Thierry Siewe Yanga (Montgomery Blair)
WATCH Siewe extend his unbeaten streak in the 800 with his win at the Montgomery County Championships!
Aside from last year's New Balance Nationals Emerging Elite event, he is undefeated in the 800 dating back to the 2015-16 indoor season. His absence at the 4A West Regionals opened the door for a breakout performance by Northwest's Chase Osborne, but Siewe will still be the favorite in any 800 he runs come springtime.
