Caught in the Act Sportvision’s Fieldf/x system tracks every player on the field and logs their movements some 20 times per second. Last summer, the company invited a handful of analysts to dig into the data gathered so far from Giants’ games at AT&T Park in San Francisco. Jeremy Greenhouse, a 22-year-old Tufts University graduate (who has since been hired by Bloomberg Sports), presented color- coded illustrations of a fielder’s probability of making a catch every step along the way. Adaptations are presented here. Probability of making the catch: ● 0–20% ● 20%–40% ● 40%–60% ● 60%–80% ● 80+% ● Not calculated Good Catch, Great Timing Good Catch, Bad Route Rockies center fielder Carlos Gonzalez makes a running catch Gonzalez makes a catch on a pop fly off the bat of Juan Uribe on a ball hit to the wall by Bengie Molina Gonzalez made the By stepping backwards instead 50-50 play by timing of forward at the crack of the bat, his leap perfectly Gonzalez made an easy play hard but was able to recover from his mistake Shortstop Troy Tulowitzki moves to cut off the throw Left fielder Seth Smith backs up the play vs. Colorado Rockies, May 31 vs. Colorado Rockies, May 31 Carlos Gonzalez Carlos Gonzalez Hang time: 5.3 seconds Hang time: 4.4 seconds Distance to catch: 35.8 yards Distance to catch: 21.6 yards No Catch, Good Plays Great Catch, Great Dive Pablo Sandoval smashes a ball into the left-field gap that neither Orioles left fielder Corey Patterson makes a diving catch on a ball the Rockies Seth Smith nor Gonzalez are able to reach hit down the line by Nate Schierholtz When the ball is hit, Patterson has little chance, but his dive rescues the play Both Smith and Gonzalez gave them- selves a chance by getting a good jump on a near-impossible ball Sandoval rounds first and Right fielder Nick Markakis hardly moves heads for second vs. Colorado Rockies, June 2 vs. Baltimore Orioles, June 16 Carlos Gonzalez & Seth Smith Corey Patterson Hang time: 4.8 seconds Hang time: 3.1 seconds Distance to catch: 30.6/29.5 yards Distance to catch: 16.6 yards .
