White Sox OF J.B. Shuck pitches, retires Bryce Harper

James Shields' White Sox debut didn't exactly go as planned.

After a brutal outing (2 IP, 8 H, 7 R, 7 ER), Shields was jeered with boos as he left U.S. Cellular field.

But when one door shut, it opened a window ... er, of sorts.

One time Ohio State star J.B. Shuck, a utility player for the White Sox, isn't exactly lighting the world on fire with his pinch hitting at the moment. He's managed to cling on to his roster spot with his versatility though, and Wednesday night allowed him to put that on full display.

Trailing the Nationals 10-0, Shuck was called in to pitch for the first time ever in his major league career. Though he'd seen action in relief in the minors, Shuck hadn't pitched at the highest level after serving as a left-handed starter part-time for the Buckeyes.

Despite a tiny bit of rust, Shuck looked the part, hitting 91 mph on the radar gun and even retiring NL MVP Bryce Harper:

Shuck seemed to take the experience in stride, as he told MLB.com's Scott Merkin post game:

"I started for three years [at Ohio State]. It was an adrenaline rush. You joke around about it all the time, but you get out there and it was like all right, here we go."
