Diamondbacks top prospect Jarrod Parker was chased in the fourth inning for the second straight start Sunday, surrendering seven runs on seven hits in Mobile's 14-10 loss to Mississippi.

Parker (0-2) gave up two homers, walked three and struck out one as his ERA climbed from 17.18 to 18.00.

Selected ninth overall in the 2007 Draft, he missed the second half of the 2009 season before undergoing Tommy John surgery that sidelined him for all of last year. In his season debut on Monday, the 22-year-old right-hander gave up eight runs -- seven earned -- over 3 2/3 innings, hitting two batters, walking three and giving up a grand slam.

Sunday's start wasn't much prettier.

Parker walked Cory Harrilchak to open the game, allowed a single to Willie Cabrera and served up a homer to Donell Linares. He issued another free pass to Ernesto Mejia, who scored on C.J. Retherford's double to make it 4-0.

After getting two quick outs in the second, Parker gave up another base hit to Cabrera but retired Linares to fly out to left field. He yielded two hits in the third before getting Gerardo Rodriguez to ground into an inning-ending double play.

Jordan Kreke drew a leadoff walk in the M-Braves' fourth and Harrilchak followed three pitches later with his first Double-A homer to end Parker's afternoon after 77 pitches.
