If D-backs left-hander Wade Miley can secure a win in Sunday's series finale against the Giants in San Francisco, he'll join some illustrious company.
Getting that win would make him only the second Arizona left-hander to reach 10 wins in back-to-back season, joining Randy Johnson, who did it from 1999-2002.
While Miley went 3-0 with a 2.00 ERA in five starts from July 25-Aug. 18, he's winless in his last three starts, going 0-2 with a 6.14 ERA. Against the Blue Jays in his last outing, Miley allowed five runs on eight hits in just 1 2/3 innings to mark the shortest outing of his career and his 10th loss of the season.
"I think he got mad and started overthrowing a little bit, and the ball was up," D-backs manager Kirk Gibson said after the start. "He kind of lost his composure. They're a free-swinging team, and they're swinging the bats well, and you can't get behind them, and you can't make mistakes."
Meanwhile, Madison Bumgarner gets the nod for the Giants as he looks for his first win since Aug. 2. While Bumgarner has put up solid numbers during that span, the Giants haven't been able to plate many runs.
Even though he's posted a 2.77 ERA over his last nine starts, the Giants have won just one of those games because they've combined to give Bumgarner just 20 total runs of support.
Bumgarner took a no-decision on Tuesday against the Padres, logging six innings and allowing two runs on five hits in a 3-2 loss.
"Hitting's hard," Bumgarner said after the start. "Everybody's working hard. We're having a tough time this year -- not just hitting. We're having a tough time pitching at times, defense. It's been a tough year all around."
D-backs: Prado a late scratch
Martin Prado, originally scheduled to bat fifth and start in left field on Saturday against the Giants, was a late scratch from the D-backs' lineup due to an illness.
The team announced the decision a little less than an hour before first pitch.
Adam Eaton moved from center field to take his place defensively, as well as going from batting leadoff to batting second. A.J. Pollock was inserted to the lineup, batting first and playing center. Second baseman Aaron Hill moved from second in the lineup to fifth.
Prado is hitting .350 in his last 33 games and has a .346 average since the All-Star break.
Giants: Posey takes BP
With a broken right ring finger that is steadily improving, catcher Buster Posey took regular batting practice on Saturday.
While Posey wasn't swinging hard, he was able to line a few balls into the outfield that would have been base hits.
Increasing his baseball-related activities each day, Posey could return to the Giants lineup in a few days.
Posey, who has missed four consecutive games since sustaining his injury Tuesday, also hit off a tee and played catch.
• D-backs utility man Willie Bloomquist is hitting at a .542 clip with four multihit games since returning from the disabled list.
• San Francisco has won 11 of its first 18 games against the D-backs this season, going 4-5 at AT&T Park and 7-2 at Chase Field.
