Scouting reports on Knebel: Scouting grades: Fastball: 70 | Curveball: 65 | Changeup: 45 | Control: 50 | Overall: 50 Like Huston Street had done a decade earlier, Knebel went from an unheralded Texas prepster to an instant star as University of Texas closer to a supplemental first-round pick to a big leaguer less than a year after the Draft. Signed for $1,433,400 by the Tigers as the 39th overall choice in 2013, he became the second player from that draft -- behind only Kyle Crockett of the Indians -- when he made his debut on May 24. Two months later, Detroit traded him to the Rangers along with prospect Jake Thompson in exchange for Joakim Soria. Knebel definitely has the weapons and competitive makeup with which to close games. His fastball ranges from 91-98 mph with tailing action, and he uses his height to throw it on a downhill plane. When he stays on top of his curveball, it can be just as nasty as his heater, arriving in the low 80s with sharp downward break. There's some funkiness to Knebel's delivery, but it adds more deception than it detracts from his ability to throw strikes. He flashes a decent changeup, which had the Tigers initially considering trying him as a starter, but his future definitely is as a reliever. Scouting report for Diplan: Scouting grades: Fastball: 60 | Curveball: 50 | Changeup: 45 | Control: 50 | Overall: 45 Small right-handers usually don't command $1.3 million bonuses on the international market. But Diplan did exactly that last July as part of the Rangers' aggressive international push, because he combined stuff and polish like few 16-year-olds. The Dominican was the consensus top pitching prospect in the 2013 July 2 class. Diplan has a loose quick arm that can deliver fastballs as hot as 96 mph, and he usually pitches around 90-91 mph at this point. Though he's not big, he has room to add strength and should have a consistently above-average heater once he fills out. Diplan has a pair of promising secondary pitches, with his curveball showing more upside than his changeup. Though there's some effort in his delivery, he does a good job of throwing strikes. While he'll have to show he has the durability to remain a starter, he has the repertoire to succeed in that role.
