HANOVER, N.H. — Dartmouth tied a school record with four triples to subdue the visiting Saint Anselm Hawks on Tuesday afternoon at Red Rolfe Field at Biondi Park by a 5-1 score. Freshman Jeff Keller tied another school record with two of those three-baggers and added a double to help the Big Green improve to 19-10 on the season and end a four-game skid, while Saint Anselm dropped under .500 at 16-17.

Not only did Dartmouth extend its home winning streak to 17 — the second longest in the country — it also upped its total of triples on the season to 21, breaking the school record of 20 set just last year. In each season since the ball park was renovated in 2009, the Big Green have broken the triples record, stroking 19 in 2009 as well.

Trailing 1-0 in the fourth inning, the Dartmouth bats showed some life when senior Jeff Onstott and Keller hit back-to-back triples to tie the game. Hawk starter Timothy Cooney managed to strand Keller at third, however, when he got a pair of easy grounders to first base.

After that Keller triple, Cooney retired the next eight hitters until Keller led off the seventh by ripping a double into the gap in left-center. Sophomore Chad Piersma moved Keller along by pulling a grounder to second, and junior David Turnbull brought him home with a line single over the shortstop, giving Dartmouth its first lead at 2-1.

When Saint Anselm went to the bullpen to start the eighth, the Big Green took advantage by scoring three insurance runs. Senior Sam Bean dropped a bunt down the third-base line for lead-off single, and one-out later, senior Jason Brooks boomed a triple off the fence in deep center. After sophomore Ennis Coble walked on a full-count pitch, Onstott lofted a fly ball to right with Brooks just sliding in ahead of the tag. Keller then hit his second triple to bring home the final run.

Things got a bit interesting in the ninth when the Hawks loaded the bases with nobody out against closer Ryan Smith. But the senior was up to the task, punching out the next two hitters before a routine grounder to second to end the game.

Dartmouth got fine performances on the mound as sophomore Michael Johnson allowed just one run on four hits and a pair of walks in his five-inning start while striking out a season-high five batters. Senior Dan Ternowchek (1-1) came on to start the sixth and hurled three no-hit innings to earn the victory.

Cooney (0-4) was the tough-luck loser for Saint Anselm, surrendering just two runs over seven innings on six hits and two walks with three strikeouts.

Keller finished the day 3-for-4 for the Big Green with his double and two triples, scoring once and driving in two runs. On the bases, Dartmouth stole a season-high five bases with Coble swiping a career-high three himself.

Dartmouth puts its home win streak on the line again tomorrow when Hartford comes to town for a game at 3 p.m.

Notes: In each of the last three meetings with Saint Anselm, a Big Green batter has hit two triples in the game. Two years ago, Joe Sclafani performed the honors, while Brooks stroked two in last year’s game. Keller is the 20th player in Dartmouth history to accomplish the feat.
