It's reported that Arizona has selected Brett Lorin from the Pirates in today's Rule 5 draft. Lorin was a fifth-round pick by the Pirates in 2008, and spent last year in High-A, posting a 2.84 ERA over 25 games, 17 of them starts, and 117.1 innings of work, with an impressive 99:19 K:BB ratio. However, by the terms of the pick, the 24-year old right-hander has to remain on the 25-man roster all year, or be offered back to the Pirates.
The Diamondbacks did well with their last Rule 5 pick, Joe Paterson, in 2010, but he was considerably more advanced than Lorin, having been playing at Triple-A the season before. If Lorin can make the leap from High-A to the majors, it will be a significantly greater adjustment.
No Diamondbacks' prospects were chosen by any other teams in the draft.
