Chennai: Second-seed India's Yuki Bhambri booked a spot in the semifinal of the Chennai Open ATP Challenger tennis tournament with a come-from-behind win over Japan's Yasutaka Uchiyama. The 25-year-old Delhi player allowed his rival to bounce back when in sight of the first set, before regrouping to take the next two on a hot afternoon to post a 5-7, 6-2, 6-4 win. Bhambri failed to convert the chances he had and allowed the sixth-seeded Uchiyama to take the first set. He raised his game in the second with some fluent shots and broke twice to run away to a 5-1 lead before wrapping up set in 28 minutes. The India number one came up with some impressive winners in the decider as the Japanese seemed to wilt and closed out the match with a forehand volley winner. Bhambri will meet Korea's Duckhee Lee in the semifinal.
