Nationals pitchers must’ve cringed when they went over the Braves scouting reports entering this series and noticed that Freddie Freeman had begun to heat up after a rare extended slump by the big first baseman. So much for their hopes of facing a struggling Freeman and getting through a series without him doing damage.

Freeman had three hits including a first-inning homer off Stephen Strasburg in Friday night’s 6-4, 13-inning win in D.C., the Braves’ sixth win in seven games against the Nationals this season and 12th win in their past 15 games at Nationals Park.

That 12-3 record in Washington is part of a stretch that’s seen the Braves dominate the Nationals, going 24-7 with a 2.01 ERA against them going back to Aug. 22, 2012. Braves pitchers and Freeman’s bat have played very big parts in that remarkable stretch against Atlanta’s top division rival.

Freeman is 17-for-33 (.515) with five doubles, three homers and six RBIs in eight games against the Nationals this season, and has hit .380 with 21 extra-base hits (seven homers), 29 RBIs and a .433 OBP and .634 slugging percentage in his past 37 games against them dating to June 29, 2012. He has 18 multi-hit games in his past 35 games against the Nationals.

Freeman is 9-for-20 with two homers and five walks against Strasburg, who struggles against the Braves like he does against no other team, going 3-5 with a 4.04 ERA in 14 starts including 0-2 in seven starts over the past two seasons (Strasburg was in line for another loss Friday before Craig Kimbrel blew a 4-2 lead in the ninth inning).

Freeman homered on a 2-2 changeup, only the second homer that Strasburg has allowed in the more than 370 changeups he’s thrown this season, according to The Washington Post.
