Johnson continues flying start

Zach Johnson's superb start to 2014 continued at the Humana Challenge in California - but he was upstaged by Patrick Reed in the early stages.

The 2007 Masters champion and three-time Ryder Cup player began the year by winning the Hyundai Tournament of Champions at Kapalua before finishing in a share of eighth at last week's Sony Open, also in Hawaii.

And he was six under with three holes to play in his first round to leave him among the leaders in the tournament formerly known as the Bob Hope Classic, which is being played across three different courses.

Johnson was straight into his stride with birdies at the second and third holes on the La Quinta course. He also birdied the sixth and added two more back to back at nine and 10, before the par-five 13th offered up another shot to Johnson in a so-far blemish-free round.

But even he was outshone by third-year professional Reed, who started on the back nine of the PGA West resort's Palmer course and charged into the lead with five straight birdies from the 16th.

That took him to seven under, one shot ahead of Johnson, fellow Americans Andrew Loupe and Justin Hicks and Canada's Brad Fritsch.

Hicks was the only one of that group playing on the third course, the neighbouring Nicklaus course at PGA West.

South Korea's Charlie Wi, Australian Stuart Appleby and Scot Russell Knox, all playing the Palmer course, led the overseas challenge as they settled among a seven-strong group at five under.
