PHOENIX -- Jarrod Parker's stay in the California League was a short one.
The D-backs' top pitching prospect found out Monday that he had been promoted to Double-A Mobile, though, technically, the transaction will not be announced officially until just before his scheduled start Saturday.
Parker, the team's top pick (ninth overall) in the 2007 First-Year Player Draft, spent the 2008 season at Class A South Bend, where he was 12-5 with a 3.44 ERA in 24 starts. This year, the club started him out at the more advanced Class A league, and it certainly did not faze him.
In four starts this year, Parker was 1-0 with a 0.95 ERA. In 19 innings, the 20-year-old right-hander walked four and struck out 21.
"Parker was in control in each start and demonstrated the competitiveness, approach and pure stuff that warranted a promotion," D-backs farm director A.J. Hinch said. "He showed the ability to make adjustments and improved command of his secondary pitches. We had a plan to have him pitch at multiple levels this season, and his approach and performance this early in the season made it a comfortable decision."
