GOODYEAR, Ariz. -- For some veterans, Spring Training is a way to work on their game and ease into the routine of playing baseball again.

Conor Jackson, though, knew coming off a 2009 season lost to Valley Fever, it would be a different story for him this spring.

"I needed to come in and start off good and show everybody that I'm healthy and good to go and there were no question marks from [D-backs manager A.J. Hinch] or the front office," Jackson said. "I feel good, everything feels like it's jelling right now."

Jackson has certainly shown that so far. With a 3-for-3 performance Tuesday against the Reds, his is 6-for-12 with a pair of doubles and a home run.

That comes on the heels of a successful winter ball campaign in the Dominican Republic, which no doubt helped jumpstart him for spring.

Competition in the outfield figures to be fierce with Gerardo Parra, who hit .290 last year as a rookie, looking to push for playing time.

"As much as everybody can say that it's my spot, you've got a guy that I'm battling with who hit .290 last year," Jackson said. "Parra's a good player. It's definitely still a competition. I'm just doing my bit to show everybody that I'm ready to go."
