Oregon baseball starting pitcher Matt Krook will undergo Tommy John surgery on his throwing arm Tuesday and will miss the rest of his freshman season, the university announced Monday afternoon. James Andrews will perform the surgery.

The left-hander had a 1.79 ERA and threw a Pac-12-leading 56 strikeouts before leaving Oregon’s game versus Washington with an elbow injury on April 5.

Krook received an MRI on his elbow 10 days ago but he and the team wanted a second opinion before deciding which course of action to take.

“As a pitcher, you kind of think you’re almost a ticking time bomb,” Krook said. “Everybody nowadays has to get something done. It’s unfortunate, but it’s what you sign up for.”

Krook is Oregon’s second left-handed starting pitcher to receive Tommy John surgery in the last two months. Cole Irvin underwent the procedure before the season and he, like Krook, will not return until 2015 at the earliest.

The Miami Marlins drafted Krook with the 35th overall pick in last year’s MLB draft, but they reduced their offer after he failed his physical (MRI results revealed a slight labrum tear). Krook was close to signing with the Marlins before the reduced offer but switched course and decided to play for the Ducks.
