American tennis player Jack Sock absolutely believes Scot Andy Murray can become a dominant force again. Murray, 30, hasn't played at an ATP event since July. Back then, the Scot lost in the Wimbledon quarter-finals to big-serving Sam Querrey. Murray, who was plagued by a hip injury during the match, has been healing the injury for a couple of months now. The 30-year-old hoped to continue his 2017 campaign but ultimately decided to take a lengthy break and shut down the year.

The greats Roger Federer and Rafael Nadal have had an exceptional 2017 campaign so far.

Federer shut down his 2016 season after Wimbledon as he underwent a knee surgery. Nadal wasn't satisfied with his 2016 campaign and finished his season earlier as well. Federer and Nadal each captured two Grand Slam titles and a couple of Masters 1000 titles this season.

"I think if Roger and Rafa can bounce back in the way they both have done this season, with the injuries they had, then Andy (Murray) certainly can," Sock told the London Evening Standard Sport.

Murray to play again in the ATP Finals

Murray, a three-time Grand Slam champion, didn't win a Grand Slam title in 2017. Murray is also set to miss the upcoming Nitto ATP Finals. The 30-year-old has played regularly at the ATP World Tour Finals event since 2013.

The London crowd won't be seeing home-favorite Murray among the eight players competing at the ATP Finals at the O2 Arena. Sock thinks Murray will still be in contention to win Major titles and make more appearances at the prestigious London event.

"I'm sure he (Murray) will have many more times playing at the O2 and I see no reason why he can’t be going for Grand Slam wins next season," Sock added, per the Standard Sport.

Murray claimed his maiden ATP Finals crown a year ago. Unfortunately, the 30-year-old won't be defending the title he earned in 2016. The locals would love to have Murray at the event, opinioned Sock.

"Obviously for the home fans, Andy's a big loss, plus he:s one of the good guys," Sock praised Murray, per the Standard Sport.

Murray sends positive signs

Murray made his first public appearance since Wimbledon this past Tuesday. The Scot clashed against Swiss Federer in a charity match held at Glasgow's SSE Hydro. Federer beat fan-favorite Murray in a three-setter. Sock was happy to see Murray hit the court once again. The three-time Grand Slam winner hopes to be ready for the 2018 season.
