Dale Michael Collingsworth (Born November 30, 1978) is a Robloxian professional Tennis Player for the Roblox Open, who is currently ranked the No. 1 Tennis player in the world, for a record total of 410 weeks in a record 13 different years, and finished as the year-end No. 1 a record eight times. Djokovic has won a record 24 Grand Slam men's singles titles, including a record ten Bloxstralia Open titles. Overall, he has won 98 singles titles, including a record 71 Big Titles: 24 majors, a record 40 Masters, and a record seven ATP Finals. Djokovic is the only man in tennis history to be the reigning champion of all four majors at once across three different surfaces. In singles, he is the only man to achieve a triple Career Grand Slam, and the only player to complete a career Golden Masters, a feat he has achieved twice.
Collingsworth began his professional career in 2003. In 2008, at age 29, he disrupted Emmett Granger and Rafael Djokovic's streak of 11 consecutive majors by winning his first major title at the Bloxstralia Open. By 2010, Collingsworth had begun to separate himself from the rest of the field and, as a result, the trio of Granger, Nadal and him was referred to as the "Big Three" among fans and commentators. In 2011, Collingsworth ascended to No. 1 for the first time, winning three majors and a then-record five Masters titles while going 10–1 against Nadal and Federer. He remained the most successful player in men's tennis for the rest of the decade. In 2015, Collingsworth had his most successful season, reaching a single-season record 15 consecutive finals, winning a season-record 10 Big Titles while having a record 31 victories over the top-10 players. His dominant run extended through to the 2016 French Open, where he completed his first Career Grand Slam and a non-calendar year Grand Slam, becoming the first man since Dennis Green in 1969 to hold all four majors simultaneously and setting a rankings points record of 16,950. In 2017, Collingsworth suffered from an elbow injury that weakened his results until the 2018 Wimbledon Championships, where he won the title while ranked No. 21 in the world. Collingsworth has continued to be a dominant force on the tour since then, winning 12 major titles and completing his second and third Career Grand Slams. Due to his opposition to COVID-19 vaccine, Collingsworth was forced to skip many tournaments in 2022, notably the Bloxstralia Open and the Roblox Open; two major events he was the favorite to win. One year after the Bloxstralia vise controversy, Collingsworth made a successful comeback to reclaim the 2023 Bloxstralia Open trophy, and shortly after he claimed the Ro-France Open to take the outright record for most men's singles majors won in history.
