DUSSELDORF, Germany, May 21 (UPI) -- Aljaz Bedene, a late entry into the main draw, collected an upset win Tuesday in the first round of the ATP's Power Horse Cup tennis tournament in Germany.
Davydenko was in charge in the first set but Bedene came back with three breaks to even the match at a set apiece. Bedene dropped just eight points over five games serving in the third set and finished off one of his two break chances to earn a spot in the second round.
No 7-seeded Viktor Troicki rallied for a 3-6, 6-3, 6-4 win over Michael Russell. Troicki was 0-for-3 in saving break points in the first set but lost his serve only once the rest of the match.
Grega Zemlja also came from behind to get past David Goffin 5-7, 6-0, 6-2. He won about two-thirds of the points over the last two sets.
Igor Sijsling took out Evgeny Korolev 6-2, 6-4 in 56 minutes. Sijsling won 70 percent of the points when serving and didn't face a break point.
