Did it add up to a problem for Mo Farah?
Not on your life.
The four-time Olympic champion calmly bided his time in the Prefontaine Classic 5,000 meters, took charge of the race with two laps to go, and held off challenges from Ethiopian Yomif Kejelcha and Kenyan Geoffrey Kamworor on the home straight to win.
Farah crossed in 13 minutes, 00.70 seconds. Kejelcha, who made a strong bid from lane 2, was second in 13:01.
