The Blue Jays announced the signing of Mexican righthander Roberto Osuna, considered by many scouts to be one of the top 16-year-old international free agents on the market this summer.

Here is Baseball America's scouting report on Osuna from July 1:

"Osuna is the nephew of righthander Antonio Osuna, who pitched nearly 500 innings as a big league reliever from 1995-2005, mostly with the Dodgers. Roberto represented his country in Lagos de Moreno, Mexico at the 16-and-under COPABE Pan American championship last October, when he ran his fastball up to 93-94 mph. He pitched against Team USA in the final game on three days rest and allowed four runs and nine hits in six innings in an 11-4 loss, though he struck out seven and didn't issue a walk. He finished the tournament with a 3.79 ERA in 20 innings and a 20-2 K-BB mark. He then signed with Mexico City in the Mexican League, and was already pitching for the club in games, with a 5.49 ERA with 12 strikeouts and 11 walks in 20 innings, facing hitters who are 10-20 years older than he is.

Osuna has a quick arm, advanced feel for pitching and a fastball that ranges from 88-94 mph, and his velocity has been inconsistent. He has an advanced curveball for his age, though it can get slurvy, and he shows feel for a changeup. Due to his thick frame, he'll have to keep his conditioning in check. Any team that wants Osuna will have to purchase his rights from Mexico City, a transaction that typically results in the team keeping 75 percent of the signing bonus. Several teams figure to have interest in Osuna, but a frontrunner has not emerged."
