Rated Rookies: Week One by Bryan Smith April 10, 2013 One of the great subplots of every Major League season is the rookies that come up and show a glimpse of baseball’s future. It’s what had us enthralled by Jackie Bradley Jr. all spring, what has us dutifully analyzing Julio Teheran appearances, and what has us so eagerly waiting for Jurickson Profar and Wil Myers. This season, we will track rookies, both the prospects and suspects, as they make adjustments to playing in the bigs. This bi-weekly list will highlight rookies who have accomplished the most in 2013, regardless of future projection (though that will always be discussed). These are the players whose week one performances deserve recognition. 1. Dan Straily, RH SP, Athletics If we’ve learned anything from Yu Darvish this season, it’s that success pitching against the Astros is not exactly analogous to pitching against baseball’s other 29 teams. The Athletics know this, why is probably why just one day after an 11 strikeout, 0 walk performance (a start worth an unofficial 0.6 WAR by our metrics), the A’s were comfortable sending Straily back to Triple-A. As sixth starters go, Straily is an excellent one, with a fastball at 90-93 mph, 83-86 mph slider, and 82-85 mph change (let’s agree to ignore that low 70s curveball, please). He showed great command against the Astros, the best he’s had in all 8 starts at the Major League level. But, I don’t want to get too wrapped up in Straily’s success. The Astros, as we’re finding out, are a historically swing-and-miss team. All 11 of Straily’s strikeouts were of the swinging variety, and amazingly, nine were against left-handed hitters. Brett Wallace and Rick Ankiel struck out a combined 6 times, all on Straily fastballs. While Baseball America’s scouting report of him, as the A’s #6 prospect, reads “[His] slider and change up are his two best offerings and account for the bulk of his strikeouts,” that wasn’t true against Houston. Eight of the 11 strikeouts were from the fastball, and a remarkable number of them looked like this to Jason Castro — right down the heart of the plate. If you want to see why we simply can’t get too excited about Straily yet, consider the caliber of competition: 2. Jose Iglesias, SS, Red Sox The idea of Iglesias being a no-hit shortstop is overstated, as he’s just too good a contact hitter to deserve that title. So far, the shortstop is making contact on 96.3% of the balls he’s swung at in the zone, and even 71.4% on balls out of the zone (versus 2013 big league averages of 86.3% and 61.7%). And this year, he’s making sharper contact, particularly when he can hit the ball to the left side. When Iglesias has been able to pull the ball this season, good things have happened: three balls down the line, three singles pushing the shortstop too far to his right, one slow infield hit to third. Overall, 7-for-11. On the other hand, the balls where he hasn’t (stripping away the bunts): pop up to 1B, 1-6-3 double play, fly out to right. 0-for-3. This has been true for the entirety of his small sample size big league career: a solid .430 wOBA to left field, but just .121 to CF and .209 to RF. It will be interesting to see how teams pitch Iglesias in the coming weeks, as they surely will look to take his ability to pull the ball away from him. But even when better-thought-out pitching and simple BABIP regression take hold on Iglesias, we’ll still have his defense. My favorite play so far came on April 5, after he was hit by a Josh Johnson fastball right on the elbow, just one play before he came out of the game. He’s simply one of a half-dozen players alive that can range to his right, and with an injured elbow, still make a good throw to get Jose Reyes at second base. (The video is no longer able to be embedded, instead watch the highlight here.) 3. Hyun-Jin Ryu, LH SP, Los Angeles Dodgers Might the Dodgers mammoth payroll have a bargain, after all? Ryu has looked good, commanding his fastball, living on the outside corner, and showing a real good slider. The part of Ryu’s arsenal that I think needs to worked out of his system is the slow curveball. He’s thrown just 28 this season, so we’re dealing with a small sample size, but it grades out as mediocre as