SEOUL, South Korea (AP) — Masked fans hopped, sang and shouted cheers in baseball stadiums in South Korea on Sunday as authorities began allowing spectators to return to professional sports amid the coronavirus pandemic.

After a weeks-long delay, South Korea’s 2020 baseball season began in early May without fans in the stands amid a then-slowing virus outbreak in the country. Seats in baseball stadiums had since been filled with cheering banners, dolls or pictures of fans.

On Sunday, the Korean Baseball Organization allowed a limited number of fans, or 10% of the stadium capacity, to watch games live. They entered stadiums after their temperatures and smartphone QR codes were checked. During the games, they were required to wear masks and sit at least a seat apart while being banned from eating food and drinking any alcoholic beverages in line with the KBO guidelines.

During a game between Doosan Bears and LG Twins at Seoul’s Jamsil baseball stadium, fans wearing the teams’ jerseys still shouted their favorite players’ names, raised banners and sang fight songs. Some Bears fans jumped from their seats when Choi Joo-hwan hit a two-run home run at the bottom the 2nd inning.

Two of the five baseball games Sunday still continued without fans because they were held in area where stricter social distancing guidelines are in place.
