Question: Which of the players that Serena Williams played in the 1997 qualifying rounds is the oldest? Passage 1:Vermeil signed with the Kansas City Chiefs on January 12, 2001 despite his retirement following the Super Bowl win with the Rams. His first season with the Chiefs was substandard, finishing with a 610 record, their worst record since 1988. Vermeil and the Chiefs made some major changes for the 2002 season, where the Chiefs would improve to 88. The Chiefs had the NFL's best offense in 2002, led by Priest Holmes, Trent Green, Tony Gonzalez, Dante Hall, and offensive linemen Willie Roaf and Will Shields. In 2003 the Chiefs started the season 90 and finished with a 133 record, making the playoffs and winning the AFC West. They also had the NFL's top ranked offense for the second straight year. The Chiefs went 79 in 2004, even though they had the NFL's top ranked offense for the third consecutive year under Offensive Coordinator Al Saunders. The Chiefs performed poorly due to their soft defense, which was ranked 31st out of 32 teams in the league.
Passage 2:The Black Horse Pike heads south from US130 in Camden as a four-lane, divided highway comprising Route168, which continues north of US130 on Mt. Ephraim Avenue. It heads south and interchanges Route76C, which heads west and provides access to Interstate 76 (I-76) and the Walt Whitman Bridge. It passes through Haddon Township with many jughandles at intersections. It then passes through Mt. Ephraim, where the road was restriped in the late 1990s reducing it from four lanes to two, and enters Bellmawr, where it interchanges with exit 28 of I-295 and exit 3 of the New Jersey Turnpike (NJTP). It then enters Runnemede, where it crosses Route41 and County Route 544 (CR544). It then heads into Gloucester Township and interchanges with Route42. It continues south, passing through Blackwood, where it intersects CR534, and then widens back into a four-lane, divided highway. It then heads toward the southern terminus of the NorthSouth Freeway (Route 42) and the western terminus of the Atlantic City Expressway, where Route 168 ends and the Black Horse Pike becomes Route 42.
Passage 3:Williams played the qualifying rounds of her first three tournaments of 1997, in the first round of State Farm Evert Cup, third round of Acura Classic and second round of European Indoor Championships, to Alexia Dechaume-Balleret, Magui Serna and Dominique Monami respectively. She then qualified for her first tour main draw when she defeated Magui Serna in the final round of qualifying at the Kremlin Cup, but lost in the first round of the main draw to compatriot Kimberly Po. She then entered the Ameritech Cup as a wild card and ranked no. 304. She earned her first main draw win against then world no. 27 Elena Likhovtseva in straight sets. In the next round, she upset world no. 7 Mary Pierce in two tight sets, with Williams failing to serve it out in the twelfth game of the second set but eventually won in a tie-break. In the quarterfinal she upset world no. 4 Monica Seles easing through the second and third sets, recording her first career wins over top 10 players and becoming the lowest-ranked player in the open era to defeat two top 10 opponents in one tournament. She ultimately lost in the semifinals to world no. 5 Lindsay Davenport 4-6 in both sets.
