HANOVER, N.H. — Senior Cole Sulser threw a three-hit shutout in the opener and freshman Joe Purritano had six hits in the two games, including two homers and a triple while driving in five runs in the nightcap, to lead host Dartmouth to a sweep of the Brown Bears on Saturday afternoon by scores of 2-0 and 11-3 at Red Rolfe Field at Biondi Park. Sophomore Matt Parisi was a perfect 5-for-5 with three doubles in the second game as well for the Big Green (20-6, 6-4 Ivy) as Brown fell to 3-22 on the season and 1-9 in Ivy League play.

Sulser was on his game right from the start as the right-hander retired the first nine batters of the game. His offense provided him the only run we would need in the bottom of the third when junior Jeff Keller lined a two-out single to left, allowing sophomore Bo Patterson — who had singled to lead off the inning — to trot home from third for the 1-0 lead.

In the fourth, Sulser found trouble when the Bears loaded the bases with one out on two singles and a walk. But he kept his composure and got called third strikes on each of the next two Brown hitters, escaping with the 1-0 lead intact.

That lead seemed as if it would not hold up in the fifth when Tim McKeithan led off with a single and went to third when J.J. Franco’s sacrifice bunt was thrown down the right-field line, putting runners on the corners with nobody out. Again Sulser remained calm, and after a visit from his head coach, Bob Whalen, he sliced the corner for a called third strike and the first out of the inning, then induced a grounder to third that sophomore Nick Lombardi sent around the horn for the inning-ending double play.

Sulser (3-2) would not allow another base runner as he retired the side in order in both the sixth and seventh to finish his first career shutout. In his seven innings of work, he surrendered just three singles and a walk while matching a season high with eight strikeouts.

Dartmouth gave Sulser an insurance run in the last half of the sixth when Keller was hit a by a pitch, took third on a Lombardi single and came home on a single by Purritano.

Anthony Galan (1-3) was the tough-luck loser, yielding two runs on eight hits over six stanzas with six strikeouts. He could not solve Purritano, however, who was 3-for-3 with a double and an RBI to lead the offense.

In the second game, the Big Green bats wasted little time in giving senior southpaw Kyle Hunter a lead. Parisi started things with a single and senior Ennis Coble bunted for a single before Keller boomed his league-leading 18th double over the center fielder’s head to score Parisi. A hit batter loaded the bases and Lombardi followed with an RBI single between short and third. One out later, Brown hurler Kevin Carlow uncorked a wild pitch to give the Green a 3-0 lead.

The Bears bit back in the second, however, after stranding two runners in the first. Wes Van Boom lined a one-out single to right-center and Franco walked with two down to put two on for Will Marcal, who hit a 2-2 pitch high off the fence in left for a two-run double to close the gap to one run.

Dartmouth chased Carlow in the second, however, as Patterson led off with a walk and sprinted home on Parisi’s first double of the day, a line shot into the left-field corner. Carlos got the first out on strikes, then the Bears decided to intentionally walk Keller, who is among the top 10 nationally in slugging percentage. Junior Dustin Selzer hit a ball to the hole for an infield hit that loaded the bases, but Carlow got another punchout for the second out. But he threw another wild one, allowing one run to score, then Purritano ripped a two-run triple to the left-center gap to chase Carlow (0-5), whose final line included seven runs in 1.2 innings, and put the Big Green up, 7-2.

Purritano extended the lead to 9-2 in the fourth with a two-run blast to right just over the yellow tape, scoring Lombardi who had singled. Parisi added another RBI double to make it a 10-2 contest.

Hunter (3-1), meanwhile, settled into a groove and retired 13 of the last 15 hitters he faced. In six innings of work, the left-hander gave up two runs on five hits and a pair of walks while fanning five to earn his second straight victory.

In the eighth, Purritano touched Taylor Wright for a solo shot, his third homer of the season.

Junior Mike Dodakian came on to start the seventh and tossed the final three frames to earn his second save of the year, yielding just a harmless run in the ninth before getting a double play to end the game.

The two teams will square off again on Sunday at noon in another doubleheader at Red Rolfe Field at Biondi Park.

Notes: The last Dartmouth hitter with five hits in a game was Joe Sclafani ’12, who collected five against UMBC on March 24, 2011 … the last Big Green hitter to smack two homers in a game was Selzer last year against Columbia on April 8 … Parisi was left on deck in the eighth with a chance to tie the school record of four doubles in a game, set in 1926 by Al Fusonie ’28 and matched in 1943 by J.J. Curren USN.
