Cassy Isagawa’s preference for a neon yellow golf ball predates her career at Oregon. It just happens to blend well with her current color scheme.

The Baldwin grad started playing a yellow ball while racking up junior golf accolades and a high school state championship and stuck with it when she joined the Ducks golf team.

Following a successful junior season in Eugene, Isagawa directed the distinctive Srixon around Oahu Country Club efficiently over the past two days in her Manoa Cup debut.

Isagawa qualified for the state amateur match play championship on Monday and advanced in the 64-player bracket with a 5-and-3 victory over Dennis Harrison in the first round on Tuesday.

"I always wanted to play Manoa Cup just because it’s a great experience," Isagawa said. "I heard from (past Manoa Cup participants and current college golfers) Alina Ching and Marisa Chow that this is a great event. … I’m really glad I came. It’s just the environment here. I see a lot of my friends here and it’s fun."

Isagawa will face Scotty Yamashita, a 3-and-1 winner over Shon Katahira, in Wednesday’s 8:24 a.m. pairing in the second round of the 106th Manoa Cup.

Isagawa returned to Hawaii after posting a 72.95 scoring average, the third best in program history, and earning second-team All-Pac-12 honors. She won the Dick McGuire Invitational in New Mexico in the fall, ended the season ranked 37th nationally and qualified for the NCAA West regional.

"I played really steady this year," Isagawa said. "I didn’t play as strong as I wanted to toward the end, but I had a very consistent season."

She’s maintained her solid play so far this week while shooting a 1-over-par 72 on Monday and protecting an early lead Tuesday.

"I putted really well today," Isagawa said. "I didn’t make a ton of putts, but I rolled a lot of good putts at good speeds."

Isagawa was one of three women to qualify, with two advancing to the second round. Alice Kim, a University High product now playing at Gonzaga, edged Dalen Yamauchi 2 up. Monique Ishikawa lost to 2012 Manoa Cup champion Matthew Ma 3 and 1.

Jun Ho Won and Brent Grant, teammates at Moanalua this past season, were among the first to finish their matches on Tuesday.

Won, an incoming sophomore for Na Menehune, scuffled to a 79 on Monday and squeezed into the bracket as the 64th seed. But the seedings matter little once the matches start, evidenced by his 4-and-3 win over top-seeded Jared Lydon.

Won, who moved to Hawaii from South Korea last August, started the day with a triple bogey on his first hole Tuesday, but steadied himself to win the next three holes.

"Since it’s match play, triple doesn’t matter. I just lost one hole," Won said.

Grant shared medalist honors with Lydon and Tyler Munetake with a 66 on Monday and stayed hot in an 8-and-7 win over Pono Tokioka.

Grant had the morning’s first tee time off No. 10 and promptly stuck his drive on the green to set up his first birdie of the day. Other than that, Grant said his round was, "nothing too spectacular, just nice and steady."

The youngest player in the field, 12-year-old Taylor John McGerity, ended his stay with a 5-and-4 loss to Scott Ichimura.
