The Canadian Vasek Pospisil was defeated 6-7 (5), 6-3, 6-2 to Germany’s Jan-Lennard Struff in the first round of the BMW Open on Wednesday.
For his part, Juan Martin del Potro managed his return on stage on clay after an absence of three years with Dustin Brown 7-6 (2), 6-4.
Del Potro won the US Open in 2009 and climbed to fourth globally before being slowed considerably by a major injury to a wrist that has jeopardized his career.
Guests at the Munich tournament, del Potro dominated the tiebreaker in the first set and saved two breaks in the second. He did however have concluded the match at 5-1 service. Brown preserved a match by clearing a backhand winner down the line and then he closed the gap to 5-4.
Brown has however been inconsistent and could not leave his service while trying to level the playing field in the set. He saved two match points before committing a double fault on the third.
Earlier Wednesday, Gael Monfils has also packed up, but because of a groin injury he suffered in training.
The second tournament seeded told that the cold may have played a role in the injury, or “maybe it’s just because I have played many games recently.”
This is the third time in a row that Monfils must withdraw from a tournament on clay because of an injury. He had got a bye to the second round.
The temperature is unusually cold this week in Munich – rain and even snow have led to the interruption.
On the other hand, the Italian Fabio Fognini in fifth continued on to the second round by disposing of Maximilian Marterer 6-3, 6-1, while eighth-seeded Alexander Zverev has defeated Malek Jaziri 4- 6, 6-3, 6-2.
In a second round match, Austria’s Dominic Thiem, seeded No. 3, became the first player to reach the quarter-finals when he beat Colombian Santiago Giraldo 7-5, 6-4. He was joined later by the Croatian Ivan Dodig, who showed the exit to the sixth-seeded Brazilian Thomaz Bellucci, 7-6 (5), 6-3.
