Djokovic on his best behavior in 1st match since US Open default

ROME (AP) Novak Djokovic behaved better Wednesday in his first match since being defaulted from the U.S. Open.

The top-ranked Serb was mostly courteous with the chair umpire during a 6-3, 6-2 win over local wild-card entry Salvatore Caruso in his opening match at the Italian Open.

When the umpire came down to inspect a ball mark on the red clay early in the first set and made an overrule in Caruso's favor, Djokovic just replied, ''Yup,'' and rubbed out the mark with his red sneaker.

When Caruso impressed him - the Italian hit 13 winners to Djokovic's 12 - Djokovic said, ''Bravo.''

Djokovic's only testy moment came during the third game of the second set, which went to deuce seven times before Djokovic finally broke Caruso's serve. As the game wore on, Djokovic appeared bothered by crowd noise, even though the Campo Centrale is empty of fans this year because of the coronavirus pandemic.

The only people inside the stadium were coaches and others working at the tournament.

''Which ones?'' the umpire asked Djokovic, trying to figure out who was bothering him.

Djokovic replied curtly: ''There's 10 people in the stands.''

On Monday, Djokovic said that he had learned ''a big lesson'' after he was thrown out of the U.S. Open 10 days ago for unintentionally hitting a line judge in the throat with a ball.

Djokovic, a four-time Rome champion, next faces either Italian qualifier Marco Cecchinato or Filip Krajinovic.

Later, nine-time Rome champion Rafael Nadal was to make his return to competition after a seven-month absence against Pablo Carreno Busta.

Also in the second round, Rome resident Matteo Berrettini defeated Argentina Federico Coria 7-5, 6-1, and Marin Cilic beat sixth-seeded David Goffin 6-2, 6-2.

In the women's tournament, Montenegrin qualifier Danka Kovinic eliminated sixth-seeded Belinda Bencic 6-3, 6-1.

The clay-court event, which was rescheduled from May because of the pandemic, is an important warmup for the rescheduled French Open, which starts in 11 days.
