The Cardinals game on Friday night with the Reds was suspended in the 8th inning due to heavy rain. The game will pick back up Saturday just after noon with the score tied at 2-2. The Pirates beat Milwaukee 6-3, so the number remains unchanged.
The Royals gave up two grand slams in their series opener at Baltimore and lost on Friday night 14-8. The Twins topped the White Sox in Chicago 6-2. The Royals still own a ten-game lead over Minnesota, but the magic number stays put.
The magic number is determined by taking 163 and subtracting the number of wins for the Cardinals (or Royals) and subtracting the number of losses for the Pirates (and Twins) respectively.
