    Scouts in the Pacific Northwest are more than familiar with Mortensen, who went to high school in Idaho and spent two seasons at Treasure Valley (Ore.) Community College. The Devil Rays drafted him in the 25th round in 2005, but he chose to go to Gonzaga instead and wasn't drafted after a disastrous 6-8, 5.89 campaign. Until this season, the gangly Mortensen was all projection and little production. His velocity took a jump (up to 92 mph) last summer in the West Coast Collegiate League, but his command remained spotty. He was shellacked at Arizona in his first start this season, but since then has had some of the best stuff in the West. Mortensen features a heavy 90-94 mph fastball with excellent sink. His secondary stuff grades as average now, with future plus grades as well: a hard slider and changeup featuring deceptive arm speed. His command is below-average. He's a senior sign with upside, though, and could go as high as the third round.
