The Phillies on Friday signed their second and third picks from the 2013 First-Year Player Draft, Andrew Knapp and Cord Sandberg. Knapp, taken 53rd overall, is a 21-year-old catcher out of Cal-Berkeley. He produced a slash line of .350/.434/.544 with 16 doubles, eight homers and 41 RBIs (he led the team in all categories) as a junior this past season. The 6-foot-1, 190-pound Knapp bats from both sides of the plate and can hit for both average and power.
