Mardy Fish is making something of a habit of being the last U.S. man in the field at Grand Slam tournaments.
Not that he's all that thrilled about the distinction.
He did it at the French Open last month, and now he's done it again at Wimbledon, where Fish is into the fourth round for the first time in his career.
"It's lonely. It doesn't feel great. And that's not the goal," the 10th-seeded Fish said Saturday, when his third-round opponent stopped playing because he was in pain. "You know, I want the guys here. So that's a bit of a bummer, I guess."
Fish was leading, 6-3, 6-7 (5), 6-2, 1-1, when 58th-ranked Robin Haase of the Netherlands retired. The only other American man still around, Alex Bogomolov Jr., lost all seven points he played Saturday against 2010 runner-up Tomas Berdych in a match suspended because of rain a day before.
The sixth-seeded Berdych advanced, 6-2, 6-4, 6-3, and now faces Fish.
"Seems like he's pretty comfortable right now here," Fish said. "Brought back, probably, a lot of good memories for him now. He seems to be rolling."
Fish is, too.
Against Haase, he saved all three break points he faced -- Fish has only lost serve once through three matches -- and won 41 of 53 points he played at the net. Fish accumulated 20 break points on Haase's serve, converting three.

A year ago at Wimbledon, Roger Federer lost the very first two sets he played. While he came back to win that first-round match, he was gone by the quarterfinals.
So far in 2011 at the All England Club, the six-time champion hasn't dropped a set. And he says he's focused on making sure he takes every foe seriously.
"I've learned my lesson early on in my career, where I used to underestimate opponents because of the way they played, the way their techniques worked out, or just said, 'Against this guy, I can't lose on grass.' Next thing you know, that's what happens," Federer said Saturday.
He moved into the fourth round at the grass-court Grand Slam tournament by beating 2002 runner-up David Nalbandian, 6-4, 6-2, 6-4.
Federer is trying to tie the Wimbledon record of seven men's singles titles.
