2019 WPA World Ten-ball Championship

The 2019 WPA World Ten-ball Championship was a professional pool tournament for the discipline of ten-ball organised by the World Pool-Billiard Association (WPA) and CueSports International. It was the fifth WPA World Ten-ball Championship; the previous championship was held in 2015. After plans for an event in both 2016 and 2018 to be held in Manila fell through, a 2019 event at the Rio All-Suite Hotel & Casino in Las Vegas as part of a three-year deal for the event to be played in the United States was agreed. The event was held concurrently with the Billiard Congress of America's National Ten-ball event from July 22 to 26. The event was sponsored by cue manufacturer Predator Group.

The competition featured 64 participants, selected according to world and continental pool rankings as well as qualifying events. The tournament was played as a double-elimination bracket until 16 players remained, at which point it changed to a single-elimination format. Ko Ping-chung, representing Chinese Taipei, won the event, defeating German player Joshua Filler 10–7 in the final. Ko's brother Ko Pin-yi, who was the defending champion, lost to Filler 10–8 in the semi-final. The event featured a prize fund of $132,000, the winner receiving $30,000.

Format
The WPA World Ten-ball Championship is a professional ten-ball pool tournament first held in Florida in the 2008. The 2019 event was the first official world ten-ball championship since the 2015 WPA World Ten-ball Championship after plans for events in both 2016 and 2018 held in Manila, Philippines fell through. In December 2018, event organisers CueSports International partnered with the World Pool-Billiard Association (WPA) to stage the event with sponsorship from cue manufacturers Predator Group. The event was held at the Rio All-Suite Hotel & Casino in Las Vegas, Nevada, which had also hosted the 2019 WPA Players Championship earlier that year and had plans to host the ten-ball event for three years. The event was the first pool world championship held in the US since 1997, and the first ten-ball world championship held outside of the Philippines. The tournament was played alongside the Billiard Congress of America's National Ten-ball Championship. The event contributed points towards the WPA world rankings.

The event featured 64 players, entries being selected from ranking lists for players tours, such as the Euro Tour and the Asian Tour, and 16 qualifiers who had won events held in Las Vegas from June and July 2019. The tournament was played with a double-elimination knockout structure until 16 players remained, when it became a single-elimination format.

The match was temporarily halted after the venue's fire alarm sounded, but both players opted to play on; after the match, Pagulayan commented "We don't care about that.

After the match, Ko commented "I was criticizing and questioning myself, and that's why I didn't do well on the breaks [...] I wasn't very lucky. Every time that Filler missed, I didn't have a good position to shoot."

In the second semi-final, Ko Ping-chung reached the final with a 10–3 win over Masato Yoshioka. Yoshioka won the opening rack of the match, but after a series of errors, lost the next four racks to trail 4–1. He tried to recover, capitalizing on Ko to cut the deficit to 5–3, but Ko won the remaining five racks to win the match. As a relatively unknown player, Yoshioka commented "My main objective was to just get the experience internationally, but when I got to the semi-finals, I felt a lot of pressure. That's why I didn't play in a way that I want[ed] to play."

In the final Ko Ping-chung defeated Joshua Filler 10–7. Filler took an early 3–1 lead, at which point Ko took a comfort break. Ko later tied the match 5–5, and took the lead for the first time at 6–5.

I didn't know if I could beat him but I just wanted to try my best."

The win was the first major championship win of Ko Ping-chung's career, his best previous major results having been semi-finals. The event mirrored the 2015 WPA World Ten-ball Championship, which was won by Ko Pin-yi while Ko Ping-chung had lost in the semi-final. When asked about the 2015 outcome, Ko Ping-chung answered "I was happy for my brother, but I think if I would have been the winner that may have been better".
