Harrison Bader remained red-hot with a three-run homer and three hits while fellow outfielders Ryan Carlson and Tyler O'Neill added long home runs to lead the visiting St. Louis Cardinals past the Cincinnati Reds 10-6 on Sunday afternoon.

Nolan Arenado also homered for the Cardinals, who ended a six-game losing streak to the Reds and showed signs of life after their manager Mike Shildt was ejected in the third inning.

St. Louis reliever Giovanny Gallegos worked out of a bases-loaded jam with none out in the eighth to protect a three-run lead. Cincinnati was just 3-for-17 with runners in scoring position and stranded 13 runners.

Reliever Ryan Helsley (5-4) recorded the final two outs in the fifth for the win.

Sonny Gray (2-6) suffered through his worst outing in a Reds uniform, allowing three homers and eight hits over just 3 1/3 innings, getting tagged for eight earned runs, including six in the fourth inning.

Tyler Stephenson had three hits and reached base in all five plate appearances for the Reds, who finished a disappointing post-All Star break homestand with a 3-6 mark.

Joey Votto's 14th home run -- a three-run shot off St. Louis starter Johan Oviedo -- staked Cincinnati to a 3-2 lead.

Frustration spilled over for the Cardinals in the third inning when Reds third baseman Mike Freeman made a running, leaping throw across his body from foul territory to nab Ryan Carlson at first to begin the inning.

Umpire crew chief Ron Kulpa would not allow Shildt to challenge as Shildt waited to hear from his staff reviewing the play. Shildt argued with Kulpa, resumed the argument after the Cardinals were retired and was ejected.

The Cardinals exploded for seven runs in the fourth as Bader connected for a three-run homer and Carlson drove his 10th homer to the visitors' bullpen in right.

Despite the 9-3 cushion, Oviedo failed to earn his first big league win in his 18th career start (19th appearance) as two of his six walks came in the fifth inning to load the bases. He was relieved by Helsley. Oviedo allowed five hits and three runs while striking out six and walking six in 4 1/3 innings, two outs shy of qualifying for a win.

Helsley fanned Aristides Aquino and induced Kyle Farmer to pop out to short to end the fifth.
