The Padres announced that they have signed catcher Austin Hedges. They selected the 18-year-old in the second round of the draft after Baseball America named him the 12th-best position player prospect available and praised his defense. Tom Krasovic of Inside the Padres, who first reported the deal, says the agreement is worth $3MM (Twitter link).
