Alejandro Falla has scored the first big upset of the tournament in the men’s draw at the Australian Open…

The 28-year-old Colombian tennis player defeated American Mardy Fish, ranked No. 8 in the world, in straight sets in their second round matchup.

Falla, ranked 71st in the world, ousted Fish by a score of 7-6 (7-4), 6-3, 7-6 (7-3).

The lefty, who turned pro in 2000, played aggressively from the start, remaining rock-solid throughout the match with his backhand and pressuring the forehand of the American, who committed several unforced errors on key points, especially during the third-set tiebreaker.

“He’s a good player,” Fish, who committed 58 unforced errors, said after the match. “He was up two sets to love against Roger (Federer) at (the 2010) Wimbledon (before losing in five sets). The guy can play. I wasn’t shocked that I was in that position (of down two sets), but … you’ve got to battle. You’ve got to fight. I tried but it didn’t work out.”

Falla’s next round match will be against German player Philipp Kohlschreiber, who currently ranks at No. 41.
