Baltimore: Brandon Moss hit a grand slam and Scott Kazmir threw seven scoreless innings as Oakland Athletics beat Baltimore Orioles 11-1 on Sunday in a game that featured another bench-clearing confrontation between the teams.

John Jaso also had four RBIs for the A’s, who took two out of three in the series and improved to a major league-best 22-12 on the road. Baltimore allowed a season-high 11 walks in its most lopsided loss of the year.

For the second time in three games, Orioles third baseman Manny Machado was in the middle of a dugout-clearing scrum.

This time, Oakland left-hander Fernando Abad threw inside to Machado in the eighth. The bat flew out of Machado’s hands and went down the third base line. Both players exchanged words before the benches and bullpens emptied. Machado and Abad were ejected.

On Friday, Machado didn’t like the force of the tag by Oakland third baseman Josh Donaldson and the two had to be separated.

Staked with an early lead, Kazmir (7-2) dominated the Orioles’ line-up. He allowed four hits with seven strikeouts and no walks.

Jimenez (2-7), who signed a four-year, $50 million (Dh183.9 million) deal in the off-season, continued to struggle with his command. He allowed a season-high six runs on two hits with two strikeouts and five walks over just 2 1-3 innings, his shortest outing since April 16, 2013, against Cleveland.

He has not earned a victory since May 8 and has an ERA of 5.01 ERA over 70 innings with Baltimore (31-30).

Jimenez walked three consecutive batters to open the second before Jaso appeared to clear the bases with a shot over the centrefield fence. However, the umpiring crew reviewed the play for 3 minutes, 18 seconds before ruling the ball bounced off the top of the wall for a double. Jimenez then walked Nick Punto to reload the bases before Moss hit his second career grand slam.

Jaso increased the lead to 7-0 in the fourth on an RBI single to left off right-hander Brad Brach. After Brach issued three consecutive walks to load the bases again in the fifth, T.J. McFarland entered and got Jaso to hit into a fielder’s choice that scored Derek Norris before allowing a two-run single to Nick Punto.

The Orioles finally got on the board in the ninth when Chris Davis walked with the based loaded off right-hander Ryan Cook. A single by Kyle Blanks in the ninth boosted the margin to 11-1.
