Purdue Fort Wayne’s Justin Osterhouse has historic day with four homers, walk-off grand slam — and a win on the mound

Justin Osterhouse has historic day with 4 homers, walk-off grand slam — and a win on the mound

One of the most insane performances in college baseball was just delivered by Purdue Fort Wayne’s Justin Osterhouse. 

Wright State has been dominant all season in the Horizon League, currently in first place. On May 15, Purdue Fort Wayne faced the Raiders in a three-game series to end the regular season, and in Game 1, the team was down 17-10 entering the bottom of the ninth inning.

Purdue Fort Wayne scored 11 runs in the bottom of the ninth to defeat the first-place Raiders.

Eight players got a hit in the bottom of the ninth, setting the situation to be 17-17 with the bases loaded. Osterhouse then stepped up to the plate and hit a walk-off grand slam over the left field wall for the win.

That was just the exclamation point to his record-setting day. His grand slam was actually his fourth homer of the game — the first player in program history to ever hit four homers in a game. He set a school record with 17 total bases, had 8 RBI and went 5 for 6 with a stolen base.

But get this — he also picked up the win on the mound. Osterhouse entered the game to pitch in the top of the ninth and threw a scoreless frame. It was his first win on the mound and just his second ever career appearance. 

How often do you see a player hit four home runs in a game, hit a walk-off grand slam and get the win? Take a bow, Justin Osterhouse.
