Stanford ace Cal Quantrill will undergo Tommy John surgery and miss the remainder of the 2015 season.
The preseason All-American and member of the Golden Spikes Award preseason watch list was 2-0 with a 1.93 ERA in three starts this season.
His father, Paul Quantrill, pitched 14 major league seasons with seven teams, including six with the Toronto Blue Jays, three with the Boston Red Sox and two more with the New York Yankees.
Quantrill spent much of his time in the clubhouse with his dad and learned how to hit from Carlos Delgado and Shawn Green.
Quantrill was the Pac-12 Freshman of the Year last season. He also pitched for the Canadian national junior team.
He was drafted by the Yankees out of high school but chose to attend Stanford. He's a projected first round pick in 2016.
The time frame for Tommy John surgery is between 12-16 months, so he's likely to miss the beginning of his junior season as well.
It won't matter if he's given a medical redshirt, the talented pitcher will likely sign following the 2016 season.
