Brookline has evolved from a team that was reliant on home runs early in the season to one that is opportunistic and focuses on putting the ball in play, and is now reaping the benefits.

The Warrior offense made consistent contact last night at Warren Field and had only one strikeout while peppering Charlestown pitchers with 13 hits, including one homer, to lead to a 13-1 romp.

"We did a good job of putting balls into play and when you do that, you're going to score runs," head coach Jim Wulfson said.

Charlestown took a second-inning 1-0 lead but it didn't stand up very long. Patrick Webler's RBI single and Matt Weinstein's RBI double gave Brookline's under-12 Bay State team a 2-1 advantage in the bottom of the inning that it would continue to build on.

The bottom of the third inning saw the Warriors bat around as they tallied six hits and seven runs, but a key play was Deven Yee going from first to third on an Alex Chin single. This set the Warriors up with runners on second and third with no outs in the inning. Yee would also hit a two-run triple in the same inning to extend the Brookline lead to 9-1.

"Our aggressive base running really put the pressure on them," Wulfson said.

Webler's three-run homer to right in the bottom of the fourth brought the score to 13-1 and ended the game by mercy rule for Brookline. But Wulfson wanted to give the Brookline pitching credit as well. Jonas Webler worked three innings of one-run ball and Stewie Silvestri added a scoreless frame for the Warriors.

"Jonas is our ace," Wulfson said. "He throws strikes like no one I've ever seen at this level because he consistently gets into 1-2 counts."

The lopsided win gives Brookline a 4-1 record in the third round of trophy play. The Warriors will play South Boston on the road Thursday at 5:30 p.m. Brookline won easily in its first two games against South Boston, but had to squeak out an 11-10 win last Tuesday night.

"We're playing much better baseball now than we did a week ago," Wulfson said.

Wulfson's team will give its best effort to win a third-round gold trophy this weekend in Cambridge. The third-round medal games will start Saturday but game times have yet to be announced.

"We got a silver trophy in the first round and to end the season with a gold trophy in this round would put an icing on the season," Wulfson said.
