Ashlyn Krueger vs Janice Tjen — Round of 32 — Japan Women's Open. Krueger won 6-4, 6-4.

Ashlyn Krueger beat sixth seed Janice Tjen 6-4, 6-4 in the round of 32 at the Japan Women's Open. She did not drop serve in the 74-minute match. Krueger is a 22-year-old American ranked WTA No. 68. That put her 21 places below Tjen, the Indonesian ranked WTA No. 47, but the betting market still had Krueger as a slight favorite at 55%. The two had no prior meetings on record. Both sets followed the same pattern. Neither player broke for most of each set, and then Krueger broke once late on. She broke in game 9 of the opener to lead 5-4 and served out the set. In the second set she broke in game 7 to lead 4-3 and served out the match from there. Tjen had only one break point all match, and Krueger saved it. The two players won their first-serve points at almost the same rate: 80% for Krueger and 79% for Tjen. The gap came on second serve. Krueger won 12 of her 15 second-serve points, while Tjen won 12 of 29. Tjen made only 57% of her first serves and hit four double faults, three of them in the first set. That meant Krueger returned far more second serves, and she won 17 of those 29 return points. Tjen saved four of the six break points she faced, but she never generated a sustained threat on Krueger's serve.
