The St. Louis Cardinals have signed supplemental first-round pick Stephen Piscotty, according to Jim Callis of Baseball America. Piscotty signed for Major League Baseball's recommended slot signing bonus for the 36th overall draft pick, which is valued at $1.43 million.

Callis evaluated the Stanford product as "one of the best college bats available in the 2012 draft," citing his 2011 Cape Cod League batting title. ESPN's Keith Law meanwhile

Piscotty will head to Iowa and join the Cardinals' Class A affiliate. While he's listed as both an outfielder and third baseman, he will start off by playing third base for the team.

According to our signings tracker, the Cardinals have now signed four of their five first-round draft picks (including supplemental selections) with FSU's James Ramsey being the only one that remains unsigned. Don't expect anything to change on that front either, at least not until FSU is eliminated from the College World Series.
