• Outfielder A.J. Pollock has been on quite a roll, hitting .409 over his past six games with a 1.207 on-base plus slugging mark.
"Just maturing," Gibson said. "Starting to trust things that he's seeing and learning what's been talked about. He's got a really good stroke, and ball jumps off his bat. He's got good wheels, he plays good outfield, he's a darn good player."
• Outfielder Alfredo Marte has hit .333 (4-for-12) since being promoted recently from Triple-A Reno.
"He swings the bat good, he's aggressive," Gibson said. "He's improved his defense in the outfield as well. He's a capable hitter off the bench. He fits in nicely."
• Injured pitcher David Hernandez celebrated his 29th birthday Monday, while former D-backs catcher and current Minor League manager Robby Hammock turned 37.
