Topspin: Halfway to a true Grand Slam and, as she prefers to see it, three-quarters of the way to a self-styled "Serena Slam," having won the past three major tournaments in a row. ... Steffi Graf in 1988 was the last woman to win all four Grand Slam tournaments in a single season. ... A five-time champion and two-time runner-up at Wimbledon, Williams hasn't been past the fourth round either of the last two years at the All England Club. ...

Topspin: Left-hander with a big serve and flat forehand consistently produces her best Grand Slam results on the grass at the All England Club, making it to at least the quarterfinals each of the last five years, including two titles in that span. ...

Major Titles: 0 — Best: F, at Wimbledon ('13)

Last 5 Wimbledons: '14-QF, '13-F, '12-QF, '11-SF, '10-DNP

Topspin: Never as good on any surface as she is on grass, where her booming serve becomes especially effective. She hit a record 27 aces in a victory at a Wimbledon tuneup tournament at Birmingham, England. ... She also holds the record for the fastest recorded serve, reaching 131 mph (211 kph) in a 2014 match.

Topspin: Big serve and forehand should work well on grass, although she fared poorly in pre-Wimbledon play this year. ... Seven-time major champ John McEnroe, now an ESPN analyst, says about Keys: "If she can figure out the movement on the court, she's going to have a shot at going deep at an event like Wimbledon."
