"I told myself if I got drafted I was going to sign no matter what," Boyd said.
Boyd arrived at the A's spring training facilities at Papago Park in Phoenix on Wednesday, where he will work out under the direction of A's Director of Player Development Keith Lieppman.
"He's my next call," Boyd said. "I just got here and I'm ready to go."
Boyd hasn't been told where he will be playing this summer, though it's likely he may stay in Arizona. He's one of 21 A's draft picks (of 43) who have signed, and is the only high school player to have signed.
The A's used five of their first seven picks to draft a high school player. Boyd is one of eight of the top 18 picks who have agreed to terms. Birmingham Southern catcher Bruce Maxwell, taken in the second round, is the highest draft pick to sign.
Menlo School juniors Michaela Michael and Ali Kim have been named to the Girls High School All-American first team by the Northern California chapter of US Lacrosse.

Michael finished ranked No. 3 in the nation in goals scored (131) and No. 1 in the state, according to Maxpreps.com. In points (goals and assists), Michael ranked No. 6 in the nation and No. 1 in California with 162.
Receiving honorable mention All-American recognition were Palo Alto High senior Kimberley Flather, Paly junior Nina Kelty and Sacred Heart Prep sophomore Caroline Cummings.
Honorees were nominated by their respective coaches, and selected by a committee of coaches and officials representing the various leagues and sections in the Northern California Chapter.
Selections were submitted for final approval to US Lacrosse, which defines an All-American as one who exhibits superior skills and techniques as well as exceptional game sense and knowledge, while embodying good sportsmanship.
"These players represent not only the very best of Northern California, but players who stand alongside the very best high school girls lacrosse players in the nation," wrote Ken Cuozzo, the US Lacrosse Girls High School All-American chairman.
