The Breakdown

Madison Keys, one of a few possible heir apparents to Serena Williams' American female tennis throne, will get another shot at the Queen Sunday at the US Open. Keys, 20, will try again to derail Williams' quest to win a major tournament in 2015. Williams, 33, beat Keys in straight sets in a semifinal match at the Australian Open earlier this year, the one and only time they've played.

Sunday's match is a fourth-round contest, but no less meaningful for either player. Keys will be trying to advance into the US Open quarterfinals for the first time. Win on Sunday and she can fully expect America to celebrate the official arrival of The Next Generation.

Williams is trying to get closer to a slightly bigger accomplishment: Winning all four Grand Slam tournaments in a calendar year. If she wins the US Open, she'll be the first woman to go four-for-four since Steffi Graf in 1988. The last man to win all four was Rod Laver in 1969. Only five players, man or woman, have accomplished the feat.

Keys, one of the few players on tour with a serve to hang with Serena's, could have a shot against Williams. Under the lights on Arthur Ashe Stadium, the New York crowd might be divided between two Americans. And Williams did show some vulnerability, losing a set to American Bethanie Mattek-Sands in the third round.

So there could be evening theater on Sunday night, but the end act – Serena winning – will likely stay the same.
