HANOVER, N.H.—Entering the final weekend of the regular season, only Brown stood in the path of the Harvard baseball team’s journey to the Ivy League championship series.

Today, the weekend is over and nothing has changed.

Harvard split a home-and-home doubleheader against Dartmouth this weekend, forcing a one-game playoff with Brown that will determine the winner of the Red Rolfe Division. Both Harvard and Brown are 13-7 in the Ivy League. The winner of Wednesday’s playoff will play Princeton in a best-of-three series this weekend.

“We’ll be ready for Brown on Wednesday,” Harvard coach Joe Walsh said. “It’s a shame we couldn’t wrap it up this weekend, but we have another ballgame to play that we can win.”

Harvard began the weekend with a one-game lead in the Ivy League over Brown. Brown won three of four games against Yale in back-to-back doubleheaders on Friday and Saturday, placing Harvard in a position to win the Red Rolfe Division with two victories at Dartmouth on Sunday. Harvard won Game One, clinching at least a tie, but could not get the sweep, falling 4-3 in game two.

With the Red Rolfe Championship in the Crimson’s reach, Dartmouth freshman closer Nick Peay shut the door in the eighth and ninth innings, ruining Harvard’s hopes of winning the division outright this weekend.

Harvard jumped out to a 2-0 lead in the second inning. Senior Javy Lopez led off the inning with a base hit to center and scored on senior Josh San Salvador’s 380-foot double to left-center. Senior Chaney Sheffield drove in San Salvador with a sharp one-out single to left.

Dartmouth responded with three runs off of Harvard’s Game Two starter, sophomore Trey Hendricks, in the bottom of the third.

Dartmouth sophomore Cooper Chapin drove in senior Matt Klentak with an RBI single to center to score the Big Green’s first run of the game. Chapin and junior Jason DaCosta scored two batters later when clean-up hitter Mike Miluesnic roped a two-run double to left-center, giving the Big Green the lead.

“We have a lot of confidence in Trey,” Walsh said. “I thought he pitched well. He’s a legitimate weekend starter, but we didn’t help him with the bats.”

Dartmouth stretched the margin to two runs in the bottom of the fifth and took the 4-2 lead into the seventh when Harvard got one back.

Senior second baseman Faiz Shakir’s single scored Sheffield to cut the lead to one. Harvard’s momentum continued in the bottom half of the seventh, when junior Kenon Ronz got out of a bases-loaded jam, striking out Josh Cushman to end the inning.

In the eighth, senior third baseman Nick Carter crushed a one-out double to right-center, putting the tying run in scoring position. For a brief moment, it looked as though Harvard would tie the game when San Salvador ripped a line drive down the left field line. Unfortunately for the Crimson, Dartmouth’s third-baseman Eddie Lucas was in perfect position to catch the liner, allowing Dartmouth to get out of the inning unscathed.
