VESTAL, N.Y. - Senior center fielder Tommy Reifler ripped a first-pitch RBI single through the right side to cap a two-run rally and give Binghamton baseball (5-9) an 8-7 10-inning, walkoff win over visiting St. Bonaventure (4-10) in BU's home opener Tuesday afternoon at the Bearcats Baseball Stadium.

The game-winning hit ended a wild 3+ hour affair that included five ties, five lead changes and 37 combined players used and featured BU's first home walkoff since last March. 

Down 7-6 after the Bonnies scored a go-ahead run in the top of the 10th, BU rallied for the second straight do-or-die inning. Senior first baseman Andrew Tan and freshman infielder Todd Abraham reached base on successive St. Bona infield errors. After a strikeout, a wild pitch advanced both runners and Tan came around to score on a throwing error by the St. Bona catcher. After a groundout moved Abraham to third, Reifler delivered his game-winning hit. 

After a quiet first three innings finished with BU up 1-0, the teams scored runs in six of the last seven innings and traded blows by matching single-run innings three times. 

St. Bonaventure erased a 3-2 BU lead with a three-run home run in the sixth inning to forge ahead 5-3. But Binghamton clawed back to tie it with two runs in the bottom of the seventh on RBI singles by senior second baseman Isaiah Corry and senior outfielder Logan Haskell. In the ninth, the Bonnies pulled ahead 6-5. But BU answered again in the bottom of the frame, sending the game to extras. With one out, BU coaxed four straight walks, the last of which tied the game at 6-6. A fielder's choice putout at the plate and ensuing bases loaded strikeout prevented BU from walking it off in the ninth.     

Reifler wound up 2-for-4 with the winning RBI. Tan belted a solo home run in the second inning, his first of the season, and finished with 2 RBI. Senior outfielder Christian Perez and junior catcher Evin Sullivan had two hits apiece. 

Binghamton used seven pitchers by design and got two shutout, 1-hit innings from freshman starter Hayden Tarsia and other clean 2.0 innings from freshman Jackson Mitchell in the seventh and eighth innings. 

The Bearcats stay at home and will welcome America East foe NJIT to the Stadium for the conference-opening weekend series, which begins Friday afternoon.
