Question: What team was atop the final College Football Playoff rankings the season Alabama defeated Georgia on overtime to win the national title? Passage 1:Alabama, coming off a national title game loss to Clemson in 2016, began the year ranked first in the AP Poll. The team opened the year with a victory over then-No. 3 Florida State in the Chick-fil-A Kickoff Game, which was the highest ranked season-opening match-up in the history of the AP Poll. Alabama won their first 11 games convincingly, but fell on the road to rival Auburn in the regular season finale, and since the two teams were tied atop the SEC West Division at 7–1, Auburn advanced to the 2017 SEC Championship Game on the head-to-head tiebreaker. Alabama fell to number six in the rankings leading up to conference championship weekend. In the final College Football Playoff rankings of the year, 11–1 Alabama controversially rose to number four after sitting idle, ahead of 12–1 Wisconsin, 11–2 Big Ten Conference champion Ohio State and 12–0 American Athletic Conference champion UCF. This earned Alabama a place in the national semi-final to be played at the Sugar Bowl against first-seeded Clemson, the third consecutive playoff meeting between the two schools. Alabama won by a score of 24–6 and advanced to the 2018 College Football Playoff National Championship against SEC champion Georgia. The Crimson Tide pulled off a dramatic come-from-behind overtime victory to win the game 26–23 and the national title.
 Passage 2:John Robert Isner (born April 26, 1985) is an American professional tennis player who has been ranked as high as No. 8 in men's singles by the Association of Tennis Professionals (ATP). Considered one of the best servers ever to play on the ATP World Tour, Isner achieved his career-high singles ranking in July 2018 by virtue of his maiden Masters 1000 crown at the 2018 Miami Open and a semifinals appearance at the 2018 Wimbledon Championships. He has also twice reached the quarterfinals at the US Open in 2011 and 2018, the latter of which helped qualify him for his first ATP Finals appearance later that year. He currently has the second-most aces in the history of the ATP World Tour, having served 11,969 aces. At the 2010 Wimbledon Championships, he played the longest professional tennis match in history, defeating Nicolas Mahut in a total of 11 hours and 5 minutes, played over the course of three days.
