Collin Morikawa has controlled the Workday Charity Open for two days, but he needs two more low scores to fend off the list of challengers just a few shots back.
Morikawa separated himself from the field with two of the lowest scores of the first and second rounds. He shot 65 Thursday and followed it up with a 66 Friday.
The American's closest competition comes from Kevin Streelman, who recorded the low score of the tournament Friday, and Justin Thomas. Both players are three shots back.
Hideki Matsuyama, Viktor Hovland and Ian Poulter are among the higher-profile names within striking distance.
