Noah Lyles took second in the 100m on Boylston Street at the Boost Boston Games on Sunday, minutes after Wayde van Niekerk, the 400m world-record holder, eased up with tightness in his right hip.
Lyles, an Olympic medal contender in the 100m, 200m and 4x100m, finished second to countryman Isiah Young. Young clocked 9.94 seconds, while Lyles registered 10.10.
The world 200m champion Lyles’ best 100m time in four races this year is 10.08, two tenths behind Olympic favorite Trayvon Bromell. Lyles said before Boston that he needed more races in the 100m to get comfortable ahead of the Olympic Trials in one month, when the top three qualify for the individual Olympic race.
