HAMDEN, Conn. — Dartmouth continued its historic start to the 2013 season with a 9-4 victory at Quinnipiac on Wednesday afternoon, improving to 15-3 on the season. Junior Ryan Toimil broke a 2-2 tie in the sixth with a sacrifice fly and the Big Green scored three runs in each of the seventh and ninth innings to seal the victory over the Bobcats (9-12).

Dartmouth, which has won 15 of its first 18 games for the first time in over 140 seasons of varsity baseball, collected 10 hits against five Quinnipiac pitchers. Junior Jeff Keller, who leads the nation in doubles per game and yesterday was named the Ivy League Player of the Week, added two more two-baggers to his ledger, junior Dustin Selzer and freshman Adam Gauthier also contributed a pair of hits, and senior Ennis Coble added a two-run homer, his first of the season.

The Big Green got the bats going in the second inning, beginning with a one-out double to the gap in left-center by Selzer. A wild pitch sent him to third, and a walk to Toimil put runners on the corners before another wild pitch allowed Toimil to advance to second. Gauthier then delivered his first collegiate hit with an RBI single to center, and classmate Trent Goodrich hit a grounder that brought home Toimil for a 2-0 lead.

Junior right-hander Louis Concato retired the first eight Bobcats before yielding a two-out double in the third to Steffen Herter, who then scored on a Brian Ruditys single to center to cut the Dartmouth lead in half.

In the fifth, Quinnipiac chased Concato when it tied the score with an unearned run. Herter reached on a two-base error to lead off the inning, went to third on another Ruditys single and scored on Vincent Guglietti’s single to center. Junior Mike Dodakian relieved Concato and retired the next two hitters to preserve the tie score.

Dartmouth retook the lead for good in the sixth as Keller hit his first two-bagger of the day, advanced to third on a Selzer single and scooted home on Toimil’s fly to center.

The Bobcats brought on their third pitcher of the afternoon to start the seventh in Kevin O’Connell, who immediately hit sophomore Matt Parisi with a pitch. His wildness continued as he walked sophomore Bo Patterson, and following a sacrifice bunt by Coble, sophomore Nick Lombardi stroked a two-run single to center. Keller then laced another double to right, scoring Lombardi all the way from first base for a 6-2 advantage.

Coble cranked his two-run homer in the ninth off reliever Kevin Castodio after Patterson had bunted for a single. Toimil drove in the final run with a two-out single to the opposite field in left, allowing Lombardi to score after he had walked earlier in the stanza.

Quinnipiac scored two unearned runs in the ninth thanks to an error and a passed ball, but Dartmouth was able to record the final out thanks to that passed ball. With runners on second and third, the pitch got away from Gauthier, who vainly attempted to get the runner coming from third. His throw caromed off the runner and was tracked down by freshman reliever Beau Sulser, who threw to Selzer who was covering the plate from his position at first base. Selzer applied the tag to the runner that was trying to score from second to end the game.

Earning the victory was Dodakian (1-0), who hurled 2.2 scoreless innings of relief, surrendering three hits with one strikeout. The four Big Green pitchers gave up 14 hits but just one walk and left 11 Bobcats on the bases to help limit the damage.

The second Bobcat pitcher of the day, Kyle Musco (0-1), suffered the loss as he yielded the go-ahead run in the sixth. It was the only run he allowed in three innings on the mound on two hits with a pair of punchouts.

Dartmouth returns home this weekend to host Princeton (5-18, 3-1 Ivy) and Cornell (15-7, 3-1 Ivy) in Ivy League doubleheaders. Saturday’s twinbill against the Tigers will be a seven-inning game at noon followed by a nine-inning contest, while Sunday’s double dip against the Big Red will start off with a nine-inning game at noon followed by a seven-inning contest to accommodate the Fox College Sports television broadcast of the opener.
