The Pirates have agreed to terms with Mexican righthander Luis Heredia for $2.6 million, according to a report from Baseball America correspondent Dejan Kovacevic.

Heredia, who at 16 is around 6-foot-5, 180 pounds, was seen by several scouts as the top amateur pitcher on the international market this summer. His best pitch is his fastball, which has sat at 88-91 mph and touched 92-93 according to recent reports. Subscribers can read BA's complete scouting report on Heredia, who had already signed his rights away to Veracruz of the Mexican League, which meant teams were negotiating directly with Veracruz to sign Heredia.

A $2.6 million deal would be a franchise record for an international amateur bonus and the largest bonus ever for a Mexican amateur. It would also be tied with Astros Dominican outfielder Ariel Ovando for the second-highest bonus of the summer, trailing only the $2.8 million the Blue Jays gave Venezuelan righthander Adonis Cardona. A $2.6 million signing bonus would also tie Heredia with Ovando for the No. 5 bonus of all-time for an international amateur prospect.