it performs statistically. Per Brooks Baseball, Ryu’s curveball — among his four pitches — has both the highest Ball% and the highest BIP%. It’s a bad offering, and given the solid grades his slider and change up would get, I don’t quite see its point. It does feel that with two starts of information, we can better forecast Ryu’s season. I agree with Dan’s ZiPS projection where home runs are concerned; I think Ryu will give up a lot. I don’t see a ton of movement in that fastball, so he’ll be living on the edge with every mistake. The strikeouts in that ZiPS forecast feel high — he’s tough against lefties, and will continue to be, but I must wonder if RHB’s will strike out at a high rate. His six strikeouts in the Pittsburgh game: two to pitcher Jeff Locke, one to back-up catcher Mike McKenry, two to Pedro Alvarez (a real victim to LHP), and one to Gaby Sanchez on a good change-up. It feels that Ryu will really struggle when opposing managers realize the necessity of stacking their lineup with right-handed hitters. We’ll see who adjusts quickest. 4. Jose Fernandez, RH SP, Miami Marlins For fear of our readership getting Fernandez overload, I’ll defer you to read Paul Swydan’s breakdown of Fernandez debut, and I’ll simply add 3 more GIFs to those already offered by Carson Cistulli and Eno Sarris. Here are the final three pitches from my favorite at-bat during the Fernandez outing, Ike Davis in the second inning. In three consecutive pitches, we see the whole arsenal, we see command, and we see plus-plus raw stuff. Fernandez is a good bet to frequent this space all year: Earning Consideration: T.J. McFarland, Jim Henderson, Evan Gattis, Rob Brantly, Jackie Bradley Jr, Matt Adams, Shelby Miller, Justin Wilson. Slumped out of the Rankings: Aaron Hicks, CF, Minnesota Twins The Twins have had a very deliberate, conservative path for Hicks since drafting him in the first round in 2008, allowing him to repeat Low-A, and never giving him an in-season promotion. But good Spring Trainings will occasionally force rash decisions, and in this instance, it does appear that a .370/.407/.644 line in 22 games in March was enough for the Twins to throw caution to the wind and make their #3 prospect a leadoff hitter. One of the reasons that Hicks finds himself atop the lineup, besides his plus speed, is a good batting eye. Hicks is patient, but this season, it’s been to a fault. In going through Hicks plate appearances, it’s clear that Hicks is too often leaving the bat on the shoulder when he shouldn’t. This season, per Baseball-Reference, the average Major League hitter sees 2.1 balls for every called strike against him. Hicks, by contrast, has seen 41 balls versus 27 called strikes, a ratio of just 1.52, or nearly 30% below league average. In 32 plate appearances, I have at least six instances in which Hicks watched a pitch go down the middle in the first or second pitch of an at-bat. Jack Moore recently wrote about Andrew McCutchen’s “controlled aggression”, Jack’s term for McCutchen’s increased ability to recognize and swing at easy strikes. This is a clear area that Hicks could use improvement, as he can’t let his ability to work the count interfere with the best opportunities he’ll have at a hit. The other area where I’d like to see improvement from Hicks is his ability to hit the change up. As a switch-hitter, Hicks is going to see a lot of change ups, and he’ll have to show better proficiency with the pitch. By my count, he’s seen 19 this year: 7 for balls, 2 for called strikes, 6 swinging strikes, 3 for outs, and one he reached base on a Chris Davis error. That is not good, and in fact, those 6 swinging strikes make up 37.5% of his swinging strikes for the season, despite seeing change ups in only 15.2% of all pitches. These issues seem more likely to be fixed developmentally than by adjusting on the fly; the Twins would be best served, in the short- and long-term, to let Hicks work on them in AAA. Statistics for this piece were thru April 8. I’d like to thank Carson Cistulli for his help with this post. I’d also like to thank Sebastian Pruiti, whose work on Grantland I miss very much, for inspiration for this series. It’s a delight to be back at FanGraphs. You can find me @bsmithwtny.
