BOSTON -- Donavan Brazier and Bryce Hoppel clock top-three American times in history at the 25th running of the New Balance Indoor Grand Prix, the only U.S. stop on the 2020 World Athletics Indoor Tour, at the Reggie Lewis Track and Athletic Center at Roxbury Community College. Results can be found here. In the final event of the day, world 800m champion and 600m world indoor record holder Donavan Brazier (Cadillac, Michigan) followed the pacemaker through the first two laps, passing 400m in 49.62, and then blasted to the front and crossed the line in 1:14.39, the second-fastest time ever. Brazier won by more than five seconds and only his 1:13.77 world best from last year’s Toyota USATF Indoor Championships is faster. After Britain’s Jake Wightman powered to the lead on the fourth lap of the men’s 1,000m, Bryce Hoppel (Larence, Kansas) turned up his pace and slingshotted off the final bend to pass the Brit and win in 2:17.41, moving to No. 3 on the all-time U.S. performer list. In the women’s 2 miles, Elinor Purrier (Montgomery Center, Vermont) overtook Emma Coburn (Boulder, Colorado) with 400m to go and never looked. Purrier won in a new personal best time 9:29.17, while Corburn fell back to third, finishing with a time of 9:32.81. World 100m hurdles champion Nia Ali (Philadelphia, Pennsylvania) made up ground over the final three barriers to win the women’s 60m hurdles in 7.94. Christina Clemons (Montgomery, Alabama) closed well to take second in 7.98. Reigning USATF indoor champion Demek Kemp (Monroe, Georgia) ran a 60m personal best and world-leading 6.50 for the win, speeding away from the field from the start for a .11 margin of victory. In the two-heat 300m final, Gabby Thomas (Cambridge, Massachusetts) won the first heat of the women’s 300m in 36.52 which was held as the fastest time to win. Shamier Little (College Station, Texas) clocked 37.07 to win heat two, good for second overall. Kendall Ellis (North Hollywood, California) crossed the line in 37.36 to finish with the third fastest time. Leading from the gun, Obi Igbokwe (Houston, Texas) clocked 46.50 to win the men’s 400m by almost a full second over Vernon Norwood (New Orleans, Louisiana), who was second in 47.48. Cory McGee (Brighton, Massachusetts) set a personal best to finish fourth in the women’s 1,500m, taking the U.S. lead for 2020 with her 4:06.88. 2019 Toyota USATF Indoor bronze medalist Amina Smith (Bronx, New York) 1.89m/6-2.25 defeated a small field of four in the women’s high jump.
