Heyward, who was moved from right field to center as part of an outfield reshuffling, had his own problems. Twice, he overthrew the cutoff man on throws to the plate, allowing runners to advance. Just to add to Atlanta's outfield woes, Justin Upton wasn't even close on a sliding attempt when Ellis doubled down the right-field line in the fourth.
He wound up scoring on Mark Ellis' two-out single, stretching the lead to 5-0.
Kershaw struggled with command of his fastball, but worked more off his breaking pitches and made it look easy against the free-swinging Braves.
"Strikeouts just kind of happen," he said. "It's not something I'm trying to do. I'm just trying to get outs as fast as possible."
Gattis, one of Atlanta's most pleasant surprises during the regular season, had a miserable night in his postseason debut. He ended the second by somehow getting doubled off first on a lazy fly to short right field.
Dan Uggla watched it all from the dugout. The three-time All-Star was left off the Braves' playoff roster after a dismal season in which he batted just .179 with a franchise-record 171 strikeouts.
Uggla wasn't the only big-money flop for the Braves, who had to juggle their outfield because of B.J. Upton's season-long slump. After signing a five-year, $75.25 million deal during the offseason, he batted just .184 and was finally benched late in the year. Merely a backup in the playoffs, he took a called third strike as a pinch-hitter in the fifth and walked slowly toward the dugout to a chorus of boos.
"It just got away from us," Braves catcher Brian McCann said.
NOTES: The Dodgers put Ethier on their 25-man roster even though he can likely only be used as a pinch-hitter because of an ankle injury. He came up in that role in the eighth, batting for Kershaw and grounding out to first base. ... After Medlen struck out the first three hitters of the game, Los Angeles didn't have another 1-2-3 inning until the seventh against Braves rookie Alex Wood. ... Skip Schumaker started in center field for the Dodgers and drove in the first run with a sacrifice fly in the second. ... Brian Wilson and Kenley Jansen finished up with one scoreless inning apiece. Jansen struck out the side in the ninth.
