LOS ANGELES (AP) -- Hideki Matsuyama returned to Riviera and birdied his final three holes to at least stay in range of Sam Saunders at the weather-delayed Genesis Open.
Saunders shot 64 on Thursday and finished the opening round with a two-shot lead.
The first round wasn't completed until Friday morning because of fog. The bigger threat was a huge storm system off California, though Riviera already escaped one wave of rain and wind overnight.
The second round began with players able to lift, clean and replace golf balls in the short grass because soggy conditions are expected the rest of the week.
