The right-hander will get the ball against the Giants on Thursday, his first start since May 11, when he allowed three runs in 4 2/3 innings. At that point, including that start, Dessens was 1-4 with a 7.56 ERA as a starter. He averaged less than five innings per start, which put additional pressure on an already taxed bullpen.
Dessens has had success in the relief role, compiling a 2.37 ERA. His performance out of the bullpen earned him another chance at the rotation.
"I'm looking forward to it," Dessens said. "I feel more comfortable as a starter and I feel I can help the team more as a starter."
Thursday's game is the opener of a four-game series against the Giants at SBC Park. This series will take the Diamondbacks up to the All-Star break.

Players to watch
The entire Diamondbacks offense. How will they respond after picking up just one hit against Kazuhisa Ishii on Wednesday night.
"A lot of our hitters didn't have an approach, didn't have a plan. [Ishii's] tough against lefties, so you give your lefties the benefit of the doubt, but our right-handed hitters have to put quality at-bats together. There's no excuse for that. We have to be accountable for our at-bats and we have to know how to play the game right. It's getting old. It's getting really old." -- Shea Hillenbrand, who had the lone hit Wednesday night against IshiiOn the Internet MLB.TV Gameday AudioGamedayOfficial game notesOn television:
