He's the only player in MLB history to have 40 or more home runs and 60 or more steals in the same year. Two batters after Acuna, Riley's 37th homer gave Atlanta a 3-0 lead before an out was recorded.
Braves starter Charlie Morton was done after one scoreless inning; the right-hander walked two. He departed because of discomfort in his right index finger, according to information from the team. Michael Tonkin (7-2) was the winning pitcher with two innings of relief.
After the game, the Nationals announced that Saturday's game was postponed due to severe weather in the forecast and would be played as part of a split-admission doubleheader on Sunday.

Freddie Freeman had two hits and an RBI for the Dodgers to reach 200 hits for the first time in his career. Freeman became the first first baseman in major league history to reach 200 hits, 20 home runs and 20 stolen bases in the same season.

Manny Machado drove in three runs with a pair of tiebreaking homers in the sixth and eighth innings as host San Diego won its eighth straight game, knocking off St. Louis.

A loser in 10 of the previous 13 and fighting for a National League wild-card spot, reeling Chicago rebounded after allowing 21 runs in losing the previous two games to the Pittsburgh Pirates on this final homestand of the season. Taillon (8-10) helped the cause, though he yielded four of Colorado's six hits and four walks.
However, the Rockies stranded seven men and went 0-for-5 with runners in scoring position while Taillon was on the mound for the Cubs, who also dropped five of the previous seven at home. All-Star catcher Elias Diaz had two hits for Colorado, which has lost five straight overall, and eight in a row on the road.

Yelich, who returned from a back injury and played just his second game since Sept. 9, went 3-for-4 with two home runs, five RBIs and four runs for the Brewers, who are closing in on their third National League Central title in the past six years. Their magic number to win the division is one.
