Zimmerman drove in four runs in his first three at-bats last night in the Nationals’ 9-6 defeat at Oriole Park at Camden Yards in Baltimore.
Sixteen Major League Baseball players have hit four home runs in a single game, with Ed Delahanty of the Philadelphia Phillies in 1896 and Bob Horner of the Atlanta Braves in 1986 achieving the feat and ending up on the losing team.
The latest player to hit four home runs in a game was Josh Hamilton for the Texas Rangers on May 8, 2012. The most recent National League player to hit four homers in a game was Shawn Green of the Los Angeles Dodgers on May 23, 2002.
Zimmerman hit solo home runs in the first and fourth innings and had a two-run homer in the fifth as the Nationals took a 6-2 lead.
The Orioles, who got a home run from Chris Davis in the fourth inning, also had a home run by Nick Markakis in the sixth and homers by Steve Pearce and Davis in the five-run seventh inning.
Davis, who has a MLB-best 19 home runs this season, went 4-for-4 to raise his batting average to .359.
