Kaleb Holbrook was preparing for his second game as a catcher for a summer league in Connecticut on June 8 when his phone began to ring with calls and text messages of congratulations. “I just checked my phone before the game started, and my friend from school was calling congratulating me, telling me that I had been drafted by the Los Angeles Dodgers and I didn’t know what he was talking about,” said Holbrook, a 2011 Dawson County High School graduate. Selected in the 35th round, the 6-foot, 195-pound catcher was the 1,054th overall pick after attending the Dodgers’ pre-draft workout last month at Woodward Academy in College Park.
