Worth noting

• With the return of Cody Ross, the D-backs have four outfielders -- Ross, Gerardo Parra, A.J. Pollock and Mark Trumbo -- for three spots.

Friday, D-backs manager Kirk Gibson gave Trumbo his first day off of the season and played Ross in left. Saturday, it was Pollock getting the day off, with Ross in right and Parra shifting to center.

"I'm going to rotate those guys," Gibson said. "They'll have to pull for each other."

• Trumbo entered Saturday's game in an 0-for-12 stretch, and Gibson hit him seventh for the first time this season rather than his usual sixth. Trumbo singled in his first at-bat and finished 2-for-4 with a run scored.

• Shortstop Didi Gregorius hit a three-run walk-off homer for Triple-A Reno on Friday night.

Gregorius, who lost out in the starting shortstop battle with Chris Owings this spring, had five RBIs in the game.
