ST. LOUIS -- John Mayberry's two-run double in the sixth inning against St. Louis on Saturday night was just what he needed to get back on the right track.

"That was big," Mayberry said after the Phillies' 4-0 win, their third in as many days against the Cardinals. "To be able to come through in a big spot is always pretty gratifying."

The Phillies had loaded the bases against St. Louis starter Jaime Garcia by way of a double and two walks. Philadelphia starter Kyle Kendrick was clinging to a 1-0 lead, and Mayberry had the chance to break the game open. He ripped a low line drive past a diving David Freese at third base and put his team up, 3-0.

"I think it was a slider," Mayberry said. "I was just really trying to get one run in, and luckily was able to sneak one down the line."

Mayberry entered Saturday's game on a 4-for-23 skid in his previous nine games to drop his average to .232. At the beginning of that short drought, the Phillies' utility man had his average up to .247 -- the highest it had been in all of May.

The road is where the wins have been for Phils

ST. LOUIS -- Hunter Pence doesn't know why, but for some reason his team has been playing its best baseball lately while away from Citizens Bank Park.

The Phillies are 10-3 in their last 13 road games entering Sunday, with a .293 team batting average and an average of 6.5 runs per game. They're also slugging .445 as a team with 14 homers in that span.

"I don't really know. You just play the games," Pence said when asked what it takes to play that well on the road for so long. "When you're a good team you find a way to win. It's just been one of those things where it's early in the season and we've had some good games on the road, and some tougher series at home."

Prior to the 13-game stretch, the Phillies had gone 4-7 in their previous 11 road games with a .220 team batting average while scoring 2.4 runs per game. Last season, the Phillies set a club record and led the league with a 50-31 road record. Philadelphia has posted a Major League-best 327-261 record on the road since Charlie Manuel became manager in 2005.

The Phils are in the midst of a seven-game road trip, their second longest stretch away from home thus far this season. And while everything seems to be clicking during its current four-game winning streak, the team doesn't want to get too far ahead of itself.

"It's just a daily process," Pence said. "You don't really dwell on too much other than focusing on today. We've got good pitching and guys are swinging the bats. And it's just about timely hitting and good defense; with the pitching that we've got, it gives us a good chance to win every day."

Kendrick's shutout provides some rest for 'pen

ST. LOUIS -- Phillies manager Charlie Manuel said it was good for his bullpen to get some rest during Kyle Kendrick's first career shutout against the Cardinals on Saturday night. Catcher Brian Schneider said it, too. And yes, the Philadelphia relievers were also happy to have the night off.

"Anytime we can get a night off down there and get everybody to get a little rest in for their arms ... we've been throwing quite a few innings," right-hander Chad Qualls said. "It was definitely nice to watch [Kendrick] go out there and take all nine. Any rest is well rest for us."

Qualls has made 10 appearances in May entering Sunday, including going a season-long 1 2/3 innings against the Cardinals on Thursday. He also said it was important for closer Jonathan Papelbon, who leads the National League with 14 saves, to finish the night in the bullpen.

While both Qualls and rookie reliever Jake Diekman, who's made six appearances since getting called up from Triple-A on May 9, said they feel good physically, Qualls recognizes the need to give their bodies some time off.

"We're only about 50 games into it, so we still have over 100 games left. It's just kind of pace yourself, go about your business and try to stay consistent all year," Qualls said.

Worth noting

• Phillies pinch-hitters have 10 hits in their last 25 at-bats entering Sunday. They've hit two homers and have eight RBIs during that span. Before that, the Phils were just 5-for-42 while pinch-hitting.

• The Phillies are 20-10 this season when they score first, and 5-13 when their opponents score first entering Sunday. They've gotten on the board first in each of the first three games this series in St. Louis.

• Hector Luna made his fourth start of the season at first base on Sunday. He's 6-for-16 with a homer and six RBIs this season.
