Early in the season, Reds manager Sparky Anderson shifted perennial All-Star Pete Rose to third base, and used a platoon of Foster and Dan Driessen in left. Foster soon won the everyday job with a .300 batting average, 23 home runs and 78 RBIs. With Foster now in left, the final piece of the "Big Red Machine" was in place. The Reds won 108 games that year, tying the World Series champion Baltimore Orioles for the most regular season wins that decade. They dominated the Pirates in the 1975 National League Championship Series, out-scoring their opponent 19–7 to sweep the series in three games. For his part, Foster batted .364 and scored three runs.
