Brandon McCarthy's Monday start was in question until D-backs manager Kirk Gibson confirmed Friday that McCarthy would start the three-game series opener against the Padres at Chase Field.
McCarthy, who is 2-8 with a 5.44 ERA this season, has struggled mightily of late with an 0-5 record and 8.59 ERA in his last five starts. McCarthy coughed up seven runs in 2 1/3 innings against the Reds his last time out. He is, however, 1-1 with a 1.23 ERA in his last three starts at Chase Field.
"I really felt like I didn't have anything, and then command-wise, it just wasn't there either," said McCarthy after his Wednesday start. "That's a pretty rough combo that I've got to be able to work through and at least get deeper and make something out of it and not let it turn into a complete train wreck."
On the season, McCarthy holds a 6.47 ERA in eight road outings, compared to a 4.53 mark in seven home starts.
Padres right-hander Tyson Ross is also coming off a subpar start after grinding through 6 1/3 innings, allowing five runs (four earned) on six hits in an 8-1 loss to the Pirates on Tuesday.
"If anything, I try and stay down in the zone more," Ross said of pitching in Arizona. "That's always a key when you're pitching -- being down. When you're in those hitter's ballparks, you really try and stay as low as possible. You need to limit hitters getting something elevated to hit."
The Padres are hoping Ross can get deep into the game after using six relievers in Sunday's 15-inning win over the Cubs.
Ross, who moved from the bullpen to the rotation in mid-July, brings a 3-6 record and 2.85 ERA into the start.
Padres: Venable rolling into matchup
Will Venable enters Monday hitting .368 with eight home runs and 14 RBIs in 33 games since the All-Star break.
Venable hit just .224 before the break, but he did have 11 homers and 32 RBIs in the first half.
The 30-year-old left-handed hitter had back-to-back three-hit games on Friday and Saturday against the Cubs, and he ended that three-game series with a 1-for-6 effort in Sunday's marathon.

D-backs: Hill, Prado get rest amidst hot streaks
Aaron Hill and Martin Prado each brought hot hitting streaks into Sunday, but D-backs manager Kirk Gibson elected to give them the day off in the finale against the Phillies.
Hill had hit safely in 16 of his previous 17 games (.391, 27-for-69), and since July 25, he had hit .378 (38-for-101) with five home runs, 10 doubles and 19 RBIs.
Prado is hitting .366 (37-for-101) in his last 20 games and .357 (50-for-140) since the All-Star break.
• Padres reliever Huston Street enters Monday with 17 1/3 consecutive scoreless innings.
• The Padres upped their record in extra innings to 7-5 with Sunday's 3-2 win over the Cubs.
