CINCINNATI -- Two nearly flawless starts dug the Pittsburgh Pirates out of their deepest slump.
The Pirates arrived in town with a six-game losing streak and came away with their first series sweep in Cincinnati since 2003. They did it with pitching -- Charlie Morton threw a five-hitter for a 5-0 win in the opener. McDonald (3-3) allowed one run and seven hits in 6 2/3 innings, handling one of the NL's most prolific lineups in one of its most hitter-friendly ballparks.
"This is a good hitting team with a lot of great hitters in their lineup," McDonald said. "For us to come in here and hold them to that many runs is a big accomplishment."
The sweep left Pittsburgh 13-12 on the road, a vast improvement over last year's 17-64 mark away from home. The Pirates didn't get their 13th road win last season until July 28.
Pittsburgh has given the defending NL Central champions a tough time so far this season, winning five of their past six games. Last year, the Reds took the season series 10-6.
"They've been playing us tough all year," manager Dusty Baker said. "It just goes to show you, anyone can beat you no matter where they are in the standings. We made a few mistakes, which didn't help, but it was mostly McDonald's pitching."
The Pirates' starters gave up one run and 12 hits in 15 2/3 innings during the series. Jay Bruce led off the second with a homer off McDonald, a drive to center that made an impact.
"The first inning was kind of slow," McDonald said. "I think that Bruce homer kind of woke me up a little bit, got a little fight in me. That's when I turned it on. I need to work on having that from the first inning on."
Cueto has done some of his best pitching against the Pirates, going 7-0 in his previous nine starts against them with a 1.74 ERA. But the right-hander had a rough time from the start of this one.
He walked two in the second inning, when the Pirates loaded the bases with one out. Ronny Cedeno took a called third strike on a full-count breaking ball that was right down the middle, and McDonald flied out to end the threat. Through two innings, Cueto threw 44 pitches -- 20 of them out of the strike zone.
Cueto got into trouble again after retiring the first two batters to open the fifth. Andrew McCutchen doubled and came around on Xavier Paul's single. After a walk to Garrett Jones, Walker doubled off the wall in center for a 3-1 lead.
It was a pleasing rally for the Pirates, who had struggled to hit with runners in scoring position lately.
"Incrementally, we've gotten better," manager Clint Hurdle said. "We've made some progress in some areas. It's good to see.
"I do believe it's closer to them getting in an offensive consistency that we should be in. I'll be looking forward to the day when this thing gets rolling, and it seems to me like it's getting closer every day we play," he said.
