The howling winds that whipped through Flushing all afternoon had largely died down, but there was another storm brewing in Arthur Ashe Stadium last night. When all was said and done, Andy Roddick had been blown out of the U.S. Open.

Roddick, the defending champion, lost to 22-year-old Swede Joachim Johansson in five sets, 6-4, 6-4, 3-6, 2-6, 6-4 after climbing back from a two-sets-to-none deficit. Serving at 4-5 to stay in the match, Roddick fell behind love-40 and then saved two match points. Johansson, who showed little sign of nerves throughout the match, worked his way into a rally the next point, miss-hit a forehand that landed in, and won it when a Roddick backhand went long. Roddick, who has lost all three of his five-set matches this year, had been the last American standing in the men’s draw.

Johansson, who had never beaten Roddick in four matches, including three as a junior, wasn’t even supposed to be at the Open this week. He lost in the first round last year and said he had plans to play golf with his father in Scotland. “I had to change my plans,” he said.

Johansson will play Lleyton Hewitt in the semifinals tomorrow. Johansson dates Hewitt’s sister, but said neither he nor his girlfriend will feel conflicted tomorrow.

“She’s going to go for me for sure,” he said.

Roddick had numerous chances to take control, but converted only three of 15 break point opportunities. Johansson, on the other hand, won three of five despite being essentially helpless against Roddick’s booming serve most of the time. Roddick even won more points: 152 to 128.

For much of the night, Roddick looked like he was playing against a better version of himself. Johansson, Roddick’s Swedish doppelganger, stood four inches taller, his hair was blonde, his serve was just as deadly, and his forehand couldn’t miss. For two sets, the doppelganger was winning. Big.

Johansson got a break in the first set when Roddick double faulted. Then the rains came, sending the players to the locker room for an hour. Johansson returned undistracted and undeterred and closed out the set.

Roddick poured it on in the second and third sets, firing aces (he finished with 34) and returning Johansson’s serve more consistently. Through much of the match the American stood well behind the baseline, and he had a few openings in the fifth set but could not capitalize. Johansson had one and took it, and when he was done, he walked off the court as easy as the breeze he blew in on.
