In the 2008 draft, the Diamondbacks select Daniel Schlereth, LHP, Arizona.
Here are a few chunks of scouting info on the man:
minorleaguebaseball.com
Fastball: Schlereth was throwing consistently at 93-94 mph.
Fastball movement: It's mostly straight, though sometimes there's a little tail.
Curve: He throws a power curve, 80-82 mph, sometimes up to 84. It's a downer with a little tilt, at times 12-to-6.
Changeup: He has a strong average, at times plus changeup which he throws 79-80 mph.
Control: He's still hit or miss with his command.
Poise: He's got a football mentality and enjoys the back-end relief role.
Physical Description: Schlereth is a compact, strong lefty, kind of like J.C. Romero.
Medical Update: He had Tommy John surgery his senior year of high school. Last year, he missed nearly a month with a rib/oblique injury. He's been healthy this year. Strengths: Three possible pitches to use; a jump in consistent velocity this year.
Weaknesses: Command. He'll rack up some strikeouts, but he's also going to walk some.
Summary: Schlereth was drafted in the eighth round last year by the A's, but chose to return to Arizona. He's got three decent offerings, though he struggles at times with commanding them. He misses a lot of bats, but he also will pile up walks at times. He's got a football mentality on the mound, courtesy of his father, former NFLer Mark, and could be the kind of left-handed setup man who gets to the bigs quickly.
Keith Law of ESPN says: "Schlereth is another college reliever who should be quick to the majors, even getting there this year. He has a plus fastball and breaking ball. He should wreck left-handed hitters in the big leagues. I had him ranked lower because he has a limited history. He blew out his elbow and had Tommy John surgery. He only came back to form over the last two months."
Baseball Prosectus had him going to the Red Sox with the 30th pick, saying "Schlereth would be the best college reliever still on the board, and his power stuff makes him possibly closer-worthy and anything but a one-sided specialist. The son of former NFL player and television analyst Mark Schlereth, he's built like a bulldog and brings a gridiron mentality to the mound. More importantly, his velocity was up to 97 mph, and his slider was a true wipeout offering.'' Baseball America's mock draft saw Schlereth going higher, at #23. In his mock for mlb.com, Jonathan Mayo nailed it, calling Arizona to pick him.
