FOXSports.com is reporting that DIamondbacks pitching prospect Jarrod Parker will have Tommy John surgery next week.
Parker, 20, combined to go 5-6 with a 3.14 ERA in 20 starts at Single-A and Double-A last season.
The timetable for Tommy John surgery is around 10-12 months, meaning he may not be ready until the 2011 season.
How does this impact his future?
