Reynolds at third ... for now

Reynolds at third ... for now

DENVER -- Mark Reynolds is the D-backs third baseman.

At least for now that is.

The acquisition of outfielder Adam Dunn on Monday along with the projected return in a little more than a week of outfielder Justin Upton from an injury rehab assignment, has led to speculation that Arizona manager Bob Melvin could shuffle his defense dramatically in order to get everyone's bats in the lineup.

That would involve putting Dunn either in left or at first base with Conor Jackson possibly moving from left to first, Chad Tracy shifting from first to third and Mark Reynolds going from third to second.

Call it the nuclear option, a last resort.

"If they want me to I will," Reynolds said of playing second. "It won't affect anything. I feel comfortable over there, I feel comfortable at third base. Whatever they want."

Melvin does not seem to want that right now.

"I told him yesterday you're our third baseman, don't worry about second, just play third," Melvin said. "That's what I told him. Whether or not that stuck in there I don't know."

When asked if Reynolds, who played second base at times last year with Double-A Mobile, has taken grounders there this season Melvin said, "Maybe recreationally, not by design."

Any plans to have him do so?

"As of right now, no," Melvin said. "With our club anything is possible."
