Marinko Matosevic is fresh out of answers.

“I don’t know,” was the recurring response from the Australian world No.72 after extending his horror grand slam record to no wins from 10 matches.

Matosevic’s latest first-round flop came in a 6-1 4-6 6-4 6-3 loss to Frenchman Guillaume Rufin at Wimbledon on Monday.

The 27-year-old’s record in grand slams is the equal worst of any active player, matched only by Italian Paolo Lorenzi who also lost his 10th match from as many attempts on Monday.

Matosevic admitted coming into the All England Club the winless run was playing on his mind.

He felt a poor serving performance let him down in what he considered a low-quality match against 85th-ranked Rufin.

But asked if the pressure associated with his losing streak had affected him, and what he need to do to break the streak, Matosevic had little to say.

“I don’t know. I really don’t have a clue,” he said.

“It’s pretty shattering right now. I don’t know what I’m going to do.”

After a luckless run in drawing seeded players at his last three slams, including facing David Ferrer in the opening round at the French Open, a clash with Rufin looked to present Matosevic with a golden opportunity to end his losing streak.

But he started poorly, making 14 unforced errors as Rufin raced to a one-set lead in just 27 minutes.

The Australian regained his composure to claim the second set.

The third set was evenly poised before Rufin broke serve late in the set, with a crucial line call angering the Australian.

Despite replays showing the Frenchman had just caught the baseline with a shot to win the game, Matosevic was furious and told the chair umpire the decision was “disgraceful” and “appalling”.

“I just thought it was a very bad match, the standard was very poor, and that just topped it off,” Matosevic said of the incident.

While Rufin will move on to face Spanish 15th seed Nicolas Almagro in the second round, Matosevic is unsure about of his plans beyond the tournament.

“I’ll play the doubles here and then I’ll see if I go to the (United) States or if I take a little break,” he said.

“I don’t know. I’ve been playing a lot of weeks. I’ll see how I feel.”

Matosevic said his desperation to win a grand slam match had made it tough to focus on other ATP events.

“Now I just want to win matches at a slam where I don’t really care about a lead-in event, it’s not good.”
