Seven scoreless innings from Tarik Skubal sent Los Angeles back to the playoffs Monday, as the left-hander allowed three hits, struck out nine and walked one against Cincinnati.
The berth is the Dodgers' 14th straight, matching the Atlanta Braves' 1991-2005 run for the longest postseason streak in MLB history.
Skubal has gone at least seven innings in consecutive starts, both against the Reds, giving up two runs over 14.1 innings with 14 strikeouts and three walks.
Dave Roberts and the clubhouse marked the clinch with a brief toast rather than a champagne celebration, reflecting a team still chasing a third straight World Series title after 26 years without one.
Los Angeles has already joined Milwaukee in clinching in the National League and can next lock up its 13th NL West title in 14 seasons along with a top-two seed and first-round bye.
