So my thought was Boyd is a 38% GB pitcher and the Brewers are a 44% GB hitting team. The only lefty in their lineup with a high pull% is Yelich but he has a 69% GB rate. Their RH power hitters are all pull hitters. Obviously this scenario only matters if Tucker is even healthy enough to play RF. You would also lose Tucker's bat once you replace him later in the game for defense, but backup QB Mo Baller is 2-2 with 4 RBIs in my made up scenario so you won't need to worry about offense when the Cubs are up huge in the later innings.
