The Cleveland Indians' Trevor Bauer had to bat on April 6, 2013 against the Tampa Bay Rats because their Designated Hitter was Carlos Santana and they had to move him to Catcher because of them needing to remove Lou Marson, their Starting Catcher from the game. Because they had moved their Designated Hitter to a field position, that voids the Designated Hitter option for the rest of the game for the Indians so the Pitcher has to bat unless they use a Pinch Hitter.
