BALTIMORE -- For the first time in American League history, a team opened with back-to-back-to-back home runs. Orioles Ryan Flaherty, J.J. Hardy and Nick Markakis staked Baltimore to a 3-0 lead in the bottom of the first inning of a 6-5 win in Game 1 of Thursday's doubleheader against Texas.
Atlanta's Rafael Furcal, Mark DeRosa and Gary Sheffield did it May 28, 2003, and San Diego's Marvell Wynne, Tony Gwynn and John Kruk accomplished the feat on April 13, 1987.
