Rivera went 2-for-4 with a solo home run and an additional RBI in Wednesday's extra-inning loss to Boston.
Rivera put Baltimore on the board in the third inning with a solo shot to left field. He gave the team another lead with an RBI single in the 10th, but Boston emerged with the victory on a Tyler O'Neill walk-off homer in the bottom of that frame. It was a rare opportunity for Rivera to produce, as he's started just twice in the Orioles' past seven games.
