No. If the home team is leading after 8 1/2 innings, the game is over. There is no option available for the home team to bat.
They keep batting and the game is played as it normally is. After they make their third out, the home team will get to bat. After the home team makes its third out then it will be determined whether the game ends due to the Mercy Rule. If the home team is 15 or more runs behind the game ends. If the home team is less than 15 runs behind the game proceeds to the 4th inning.
