ATLANTA — Ronald Acuña Jr. hit a grand slam in the second inning off Tyler Anderson, pinch-hitter Ehire Adrianza added another slam in the eighth against position player Wilmer Difo and the Atlanta Braves homered seven times in a 20-1 rout of the Pittsburgh Pirates on Friday night.

Austin Riley homered twice for his first multihomer game, and Ozzie Albies, Marcell Ozuna and Dansby Swanson also went deep for the Braves, who became the first team in major league history to have seven or more homers in a game that included two slams, according to STATS.

Acuña had five RBIs and gave Atlanta a 5-0 lead with his 14th homer, which tied the Los Angeles Angels’ Shohei Ohtani for the major league lead. Acuña’s first slam came against Pittsburgh’s Alex McRae on June 10, 2019.

Difo, a 29-year-old middle infielder in his seventh major league season, relieved to start the bottom of the eighth with the Pirates trailing 12-0.

He threw at up to 88 mph, and Adrianza homered on a first-pitch 80 mph offering. Difo allowed three walks and six hits in his one inning, giving up run-scoring singles to Kevan Smith and Guillermo Heredia, Ozuna’s RBI double and Riley’s sacrifice fly.

Difo left with a 72.00 career ERA.

Atlanta avoided falling what would have been a season-worst five games under .500. The three-time defending NL champions had lost seven of their previous 10 games.

Atlanta’s Ian Anderson started against Pittsburgh’s Tyler Anderson, after Ian Anderson started and won at Milwaukee last Saturday in a game the Brewers started Brett Anderson.

This marked the first time since 1900 that a pitcher started consecutive games against different pitchers with the same last name as him.
