PHILADELPHIA (Interstat) — The Penn Quakers, held hitless for eight innings, staged a stunning four-run rally in the bottom of the ninth to stun the Cornell Big Red 6-5 on Sunday afternoon at Hank DeVincent Field, completing a three-game Ivy League sweep.

The most important part of the game was the final frame, where Penn, facing a three-run deficit and without a hit since the third inning, mounted an improbable comeback against the Cornell bullpen. The Quakers sent eight men to the plate, scoring four runs on just one hit, capitalizing on three walks, two hit batters, three wild pitches and a crucial sacrifice fly to steal the victory.

Cornell, which outhit Penn 10-6, built its lead early against Penn starter Aidan von Zuben. The Big Red scored once in the first on an Owen Carlson groundout and added two more in the second on a bases-loaded walk by John L. and a fielder’s choice by Hager. They extended the lead to 5-2 in the third on an RBI single by Swidorski and a run-scoring groundout by Shin.

Penn’s offense, meanwhile, was stifled by Cornell pitching but manufactured runs with small ball. The Quakers scored in the first on a sacrifice fly by James Secretarski and added another in the second on a sac fly by Ernie Echevarria. Those were the only runs allowed by Cornell starter Ethan Hamill, who worked five hitless innings, walking three and striking out three. John Hegarty followed with three more hitless innings of relief.

The game turned with the entrance of Penn reliever Thomas Shurtleff. Entering in the fourth, Shurtleff silenced the Big Red bats, tossing six scoreless innings, allowing just four hits and striking out seven to keep the Quakers within striking distance.

In the ninth, trailing 5-2, Echevarria led off with a double against Hegarty, Penn’s first hit since the third inning. After a pitching change to Max Foster, a wild pitch and a walk put runners on the corners. Another wild pitch allowed Echevarria to score, making it 5-3. A walk and a stolen base put the tying runs in scoring position with one out.

Josh Shea entered for Cornell and got Secretarski to fly out, but Taylor stole third on the play. Pokrovsky then delivered a sacrifice fly to right, scoring Guachione to pull Penn within one. Taylor then scored the tying run on another wild pitch. After a walk re-loaded the bases, Spaventa lined a single through the left side, scoring Taylor with the winning run.

Shurtleff earned the win in relief. Foster took the loss for Cornell.

Penn improved to 13-15 overall, while Cornell fell to 6-20. The Quakers next visit Monmouth on Wednesday. The Big Red host Binghamton on Tuesday.

The comeback defied pregame projections. Interstat’s game simulator had projected a final score of Cornell 4, Penn 7, and its ELO system gave Penn a 71.80 percent probability to win.
