The Yankees have signed two more draft picks according to Robert Pimpsner of Baseball Digest, 8th round draft pick 1B Kyle Roller and 24th round draft pick RHP Conor Mullee. Both are expected to play with the Staten Island Yankees when they open up their season next week.
This means that the Yankees have now signed four of their 50 draft picks. The other two are 25th round pick 2B Casey Stevenson and 31st round pick RHP Mike Gipson. My guess is that they will all play for the Staten Island Yankees, as most college students who come out of the draft do, but you never really know until they announce the rosters.
