Task: Question Generation
Input (English): Passage: Another 18-inning contest was played between the Atlanta Braves and the Houston Astros on October 9, 2005. In the 4th game of a 2005 National League Division Series at Minute Maid Park in Houston, Texas, the Braves (who were trailing the series two games to one and facing elimination) took a 6-1 lead into the 8th inning. A grand slam (baseball) by Lance Berkman in the bottom of the 8th brought the score to 6-5, and with two outs in the bottom of the 9th, Brad Ausmus homered to tie the game and send it to extra innings. The score remained deadlocked at 6-6 until the 18th, when the Astros Chris Burke (baseball) (who entered the game in the 9th inning as a pinch runner) homered to left field to win the game and send Houston to the 2005 National League Championship Series against the St. Louis Cardinals. Roger Clemens, who was brought in to pinch hitter in the 15th and pitched the last three innings in relief, was credited as the winning pitcher in the 5-hour, 50-minute contest. Adam LaRoche and Tim Hudson played in both 18-inning games. This one as Atlanta Braves and the other one as opposing sides of one another with Hudson pitching in both games as the visiting teams starting pitcher. It is the longest winner in a potential clinching game in baseball history.
Output (English): How many innings was the game deadlocked for?
