The torn labrum injury he incurred in 2004 required surgery and a year of physiotherapy. During that time he read Michael Lewis's book "Moneyball" and got an internship position with STATS, Inc. of Chicago. "I was one of their reporters, which meant that I looked at game video and plotted the 'TVL'–type, velocity, and location–of every pitch", Fuld said. "They have this grid where you click on exactly where the ball crosses the plate. Play the tape, pause, and repeat." He also began seeking out stats that were not already kept. "There's so many statistics out there that I thought 'There's no stats on foul balls,' so I picked a few players and started tracking them, thinking I'd find something", Fuld said. But his bag that contained the notebook with all his stats was stolen.
