning in the opener, and earned a complete-game 12-6 win, while McGowan and Eagles second baseman Mike Gambino combined for eight RBI during a 16-5 romp in the nightcap.

Langone is second on the team with six home runs.

"We were definitely a little down, losing two games that weren't that close," said captain Hal Carey. "The last few innings of both of those games, we were really out of it. It's a frustrating time right now."

The Eagles big burst came in the third inning of the nightcap, when they scored seven to open up a 9-1 lead and chase freshman starter Justin Nyweide (0-2).
