CLEARWATER, Fla. -- Phillies general manager Ruben Amaro Jr. declined comment Thursday when asked about a Baseball America report that the organization turned in two college players to the NCAA for rules violations.

Amaro said he could not comment because it is an investigation.

Philadelphia drafted Oregon State left-hander Ben Wetzler in the fifth round and Washington State outfielder Jason Monda in the sixth round of the 2013 First-Year Player Draft. Neither signed. Baseball America reported the Phils told the NCAA in November the players violated its "no agent" rule.

College players are not allowed to hire agents before they sign, but it is widely known and accepted they use advisors to help them negotiate before the signing deadline, otherwise it would be a college athlete negotiating on his own.

The NCAA has made Wetzler ineligible to play. It recently reinstated Monda.

Amaro directed questions to Phillies assistant general manager Marti Wolever, who declined comment to Baseball America.
