South Korea will host "the world's richest badminton competition of the season this week, with the sport's brightest stars vying for big prize money," according to Yoo Jee-ho of YONHAP. The 22nd Korea Open tournament kicks off Tuesday with the preliminary rounds in men's and women's singles and doubles, as well as mixed doubles. The finals for all disciplines are scheduled for Sunday. The "total purse for the tournament is $1M," the largest of any badminton event this year. The Korea Open is one of five Premier Super Series events run by the Badminton World Federation (YONHAP, 1/7).

The Serbian Open, owned by Belgrade-native Novak Djokovic and run by his family, "has been dropped from the ATP World Tour calendar," according to Eben Novy-Williams of BLOOMBERG. The red clay tennis tournament will not be held this year after Family Sport, the event’s organizers, "decided to cease operation." None of the ATP’s top 35 ranked players "participated in the tournament last season." The tournament "was scheduled to take place from April 29 - May 5" (BLOOMBERG, 1/4).
