PHOENIX -- With Justin Upton out of the lineup with a bruised left thumb, D-backs manager Kirk Gibson has been deciding on a game-by-game basis who should start in right field.
On Wednesday, Gibson played Jason Kubel in right and Gerardo Parra in left.
On Thursday, Gibson switched Kubel and Parra.
Parra, who won a Gold Glove Award last year, is regarded as the better defender of the two.
"[The Braves] have a lot of left-handed hitters in there today and [Josh] Collmenter is on the mound," Gibson said when asked what led to his decision to flip the outfielders. "I just thought I'd rather have Parra in right tonight -- they'll probably hit them all to left for all I know. It's just the thought process; if they hit the ball in a corner that way, Parra has a stronger arm to maybe cut down a triple."
Kubel said he doesn't really have a preference, but allowed that he was "a tad" more comfortable in left than he is in right.
