Harper hit two more home runs Friday night, and he posted the exact same basic stat-line as he did Wednesday afternoon: 3-for-4 with five RBIs.
Here's a more in-depth look at Harper's otherworldly achievements over his past two games:
• At 22 years (plus 204 days) old, Harper is the youngest player in MLB history to hit five home runs in a two-game span, according to the Elias Sports Bureau. He surpassed Mark McGwire, who had done so at the age of 23 years, 270 days.
• Harper is the 34th player since 1914 with five homers in a two-game stretch. He's the first to do so for the Nationals' franchise (meaning no one accomplished the feat for Montreal, either).
• Other players to hit five taters in a two-game span include Ralph Kiner (who did so twice in 1947), McGwire (twice), Stan Musial, Mike Schmidt, Carl Yastrzemski and, in a fun little twist of fate, his current manager Matt Williams. Here's the complete list of players who have done so in the Wild Card era:
Josh Reddick: Aug. 9-10, 2013 Josh Hamilton: May 7-8, 2012* Travis Hafner: July 19-20, 2004 Alex Rodriguez: Aug. 17-18, 2002 Nomar Garciaparra: July 21-23, 2002 Shawn Green: May 23-24, 2002* Barry Bonds: May 19-20, 2001 Geoff Jenkins: April 28-29, 2001 Edgar Martinez: May 17-18, 1999 Manny Ramirez: Sept. 15-16, 1998 Williams: April 25-26, 1997 Albert Belle: Sept. 18-19, 1995 McGwire: June 10-11, 1995

• Harper also is the first Nationals player to record consecutive five-RBI games and consecutive games with at least nine total bases. Before the franchise moved to Washington, both Vladimir Guerrero (2000) and Henry Rodriguez (1996) posted back-to-back games with nine total bags. And Expos catcher Michael Barrett had two-straight five-RBI games in 2002.
• In the past 10 seasons, Harper is the 10th Major Leaguer with consecutive games of at least nine total bases. (And the first since Brett Gardner last July 28-29). He's just the fourth to knock in five runs in back-to-back contests. (Alfonso Soriano had done so most recently, on Aug. 13-14, 2013.)
• Harper is the first player since Edwin Encarnacion last May 20-21 to post consecutive multi-homer games. He's the 23rd player to do so in the past 10 seasons.
• No player has posted three consecutive multi-homer games since the Angels' Jeff DaVanon did so from June 1-4, 2003. (Oddly enough, DaVanon only hit 12 homers that entire season.) It's a feat that's happened only four times in Major League history. Harper could join the club vs. Atlanta today.
• If Harper were to post another multi-homer game on Saturday, he would join Green (2002) as the only players to hit seven home runs in a three-game stretch. In 19 at-bats against Braves starter Julio Teheran, Harper has eight hits, including two taters.
