John Cook, who owns a home in Corona del Mar, had a bit of a wild round Friday.

He had five of his six bogeys on the front nine, and then birdied the last four holes to finish one-over and tied for 47th.

Greg Hopkins, a Newport Beach resident, is playing in the Toshiba Classic once again on a sponsor's exemption.

Hopkins played in the same group as Toledo and Jim Rutledge.

Hopkins shot eight over and is at the bottom of the tournament.

Frost's bogey-free 63 is his best score in 10 career rounds at the Toshiba Classic, and it's his second-lowest in his Champions Tour career.

Toshiba Classic defending champion Loren Roberts opened with a 2-under 69 (tied for 17th), marking the fifth straight year he's started the Toshiba Classic with a round in the 60s. Roberts' 69 also extends a streak of sub-par scores at Newport Beach to 11 straight rounds.

Bart Bryant withdrew from the tournament before the round due to the flu and was replaced by Don Pooley. Pooley made his first start in a Champions Tour event since last year's Toshiba Classic and carded a 3-over 74.

In addition to Frost, Chien Soon Lu (67), Peter Senior (68), Mark Brooks (68), Wayne Levi (69) and Olin Browne (69) all had bogey-free rounds.

Fred Couples, who is in second and a shot behind Frost, was introduced as being from Newport Beach when he started at No. 1.

Couples lives in La Quinta, but said he lived in Newport Beach in the 1980s. He said he's cool with being introduced as a Newport Beach native. That's how he was introduced in 2010, when he won the Toshiba Classic.
