Freshman Sam Cohen slugged a pinch-hit, walk-off grand slam homer in the bottom of the ninth inning to give UC Santa Barbara a dramatic 4-3 victory over Louisville and earn the school's first College World Series berth.
The left-handed-hitting Cohen lined a pitch from Cardinals right-hander Zack Burdi over the right-field wall with one out in the ninth to stun the crowd at Louisville's Patterson Stadium. It propelled the Gauchos (42-18-1) to their second straight win over the Cardinals in the best-of-three super regional series.
Louisville (50-14), the No. 2 national seed, took a 3-0 lead into the ninth, and Burdi retired the first batter before the Gauchos rallied. J.J. Muno singled, and the next two batters walked before Cohen was called on as a pinch hitter.
Cohen had batted just 26 times all season -- with one homer -- before sending a 1-2 pitch inside the right field foul pole and setting off a raucous celebration at home plate.
The Cardinals had stymied UC Santa Barbara until the ninth. Drew Harrington struck out a career-high 12 in seven scoreless innings, and Louisville scored three runs in the fourth on Brendan McKay's two-out homer, Blake Tiberi's run-scoring double and Danny Rosenbaum's RBI single.

Michelangeli hit a three-run homer in the second inning and a grand slam in the seventh for the Hurricanes (50-12). His celebration of the grand slam nearly sparked a benches-clearing brawl between the two Atlantic Coast Conference programs before the umpires restored order.
The Eagles (35-22), who won Saturday's contest of the best-of-three super regional, were trying to reach the College World Series for the first time in 49 years.
