Third baseman Travis Shaw has to hit clean up every time the Milwaukee Brewers face a right-handed starter. In 2017, Shaw posted a .275/.351/.551 batting line from the cleanup spot. He also managed a .281/.361/.530 slash line against righties.
His OPS fell to .776 against lefties last year. That’s an improvement over 2016, and he has to play at third every day for the Milwaukee Brewers. However, he needs to slide down the batting order when he faces a lefty.
Domingo Santana makes sense in the clean up spot against left-handers. Santana bats right-handed, so he has the advantage against lefties.
