THURSDAY: Krook is choosing to go to college as a result of an issue with his physical, according to Clark Spencer of the Miami Herald. The Marlins found an issue — believed to be in Krook's shoulder — which caused them to drop their offer from slot value to $650K. They will, of course, receive a compensatory pick in the 2014 draft as long as they leave their offer on the table for Krook through the July 12 signing deadline.

WEDNESDAY: Pitcher Matt Krook has decided not to sign with the Marlins and will instead attend the University of Oregon, according to Jerry Crasnick of ESPN.com (via Twitter). Miami selected Krook with the No. 35 pick which fell into the Competitive Balance Round A portion of the draft.

According to Baseball America, the suggested value of the No. 35 pick was roughly $1.588MM. Baseball America had the high school left-hander ranked as the 42nd best prospect in the draft, Jonathan Mayo of MLB.com had him at No. 55, and Keith Law of ESPN.com was higher on him and had him pegged at No. 30.

BA notes that the 6-foot-4, 195-pound southpaw has had consistency issues as of late. At his best, Krook sits at 90-92 mph, touches 95, and shows flashes of a hard curveball. However, he doesn't have a changeup and there is some effort to his delivery.
