Scouting grades: Fastball: 50 | Curveball: 55 | Slider: 65 | Changeup: 50 | Control: 50 | Overall: 50

Eyanson served UC San Diego as a solid starter for two seasons before electing to transfer to LSU. He showed top-two-rounds potential last summer by working with a 93-97 mph fastball and a hammer curveball while with the U.S. collegiate national team and in the Cape Cod League. His stuff wasn't as sharp early in his junior season but he came on strong in the final two months to rank third in NCAA Division I in wins (12) and strikeouts (152 in 108 innings) and help the Tigers win the College World Series.

Eyanson's slider has become his best pitch during his first season in Baton Rouge, parking at 82-85 mph and eliciting empty swings in and out of the strike zone thanks to its tremendous depth. His upper-70s curveball has been solid but hasn't enticed hitters to chase nearly as much as his slide piece has. His fastball has operated at 92-94 mph and topped out at 98, though its lack of life can make it vulnerable if he doesn't locate it well.

Though Eyanson's low-80s changeup can miss bats with its fade and sink, he struggles to throw it for strikes. He's a good athlete with decent control but will nibble around the plate too much at times. He has a ceiling of a No. 3 starter if he can improve his fastball shape but also could wind up as a reliever who relies heavily on his breaking pitches.

Eyanson served UC San Diego as a solid starter for two seasons before electing to transfer to Louisiana State. His stuff wasn't as sharp early this spring, but he came on strong in the final two months to rank third in NCAA Division I in wins (12) and strikeouts (152 in 108 innings) and help the Tigers win the Men's College World Series. The Red Sox were able to float him down to the third round of the Draft, where they signed him for nearly double slot value at $1.75 million.
