Major League Baseball is in the midst of a gambling probe.

From ESPN:

A former Washington Nationals part-time scout is at the center of a probe by Major League Baseball that has led to the firing of one scout and could result in disciplinary action against at least seven others, ESPN.com has learned.

Frank Falzarano, 54, of Seaford, Long Island, pleaded guilty in April to felony enterprise corruption and gambling charges and is to appear Sept. 24 in Queens County, N.Y., Supreme Court. Falzarano, who is free on $200,000 bail, faces a maximum sentence of 25 years in prison.

Sources close to the bookmaking probe identified one of the alleged bettors as Alan Marr, a respected high-ranking scout fired by the Baltimore Orioles last month. Marr acknowledged knowing Falzarano, but declined further comment when reached by ESPN.com at his home in Sarasota, Fla.

The investigation has identified “seven or eight” other scouts who bet through Falzarano, though it’s possible that number could grow as New York City police continue to pursue the case. Major League Baseball’s newly formed investigative unit is assisting law enforcement.
