KANSAS CITY, Mo. -- The Baltimore Orioles hit five home runs and snapped a six-game losing streak with an 8-5 victory over the Kansas City Royals on Wednesday night.

The five homers were the most for the Orioles since they bashed eight in a 19-3 win over the Philadelphia Phillies on June 16.

The six-game skid was Baltimore's longest of the season.

"There's another challenge around the corner tomorrow," Orioles manager Buck Showalter cautioned. "There's so much negativity around when things are going poorly and there's so much over-positiveness when things are going well, so you try to stay in reality. But the reality of how many games are left and where we're trying to get it does put a positive spin on that this time of year."

Orioles right-hander Wei-Yin Chen (8-6) posted his fourth straight win. He has not lost since dropping a 3-2 decision to the Yankees on July 21 in New York. Chen allowed three runs, 10 hits and one walk with four strikeouts in 6 2/3 innings.

"I think my breaking ball was working good enough today so I was able to mess up the hitters' timing," Chen said through interpreter Louis Chow. "I think we're all happy about (ending the losing streak). For me I didn't really think about the losing streak. Every day when we get to the ballpark all we think about is today's game."

"He was good tonight," said Royals manager Ned Yost. "He was really, really good. 95 MPH fastball, good changeup, good slider. Really worked the outside part of the plate well."

The Orioles connected for two-run homers in the third, fourth and fifth to build a 6-2 lead.

After the Royals got two second-inning runs, the Orioles answered quickly. Flaherty singled to lead off the third and third baseman Manny Machado hit the next pitch for a two-run homer to center, tying the score.

In the next inning, second baseman Jonathan Schoop's towering, two-out blast to left scored Pearce, who singled with one out. Schoop's deep fly to the back of the bleachers, measured at 427 feet, gave the Orioles a 4-2 advantage.

"I'm just trying to get good at-bats," Schoop said. "Get good pitches to hit and drive the ball, get some good pitches to hit and trying to get on base and do damage."

"I think it's a little reminder of what we lost for a long period of time," Showalter said. "Jon, early in the season, was looking like he was getting ready to do that and he hasn't had 200 at-bats yet. Jon's a strong young man. But he approaches it the right way. He's a guy that is capable of being as good as he can be. That's a comfort not only to me but to the fans of the Orioles."

In the fifth, first baseman Chris Davis delivered a one-out shot to center, scoring right fielder Gerardo Parra, who had singled.

"It's a tribute to him," Showalter said. "He's battled some real blisters with all the BP he's taken trying to get it going again. He didn't even take BP today because of that. It's a reminder of how hard these guys are grinding."

Kansas City rallied for a run in the sixth when designated hitter Kendrys Morales got the third of three singles in the inning to score left fielder Ben Zobrist.

Baltimore got the run back in the eighth on left fielder Steve Pearce's eighth home run of the season.

"Yeah, it's definitely been a while," Pearce said. "It feels good to contribute and a lot of people did tonight with home runs. It was just good to break out the way we did. It feels great and we'll build off of it. The other team kept trying to come back and we responded. We can't let up against this team or the good teams, whatever the lead is, we have to keep our foot on the gas pedal."

In the bottom of the inning, Royals third baseman Mike Moustakas hit his 15th homer of the season, a two-out, two-run drive into the right field bleachers, cutting the deficit to 7-5.

The Orioles answered with their final homer, a 416-foot shot to center to lead off the ninth by Ryan Flaherty, his fifth homer of the year.

"Ryan gave us a real lift tonight," Showalter said. "We needed that tack-on run. You're facing the best team in the American League last year and they've added players to improve on that, so it's a challenge. We've got a chance to split against the American League champions tomorrow and then we're moving on to Texas."

Left-hander Zach Britton closed out the Royals with a scoreless ninth, collecting his 30th save in 33 chances.

After Morales and catcher Salvador Perez each doubled in the second to produce the Royals' first run, right fielder Paulo Orlando and second baseman Omar Infante each reached on infield hits to score Perez.

Right-hander Johnny Cueto (9-9) went five innings, allowing six runs on eight hits and a walk, striking out eight. Cueto has lost consecutive starts for the first time since April 11 and 17, his second and third starts of the year.

"(He had a) really good two-seamer, heavy sinker," Yost said. "All three balls they hit homers on, they did damage on, were just spinning cutters. Maybe he's just flying off, not getting that bite on that cutter, but all three of them were just kind of spinning cutters."
