How do you define dominance? How do you compare the achievements of athletes all around the world, in different leagues, in different sports?
There's no exact formula, but we're once again giving it a shot by ranking the most dominant athletes in the world.
Every aspect counts — athletes who crush opponents with power, speed, or technique, athletes who win individual accolades, athletes who reach the pinnacles of their sports, both individually or with a team.
Our list skews toward recent performance: while longevity and history counts, we favored athletes who have had successful years or stretches since our last edition in 2016.
The result is a wide variety of competitors in a wide variety of sports — football, basketball, baseball, hockey, soccer, golf, tennis, swimming, gymnastics, track and field, ice skating, and more.
Take a look below.

50. Gwen Jorgensen

American triathlete
Age: 31
Jorgensen dominated at the 2016 Rio Olympics, winning the triathlon by 40 seconds to bring home the U.S. its first-ever gold in the event. Currently pregnant, Jorgensen hasn't competed in 2017, but prior to the Olympics, she won five of seven international events in 2016 and had won 15 of 17 events dating back to July 2014.
49. Justin Tucker

Baltimore Ravens kicker
Age: 27
Justin Tucker went 24/24 on kicks from 40+ yards last year, including an absolutely astonishing 10/10 from 50+. That's as good as any kicker has ever been from that distance, and effectively extended the Ravens' scoring range ten yards further than any other team in the NFL. Kickers don't get enough love for their value — no play more commonly decides a game in its final seconds than a field goal attempt from less-than-ideal field position. In that situation there's no player you'd rather have than Justin Tucker.
48. Marta

Orlando Pride forward
Age: 31
Time hasn't slowed down Marta. The 31-year-old forward was a finalist for Ballon D'Or in 2016, making her a top-three nominee for the prestigious award in 12 of the last 13 years, including a five-year stretch of winning it. Back in the NWSL this year, she leads the Orlando Pride in goals and assists.
