Former No. 1 Thomas Muster was easily beaten 6-3 6-0 by Philipp Kohlschreiber at the Cup Bet-at-Home, on Monday in the final game of his comeback.

The 43-year-old Austrian returned to professional tennis in 2010 after, 11 years later, but has won only one of 15 main-draw matches at the lowest level of the Challenger tour and lost both main-draw matches at ATP level. He is still ranked outside the top 1,000.

“I don’t plan to keep on playing forever but I am still very much enjoying it,” Muster said.

The result means that Jimmy Connors remains the oldest player to win an ATP matche after reaching the quarterfinals in Halle, Germany, in 1995 at the age of 42

Muster, who won the French Open in 1995, was on his favorite clay-court surface against Kohlschreiber, but the fifth-seeded German raced into a 3-0 lead before Muster managed a break and reduces the deficit to 3-4 shortly afterward.

Kohlschreiber did not concede another game and scored his first match point after just over an hour of play.

“To lose the second set 6-0 is fine with me,” Muster said. “It just shows that Philipp did not give away any points.”

Kohlschreiber, who won his third career title in Halle in June, next play Albert Montanes, who defeated fellow Spaniard Javier Marti 6-3, 6-2.

Sixth-seeded Andreas Seppi eased past Uzbekistan's Denis Istomin of Uzbekistan 6-2, 6-2, and Spain’s Albert Ramos beat Igor Andreev of Russia 6-0, 6-7 (2), 6-4 to reach the second round.

Ramos, coming off his first career semifinal in Umag, Croatia last week, will next play eighth-seeded fellow Spaniard Pablo Andujar, who beat Lukas Rosol the Czech Republic 3-6, 6-3, 6-3.

Two other Spanish players after Pere Riba Advanced shot down Romanian Victor Hanescu 7-6 (3), 6-4, and Daniel Gimeno-Traver defeated wildcard Dominic Thiem 6-4, 6-2 first game in Austria in the ATP World Tour.
