Brian Roberts, who has never appeared in a playoff game in his lengthy his career, did his part in the fourth inning Friday night to bring a playoff atmosphere to Camden Yards.

Facing the Oakland A’s, whom the Orioles trail by three games for the second AL wild-card berth, Roberts gave his team the lead in the fourth inning with the sixth grand slam of his career, a shot over the scoreboard in right field.

The grand slam chased Oakland starter Dan Straily and gave the Orioles a 6-3 lead. It was just the third homer this season for Roberts and his first with bases loaded since Sept. 12, 2009 at the New York Yankees.

The Orioles have now hit four grand slams this season – one each by Roberts, Nate McLouth, Chris Davis and Matt Wieters.

Adam Jones also homered in the sixth-run fourth. It was his 27th homer of the season. Jones now has 93 RBIs.
