贴一点scouting report Jarrod Parker RHP BA Signed for $2.1 million as the ninth overall pick in the 2007 draft, Parker ranked No. 1 on the Diamondbacks prospect list for three years. He made a strong comeback after missing 2010 following Tommy John surgery, especially in the second half when he regained his command and added an effective two-seam fastball. He made his major league debut in late September and earned a spot on the postseason roster. Parker has streamlined mechanics that allow him to get excellent velocity out of a smaller frame. He usually works in the mid-90s and has reached 100 mph with his four-seam fastball, and he operates in the low 90s with good sink on his two-seamer. He gets swings and misses with a slider and a changeup that he throws in the 81-86 mph range. His slider rated as a well above-average offering before he got hurt, though it's more of a plus pitch now. Parker also mixes in an average curveball. His easy delivery returned after his elbow reconstruction and scouts noticed a more mature pitcher on the mound. BP (101112) Five-Star Prospects 1. Jarrod Parker, RHP Year in Review: This top prospect missed the entire regular season while recovering from Tommy John surgery. The Good: Parker has impact-level stuff. His fastball sits in the low-to-mid 90s, touches 98 mph, and he's already re-found most of his velocity in the instructional league. His hard slider features excellent two-plane break and gives him a second major-league quality out pitch. He made great strides with his changeup in 2009, and most projected it as a big-league average pitch prior to surgery. He earned praises for his work ethic both prior to and following his injury, and he shows maturity beyond his years on the mound. The Bad: Parker throws strikes, but at times too many, as he'll often groove pitches down the middle instead of working both sides of the plate. He can lose touch and feel on his secondary offerings. Because of the missed year, he still needs to prove he was the player scouts saw in 2009. Ephemera: The ninth overall pick in the draft has produced just three 100-game winners in Ron Darling (1981), Kevin Appier (1987), and Barry Zito (1999). Perfect World Projection: Parker's stuff still gives him an All-Star ceiling. Fantasy Impact: He's an early selection among starters who delivers wins, ERA, and strikeouts. Path to the Big Leagues: While there's been some talk of Parker getting a serious look to make the major-league club next year in the spring, he'll be better served by coming back in a less pressure-filled environment, likely beginning the season at Double-A Mobile. John Sickels 2) Jarrod Parker, RHP, Grade A-:I wish his strikeout rate was higher and I think he needs some Triple-A time. I don't think he uses his breaking stuff as much as he did pre-injury, but overall he still looks like a future rotation anchor to me. The risk may be higher than some anticipate, but the ceiling is quite high. Jarrod Parker, RHP: Parker is a 23-year-old right-hander drafted in the first round in 2007 from high school in Ossian, Indiana. He missed 2010 recovering from Tommy John surgery, but he came back healthy and effective in 2011, going 11-8, 3.79 with a 112/55 K/BB ratio in 131 at-bats for Double-A Mobile, allowing 112 hits. Parker is the big prize in this trade, thanks to a 92-96 MPH fastball. He worked hard on developing his changeup this year, using it more often than his slider at times, and it's a solid offering. The slider was nasty before the surgery and while it has lost some bite, it is still very good. He also has a reasonable curveball that could use more development. Parker's combination of four pitches is overpowering when he's on, and while his secondary pitches still need a bit of refinement, most scouts think he'll develop into a rotation anchor as an ideal number two starter. Although his command still wobbles at times, his recovery from surgery was impressive and I am giving him a Grade A- in the 2012 Baseball Prospect Book. With the injury receding rapidly in the rearview mirror, Parker could be even better in '12. Collin Cowgill, OF R/L BA Cowgill put together the best season of his four-year pro career in 2011, earning Pacific Coast League all-star recognition and a late July callup to Arizona. He filled the fourth-outfielder role for the National League West champs and earned a spot on the roster for the postseason, where he delivered a two-run single in his lone at-bat. Cowgill is the prototypical grinder, the kind of player every manager wants on his team. He has a big bat wrap in his approach that leaves him vulnerable to quality fastballs, and his sweepy upper-body swing leads to struggles with breaking balls too. Yet he makes consistent contact, providing line drives to go with some gap power and a fair amount of walks. Cowgill is an above-average runner who can steal bases, succeeding on 34 of his 39 attempts last year. He's a solid-to-plus defender at all three outfield positions and has the strongest and most accurate outfield arm in the system. He's sometimes compared to Cody Ross for his gamer mentality and bats right/throws left profile. Cowgill may never be a big league regular but can carve out a career as a useful fourth outfielder. John Sickels 14) Collin Cowgill, OF, Grade C+: Like Pollock and Eaton, he has a broad range of skills. I think Eaton has a bit more zoomph in his bat so I rank him a notch higher with the grade. Collin Cowgill, OF: Another product of Arizona's 2008 draft, Cowgill was a fifth round pick from the University of Kentucky. Age 25, he is undersized at 5-9, 185. He hits right-handed but throws left, a combination which usually annoys scouts. Cowgill certainly annoyed pitchers in Triple-A in '11, hitting .354/.430/.554 with 13 homers, 51 walks, and 30 steals for Reno. The park/league environment helped him, and he was much less effective in the majors, hitting .239/.300/ .304 with 28 strikeouts in 92 at-bats for the Diamondbacks. At his best, he works counts well, draws walks, steals bases, produces moderate power, and is a very good defensive outfielder with a strong throwing arm. He's athletic and has better tools than most players his size, but scouts wonder if his swing will work against major league pitching. However, Cowgill has shown the ability to make adjustments before, and he has a good chance to have a long career as a fourth outfielder. Ryan Cook RHP BA Cook never posted a sub-5.00 ERA in three seasons at Southern California, but he showed enough promise for the Diamondbacks to ante up an $80,000 bonus after they took him in the 27th round of the 2008 draft. He had middling success as a starter in the lower minors before shifting to the bullpen and zooming from Double-A to the majors last season. As is the case with most pitchers, Cook showed better stuff in shorter stints, though no one expected it to jump as much as it did. He worked with an 89-93 mph fastball as a starter and suddenly had a consistent 95-97 mph heater as a reliever, topping out at 101. His fastball has riding four-seam life. Cook can miss bats with a hard splitter that he throws at 88-91 mph. He also has an 85-88 mph slider with more lateral movement than depth. He can throw the slider for strikes but doesn't always locate it well within the strike zone. Improved command is Cook's biggest need, and he got into trouble during his time in Arizona because he fell behind in the count too often. His eventual ceiling is as a set-up man. John Sickels 23) Ryan Cook, RHP, Grade C+: Another live-armed reliever who can be useful if his command holds up. Ryan Cook, RHP: A 24-year-old right-hander, Cook was drafted by Arizona in the 27th round in 2008, from the University of Southern California. He was very effective in the minors this year, posting a 2.21 ERA with a 62/22 K/BB in 61 innings, with 41 hits allowed, between Double-A Mobile and Triple-A Reno, collecting 19 saves. He received a major league trial but got hammered, giving up 11 hits, eight walks, and six runs in 7.2 innings. Cook throws quite hard in the bullpen, hitting 94-97 MPH and touching 100 at times. He offers a slider and splitter, but his command wasn't good enough in the majors, granted the sample size was small. If he throws strikes, his stuff would fit well in middle relief and it isn't impossible for him to pick up some saves eventually, if the command truly comes around. --
