Now that the Pittsburgh Penguins have beaten the Nashville Predators for the Stanley Cup, the distinction of longest no-repeat streak in professional team sports goes to Major League Baseball, which has gone 16 consecutive years without a repeat since the 2000 Yankees.
Where does MLB's active streak rank when you factor in all those other team and individual sports that make our viewing lives so compelling each year? Here's the list of the longest active no-repeat streaks ranked from longest to shortest in years, and unless noted, also that sport's longest all-time streak.
45: The Westminster Kennel Club, Best in Show: (1973-2017)
Seven dogs repeated, most recently a dear departed English Springer Spaniel in 1971-72 named Ch. Chinoe's Adamant James.
27: U.S. Men's Open Golf (1990-2016)
All-time: 37 (1952-88). The only surprise is that three-time champion Tiger Woods (2000, '02, '08) never repeated.
23: Little League World Series (1994-2016)
All-time: 26 (1959-84). Long gone are the days when Taiwan seemed to win all the time.
20: The Evian Championship (women's golf) (1997-2016)
Chun In-gee won in 2016 with a 21-under-par total, lowest of any men's or women's major.
16: MLB (2001-16)
Even though the Cubs have been disappointing so far this season, they just need another playoff berth, because it's mostly the same team as the 2016 history-makers.
15: Indianapolis 500 (2003-17)
All-time: 30 (1972-2001). Hélio Castroneves was last to repeat in 2001-02.
15: The Masters (2003-17)
All-time: 29 (1934-65; no event in 1943-45). Only repeats were Jack Nicklaus, Nick Faldo and Woods.
15: The ANA Inspiration (women's golf major) (2003-17)
All-time: 22 (1980-2001). Annika Sorenstam (2001-02) was only repeat in 46 tourneys for LPGA's first major.
15: U.S. Women's Open Golf (2002-2016)
Karrie Webb was last to repeat in 2000-01.
14: WNBA (2003-16)
Sorry, Sparks, but Minnesota wins this every odd-numbered year.
13: Men's World Cup Soccer (1966-2014)
It's going to be harder to repeat starting in 2026 when FIFA expands it to 48 teams.
12: NFL (2006-17)
New England repeated in 2004-05. Could doing it again be the last hurrah for Brady and Belichick?
12: Boston Marathon Women (2006-17; Rita Jeptoo later DQ'd in 2014)
All-time: 16 (1972-87). We only know it will be a Kenyan or Ethiopian in 2018.
10: NCAA Men's Basketball (2008-17)
All-time: 18 (1974-91). "Draft flight" makes it harder than ever. Florida did it last.
10: French Open Women's Tennis Singles (2008-17)
All-time: 15 (1955-69). Garbiñe Muguruza capitalized to deny an injured Serena Williams last year.
9: Boston Marathon Men (2009-17)
All-time: 21 (1902-22). See above comment for Boston Marathon Women.
9: Men's PGA Championship (2008-16)
All-time: 42 (1958-1999). Like The Masters, Woods was last to repeat (2006-07). Previous example was way back in 1936-37 (Denny Shute).
8: British Open (2009-16)
All-time: 22 (1984-2005). Henrik Stinson was first Swede to win in 2016. Can he double up at Royal Birkdale?
8: U.S. Open Men's Tennis Singles (2009-16)
All-time: 12 (1968-79). Remember when we couldn't wait for someone to end Roger Federer's reign?
8: English Premier League Soccer: (2010-17)
All-time: 17 (1960-76, as Football League First Division). Chelsea won back-to-back in 2005-06; will it happen again next season?
6: Monster Energy NASCAR Cup Series Drivers' Championship (2011-16)
All-time: 8 (1949-56). Closing in on the record unless Jimmie Johnson and his No. 48 Chevrolet rally from current sixth place.
6: CFL Grey Cup (2011-16)
All-time: 14 (1983-96). Redblacks hope for Ottawa's first repeat since 1940-41 (different franchise).
5: Women's British Open Golf (2012-16)
All-time: 10 (2001-10). Only Yani Tseng of Taiwan (2010-11) has repeated.
5: College World Series (2012-16)
All-time: 20 (1951-70). South Carolina was the last to win consecutive titles in Omaha. Can Coastal Carolina do it again?
4: NCAA Div. I Football (2014-17)
All-time: Many longer streaks, but muddled due to multiple champions.
4: MLS (2013-16)
All-time: 9 (1998-2006). David Beckham and Landon Donovan were part of the L.A. Galaxy's repeat in 2011-12. Can Seattle do it in 2017?
3: NBA (2014-16)
All-time: 18 (1970-87; record among the 4 major U.S. pro sports leagues). The NBA has remained immune to the no-repeat trend. Just ask LeBron.
3: French Open Men's Tennis Singles (2015-17)
All-time: 21 (1920-41, not contested in 1915-19 and 1940). It only seems like Rafael Nadal wins this one every year, but Novak Djokovic won in 2016.
3: New York City Marathon Men (2014-16; canceled in 2012 by Hurricane Sandy)
All-time: 12 (1996-2007). Actually no man has won in back-to-back years since Kenya's John Kagwe in 1997-98, but we'll count Geoffrey Mutai's 2011 and '13 wins wrapped around the race canceled by Hurricane Sandy.
2: Women's World Cup Soccer (2011-15)
It has only been staged seven times, and the U.S. repeated in 1999 and 2003.
2: Cricket World Cup (2011-15)
Australia has been a dynasty, winning four of the last five.
2: The Rugby Championship (2015-16)
All-time 4 (2009-12). It's New Zealand's party, with the very occasional crasher.
2: U.S. Open Women's Tennis Singles (2015-16)
All-time: 8 (2002-2009). Can Angelique Kerber do it again? Or will it go back to Serena?
1: Formula One World Drivers' Championship
All-time: 25 (1961-84). Repeats are the norm here, and Germany's Nico Rosberg is a work in progress.
1: CONCACAF Champions League
C.F. Pachuca ended a two-year run by Club América, which did not qualify.
1: Wimbledon Men's Singles (Andy Murray won in 2016)
All-time: 13 (1922-34). We'll see next month whether Murray can do it again at home.
1: Women's College World Series (softball)
All-time: 7 (2008-14). Oklahoma won three of the last four and just repeated.
1: Women's PGA Championship (Brooke Henderson last year)
All-time 22 (1962-83)
0: Rugby World Cup
New Zealand became the first repeat champion in 2015. The next one's in 2019.
0: New York City Marathon Women
All-time: 10 (1996-2005). Kenya's Mary Keitany won the last three.
0: Wimbledon Women's Singles (Serena Williams won again in 2016)
All-time: 9 (1934-48; no competition in 1940-45 due to WWII). Serena will be skipping Wilmbledon due to her pregnancy, so we'll get a new champ this year.
All-time: 17 (1999-2016; excludes 2005 strike season). "Dynasty" talk might return at last.
