Twins won so they were 3 games back at the end of the game...Detroit was technically still in 1st
Chicago won later in the day...leapfrogged Detroit and the Twins went to 3 1/2 games back
normally when you beat the 1st place team you gain a game
Ya the .5 gb thing bounces back and forth when the top two teams keep jostling.
I prefer to go by the END of DAY standing than the end of GAME standings.
