Snake bites

• Miguel Montero hitting in the eight-hole didn't last long. The D-backs catcher was moved back up in the lineup Saturday, batting fifth.

Struggling at the plate this season, Montero was penciled in eighth on Friday for the first time since May 12, 2011. He ended up smacking a game-winning solo homer off the right-field foul pole Friday, lifting his batting average to .202.

"To be honest, I didn't even know his stats were struggling," first baseman Paul Goldschmidt said. "Because he does so many other things for us."

• Using a heavy shift against Ryan Howard this series, the D-backs kept the Phillies slugger hitless in eight at-bats through the first two games. Like many teams when they play Philadelphia, Arizona has nearly emptied out the left side of the infield to play all four infielders up the middle and to the right, Howard's pull side.

With no third baseman down the left-field line, laying down a bunt to the emptied area seems attractive at first glance, but D-backs manager Kirk Gibson thinks it's easier said than done.

"If you're Howard and you're down by a run, go ahead and bunt, but he isn't getting paid to bunt the ball, he's getting paid to hit the ball out of the park," Gibson said. "You make your choices, if he wants to bunt, go ahead and bunt. Like last night with Ian [Kennedy] on the mound, he's an exceptional fielder, so he would've had to make a good bunt. Not just any bunt is going to get you a hit. It's not that easy."

• With Triple-A Reno pitchers hitting for themselves next week, the D-backs sent Adam Eaton (elbow) to Class A Advanced Visalia on Saturday to resume his rehab assignment as a designated hitter.
