The Pirates will not renew the contract of Rene Gayo, the director of Latin American scouting who was responsible for finding Starling Marte and Gregory Polanco, because of an investigation into financial impropriety.

According to The Athletic’s Ken Rosenthal, who first reported the story, the financial issue related to a kickback from a Mexican Summer League team.

Reached by the Pittsburgh Post-Gazette, Gayo declined to comment.

“We had been apprised of Major League Baseball’s investigation into alleged Rules violations committed by Rene during his tenure with the Pirates and the fact that MLB intends to discipline Rene as a result of those violations,” general manager Neal Huntington said in a statement. “Other than confirming our profound disappointment in the breach of trust that was the subject of MLB’s investigation, we will have no further comment on the investigation or MLB’s intended discipline.”

Gayo signed Polanco out of the Dominican Republic in 2009. He gave him a $150,000 bonus if Polanco would hit rather than pitch. Gayo signed Marte for $85,000 in 2007 and is also responsible for signing Edgar Santana, Elias Diaz and Jose Osuna.
