null[URL=null]Greatest Career Records

Chris Evert's winning a Grand Slam title 13 consecutive years.

Tennis records - hmmm.

Martina Navratilova's 83-1 record in 1983.
Or her 70+ matches in a row. Not even Graf could top that. (Although in fairness Helen Wills Moody won 152 matches in a row, Alice Marble went 90-0 in 1939-40, and Suzanne Lenglen lost a grand total of 1 match -by default- from at least 1919 until the end of her amateur and professional careers.
Her 9 Wimbledon crowns is a nice record that may stand for a while. And her 167 singles titles and 162 doubles titles is quite a feat.

Chris Evert won 90% of her career matches.

Margaret Court's 62 overall major titles. Her 1970 Grand Slam year is pretty impressive 104-6, 21 of 27 titles.

Maureen Connolly's 9 major titles without a loss, 1951-4.

Bill Tilden's 8 straight US Open finals (the final six being wins).

John McEnroe was something like 84-3 in 1984.

For four years in a row (1978-80), Bjorn Borg won the French AND Wimbledon.

Rod Laver completed the Grand Slam not once, but twice.

I think someone will break Aaron's HR mark. The way the balls are flying out of the parks now, you just need someone to get off to a really good start in his career, then start cranking out 60-plus HR years like Sosa has.

And Michael Jordan could've equaled or bettered Russell's 11 titles in 13 years, had he not retired twice and just stayed with the Bulls for his entire career.

Without question the record that CANNOT be broken is Cy Young's 511 career wins....considering the limited number of starts available today (due to 5 man rotations, starters pulled earlier in games for "set-up" men and closers who blow games for them -- can you say Armando Benitez, Bobby V.), that record is untouchable!....a pitcher would have to AVERAGE over 25 wins per year for 20 years to equal that mark -- especially considering today's salaries, you won't find pitchers who last for 27 years in the majors anymore like Nolan Ryan did.

Margaret Court won 66 career Grand Slam titles, and as both men and women are playing less doubles and mixed in the Grand Slams, I believe that is a record that can't be broken! Chris Everts 125 clay court wins will also be hard to beat, as will Martina Navratilova's single season record of 87-1, I also think Lottie Dodds winning Wimbeldon at 14 are pretty safe. I think Rod Lavers winning 2 Grand Slams will be the hardest of all to beat! With honorable mention To Evonne Goolagong-Crawley winning Grand Slam titles as a single female and later as a mother! (Steffi any fancy of returning?)
