Why is Justin Verlander's curveball so hard to hit? And why are even the most accurate radar guns fooling scouts and they don't even know it? The answers are provided by a Danish technology company that may change the way teams scout and evaluate pitchers. Trackman, a company established in 2003, is taking some old-school observational theory out of baseball and replacing it with hard data derived from 3D Doppler radar ball flight measurement. The company already has established a foothold in professional golf and is bringing its tracking technology to baseball, where More MLB Sportvision's Pitch-F/x system, another ball tracking Latest MLB News technology, has been used widely for years.

UConn's Walker entering NBA draft Trackman measures not just the speed of the pitch, but also the key variable: the distance between the Bonds jury deliberates 3rd day without a verdict pitcher's release point and the plate. With those measurements, Trackman defines not only the time Video component of a fastball -- "flight time," if you will -- but also defines in irrefutable data why scouts might describe a pitcher as "sneaky fast" or throwing a ball with "hop." Take, for instance, Robertson, the 5-foot-11 set-up reliever for the Yankees with that "lively" fastball. Robertson does not have exceptional size or velocity, but he ranks fourth among all active pitchers with at least 100 innings in strikeout rate (11.7 per nine innings, better than every pitcher except Carlos Marmol, What's the best NBA Suzuki homers in Jonathan Broxton and Francisco Rodriguez, all of whom are well-paid closers.) fit for Kemba Walker? 10th to lift A's over White Sox Why is Robertson so difficult to hit?

Peter King: NFL teams hung up on Clayborn's That's the kind of advantage he gains over the average pitcher by releasing his fastball with so much strength issues; mail extension. The radar gun (and Trackman) clocks Robertson's fastball at an average of 93 mph. But because SI Photos Robertson shortens the distance between his release point and home plate, his "effective velocity" is 95 mph. It looks like 93 but gets on a hitter like 95 -- thus the illusion of "hop." When it comes to "stealing" distance -- and distance equals time for a pitcher - here are the top 10 pitchers from one AL park last year, ranked by fastball extension in feet and inches: Pitcher, Team Extension MPH FT* Effective MPH Leading Off: Sports Figures Dave Robertson, Yankees 7-0 93 .403 95 Pictures of the With Their Own Week Statues Sergio Santos, White Sox 6-10 96 .386 98 Jared Weaver, Angels 6-10 91 .411 93 SI Vault Jeff Niemann, Rays 6-10 93 .401 95 Featured Stories Mark Hendrickson, Orioles 6-10 88 .422 90 WOLFF : Carmelo leads Syracuse to title (4.14.03) Jamey Wright, Mariners 6-9 91 .410 93 BLANDA : How I became a NFL star (7.19.71) Felix Hernandez, Mariners 6-8 94 .399 95 SMITH : Durocher, Mays have Giants rolling (8.16.54) David Purcey, Blue Jays 6-8 93 .404 94 Covers Gavin Floyd, White Sox 6-8 92 .407 93 Tommy Hunter, Rangers 6-7 91 .409 93 Average MLB 5-10 92 .416 92 * = Flight Time What about breaking balls? Trackman can measure the spin rate of all pitches in revolutions per minute. Pitchers such as Sandy Koufax and Pedro Martinez could throw wicked breaking balls because they had long fingers that could generate tremendous spin, though no could quite quantify it. Spin rate is important for breaking balls because it not only correlates to movement but also to deception. 04.04.11 04.11.11 The seams on a baseball are the decoder ring for a hitter. A fastball spins so fast the hitter does not see the seams, only a solid sphere. But a breaking ball, which does not travel as fast, can offer a clue of its intentions with its spinning seams. The faster a breaking ball spins, the harder it is to see the seams, so the more it looks like a fastball for a greater period of time. "I didn't pick up the spin," is the common lament of a fooled hitter who mistimed a breaking ball. Acccording to Trackman data from one AL park last year, here are the pitchers with the fastest average curveball spin rate: Verlander's curveball spins 23 percent faster than an average major league curveball, an astonishing difference. Moreover, you begin to understand the quality of Hunter's stuff when you notice he is the only pitcher to show up among the top 10 for fastball extension and curveball spin rate.

Again, here are Trackman's fastest average spin rates from one AL park last year: The data is fun and interesting, but it's only valuable because of how it is used, not just how it is compiled. For instance, once you measure fastball extension, just how important is that information? Trackman has that answer, too. It divided all pitchers with at least 100 innings into two categories: pitchers with below the 5-foot-10 average fastball extension and those with above average extension. Then it looked at ERA and strikeout rates. What it found was a correlation between greater extension and a lower ERA and higher strikeout rate: ERA and Strikeout Rate on Fastballs Fastball Extension ERA SO/9 IP Less than 5-10 4.18 6.6 Greater than 5-10 3.95 7.3 http://sportsillustrated.cnn.com/2011/writers/tom_verducci/04/12/fastballs.trackman/index. ... 4/12/2011 Trackman charts rpms, spin rate on pitchers like David Robertson - Tom Verducci - SI.co ..
