Behind timely power hitting and a battalion of solid pitchers, the Red Rolfe Division champion Harvard baseball team (26-16, 16-4 Ivy) avenged an earlier loss by beating UMass (22-17), 6-4, yesterday on O'Donnell Field.

Captain Hal Carey blasted two home runs at clutch moments for the Crimson and finished with four RBI on the day.

Senior Donnie Jamieson (5-0) recorded the win for the Crimson-one of eight Harvard hurlers to take the mound.

"So many people contributed today," Harvard coach Joe Walsh said.

The solid win gives Harvard important momentum going into its weekend series with Lou Gehrig Division champion Princeton to determine the Ivy title.

"Everything's working for us right now," senior catcher Jason Keck said. "Hitting, pitching and defense--it feels awesome."

The Crimson and the Minutemen met in the Beanpot semifinals last Tuesday, with UMass winning the slugfest 13-12. However, Harvard leads the all-time series 16-10 with today's win.

"Last time had nothing to do with today," Walsh said. "UMass is a real good ball club, but we didn't let them beat us today. We did a real good job."

Sophomore Mike Dryden got the start for the Crimson, giving up a run off two hits in two innings of work. UMass went up 1-0 in the second off a two-out single up the middle by Seth Kaplan.

Freshman phenom Ben Crockett came on in the third and retired the side. In the bottom of the frame, the Harvard bats came alive.

Another standout freshman, designated hitter Josh San Salvador, led off the inning with a stand-up double deep into the right field corner.

Two batters later, Carey stepped to the plate and drove a line drive home run down the left field line. The ball, still rising as it cleared the fence, curved inside the foul pole and staked the Crimson to a 2-1 lead.

"I've been feeling really good the last couple of days," Carey said. I've been hitting the ball hard and getting a lot of extra base hits."

UMass was not done, however, and answered with two runs in the top of the fourth off senior Andrew Duffell. The Minutemen got a pair of solo home runs to reclaim the lead at 3-2.

With the crucial series against Princeton approaching, Walsh rotated the Harvard staff each inning to keep his pitching arms loose.
