From now until the end of the season, we'll be giving you an updated report on prospects who appeared on Keith Law's preseason top 100 or midseason top 50 prospect rankings. Today we're taking a second look at a trio of pitching prospects: Julio Teheran from the Atlanta Braves, Zach Lee from the Los Angeles Dodgers and Ty Hensley of the New York Yankees.

Julio Teheran
Position: RHP
Level: Triple-A (Gwinnett)
Age: 21
Law's preseason ranking: 18 | Law's midseason ranking: 19

Teheran has been a notable prospect since July 2, 2007, when he signed for $850,000 as a 16-year-old from Colombia, earning one of the biggest bonuses in his class. He shot through the minors, was considered one of the top prospects in the game and was knocking on the door of the big leagues with frontline starter upside. Teheran was forced to Triple-A due to the Braves' early season pitching depth and has struggled enough there (5.05 ERA) that when there was a rash of pitching injuries, Atlanta was forced to trade for Paul Maholm at the deadline.
