Flores and Aoki Break MR - Kanto Regionals Day Two Highlights

Following up her collegiate record 51.71 last weekend in Shizuoka, Arie Flores (Nittai Univ.) lit up a windy 2nd day of the Kanto Region University Track and Field Championships with a solo 52.82 MR, over half a second under the old record and beating 2nd place by a second and a half. With her Japanese citizenship transfer from Peru still in processing it's only a matter of time before Flores officially erases the 2008-era 51.75 m NR.

She wasn't the only athlete to set a new MR despite the windy conditions. The D1 women's and men's 1500 m finals were nothing special time-wise, but in the D2 men's race Ryuto Aoki (Rikkyo Univ.) set a D2 MR 3:44.92 for the win, with the next 3 all running new PBs. Women's hammer throw 3rd-placer Misaki Takako (Tsukuba Univ. Grad School) also set a D2 MR with a throw of 54.37 m.

But except for Flores, the races of the day were the D1 and D2 men's 100 m finals. With a massive +4.5 m/s tailwind, #1-ranked Hiroki Yanagita (Toyo Univ.) ran 9.95 to win, with 2nd-placer Yuta Sekiguchi (Waseda Univ.) running 10.02 and 3rd-placer Riku Oishi (Toyo Univ.) 10.04. The fun kept coming in the D2 race, where Yuhi Mori (Daito Bunka Univ.) ran 9.97 with a +3.9 m/s tailwind. With that kind of tailwind those times don't really mean much, but it was noticeable that in both races there was a pretty significant drop-off in times behind the people above, D1 4th-placer Kaito Kuroki (Chuo Univ.) running 10.18 and D2 runner-up Ryunosuke Kitahara (Daito Bunka Univ.) 10.22.

Kanto Regionals continue through Sunday.
