Jays Prospect Watch: pitcher Fabio Castro

The Blue Jays could potentially have pulled off a heist in the deal that sent Matt Stairs to the Philadelphia Phillies last August. In that swap, Toronto acquired left handed pitcher Fabio Castro, and the results thus far have been very encouraging.

The clubs brass has decided to try the 24 year old prospect out as a starter with the New Hampshire Fisher Cats in Class-AA. In four starts, the former Phillie is 2-0, with an amazing ERA of just 0.83! The southpaw has allowed just 2 runs in 21.2 innings, while striking out 24 against 3 walks. Castro was named the Eastern League pitcher of the week on Sunday.

Despite his young age, Castro has some major league experience. In 2006, he appeared in 20 games between Texas and Philadelphia, and the following year, took part in 10 games, starting one with the Phillies.

At the time of the Jays acquired Castro, he was considered a mid-tier prospect. With his early success in 2009, Castro has served notice that he's a player worth keeping an eye on.
