Masai Russell: Olympic champion casually drops new American Record to win 100mH event at Grand Slam Track

The second meet of the Grand Slam Track in Miramar, Miami began with a bang after Olympic champion Masai Russell blazed to an exceptional new American Record of 12.17s (2.0m/s) to win the women's 100mH event.

Running against a formidable field of hurdlers, Russell took the race with brilliant form from the start and held on to the finish line to clinch the famous victory over in-form Tia Jones, who also clocked an outstanding new Personal Best (PB) of 12.19s for second, while Ackera Nugent was third in 12.34s.

With their jaw-dropping times, Russell and Jones dipped under the previous American Record of 12.20s set by Keni Harrison in 2012, and their marks are the second and third fastest legal marks in history behind Tobi Amusan's world record of 12.12s.

It is also the first time ever two women have broken 12.20s in one race, making an exciting watch on what to expect for the rest of the season.

Russell and Jones will be back to race in the 100m on Day 2 (Saturday), aiming to snatch the win in the women's short hurdles category and clinch the highly coveted winning prize of $100,000.
