PARIS, France (AFP) — Belgium secured a controversial victory in Davis Cup qualifying when Chile’s Cristian Garin refused to continue in the decisive rubber after being painfully knocked down by his opponent, Zizou Bergs, on Sunday.

Elsewhere, Spain made light of the absence of Carlos Alcaraz as they swept past Switzerland.

France also advanced and Hungary survived a second-day fightback by Canada.

In Hasselt, after Belgium won the day’s opening doubles to lead 2-1, Bergs then faced Garin in the first reverse singles.

After holding serve in a marathon 11th game in the third set, an excited Bergs galloped round the court in celebration and raced past the net towards his chair, colliding with Garin and sending him flying.

“It’s truly unintentional,” Bergs said.

“I wanted to go fast to the bench, but I made a completely wrong decision to not wait for the opponent.”

An independent doctor ruled Garin was fit to continue and serve to stay in the match, but he refused. Bergs was awarded the deciding game to win 6-3, 4-6, 7-5.

“It feels really bad to end this way,” Bergs told the Davis Cup website.

“It’s obviously not what you want, to hurt an opponent.”

Bergs said he also apologized to Chile captain Nicolas Massu.

“Terrible situation,” Massu said.

“We’re here to play tennis, to defend our country. Garin is the player who was hit in the eye, who couldn’t continue and now we’re out.”

An ITF spokesperson said: “We understand the emotions attached to this unusual incident, but the final decision was made after consideration of all the facts and unique circumstances around it.”

Belgium will face Australia in the second round.

In Biel, Switzerland, Pedro Martinez and Jaume Munar carved out a hard-fought 6-4, 7-5 win over Dominic Stricker and Marc-Andrea Huesler in the doubles to put Spain 3-0 up.
