Its becoming a more popular term in baseballs vernacular: spin rate. On some broadcasts, its almost as ubiquitous as the velocity readings. What exactly are they referring to? What do we know about how its tracked and what the data means? Does it deserve the hallowed treatment its beginning to get? Lets start with the basics.What is spin rate?At the heart of the Statcast numbers were seeing now is the Trackman system. In 2015, all major league parks had set up the radar equipment from the Danish company, in addition to existing cameras that gave us SportVisions PITCHf/x data. Radar is superior to video tracking when it comes to a high-velocity spinning ball, particularly because it can directly measure some things (like spin rate) that were merely extrapolated from movement before.In order to get the best data, MLB Advanced Media is now combining a series of high-definition optical cameras in each park with the radar system. Theyre working to have the two systems hand off certain high- and low-trajectory batted balls so they get the best of both worlds.Now, instead of judging spin backward by movement, the radar system can tell us the spin of the pitched baseball in revolutions per minute. That spin changes the movement of the pitch, so in some ways, its a one-number way to sum up the movement on a pitch. But theres evidence that spin may have something to do with deception as well, because batters naturally try to read the spin on each pitch.How MLB teams are using the infoTheres evidence that teams have been taking this information very seriously in recent years. Theyve had Trackman numbers in some form much longer than theyve been available for public consumption, and theyve been acting on it. In fact, the Astros admitted to claiming Collin McHugh off waivers because his curveball had a very high spin rate, and Ryan Buchter recently talked to me about how much the Dodgers value spin rate, especially from their relievers. Even if we dont know everything about it, the teams themselves are telling us its important from their actions.Now lets look at how spin rate matters for the various pitches.Which fastballs have the most spin?Dre Mont Jones Youth Jersey . "I dont know that were close," said general manager Alex Anthopoulos. "I just think, right now, the acquisition cost just doesnt work for us right now. I dont know if I can quantify how far off or things like that that they might be but I would say we continue to have dialogue. Gary Zimmerman Womens Jersey .

Joe Flacco Broncos Jersey . -- Nate Robinson has played for seven teams, so beating one of them is no longer a rare occurrence. Peyton Manning Broncos Jersey . Numbers Game examines the deal that sees Michael Del Zotto and Kevin Klein switch places. The Predators Get: D Michael Del Zotto.Throughout the Stanley Cup Playoffs, NHL on TSN analyst and former NHL goaltender Jamie McLennan ranks the netminders after each game night. Today he grades the performances from Pittsburghs Tomas Vokoun and Craig Anderson and Robin Lehner of the Ottawa Senators. Number values assigned are out of five with five being the best performance. Tomas Vokoun - 3 – He did enough for the win, but was not overly sharp. Post play in his feet is the way to get to him (see: Turris goal). He was out of position and turned facing the wrong way on the Pageau goal, so two of the three goals against he would like back. The strength of his game tonight was the timely saves. Two big ones on Greenning and Conacher in the second period that were aggressive and unorthodox, but the saves allowed Pittsburgh to stay ahead and ultimately get the win.dddddddddddd Craig Anderson - 1 - The first two goals he would like back to Crosby: Through the body and a short side goal that he gets caught cheating on. Crosbys hat trick goal was on a screen by his own defence. Robin Lehner - 4 - Mop up duty for Lehner. He made big saves on Iginla, Kunitz and Crosby to keep the game close for the Sens. He was very poised and confident. He plays a big game, with not a lot of holes through the body, which allows him to explode into saves, like the big one on Malkin in the third period. ' ' '
