The Cartwright Cup, emblematic of the state high school baseball championship, will be unveiled at 10 a.m. on Sunday at the Honolulu Stadium Park on King Street.

The 3-foot-high koa and brass trophy, named in honor of the founder of the sport Alexander Joy Cartwright Jr., will be presented to the 2007 winner of the Wally Yonamine Hawai'i State High School Tournament on May 12 at Les Murakami Stadium.

Past winners of the tournament since 1959 will be engraved on the four-sided trophy with the new winner added each year.

The perpetual trophy will be permanently housed at the University Branch of First Hawaiian Bank at South King and Isenberg streets with the winning school receiving a smaller version of the award.

A trophy cup, etched with "The Cartwright Cup" and the baseball logo from the plaque at Cartwright's gravesite at O'ahu Cemetery, will sit above the koa base. Brass plates listing the champions will be directly below the cup.

Keith Amemiya, Executive Director of the Hawai'i High School Athletic Association, and Friends of Alexander Joy Cartwright Jr. will gather near the home plate area of the original Honolulu Stadium for the unveiling.

Long-time sportscaster Don Robbs will serve as MC.

Cartwright, who is in baseball's Hall of Fame, invented the game in New York in 1845 and wrote the first rules that are still used today: nine men to a side, 90-feet between bases, three outs per inning and the setting of the foul lines.

In addition to his connection with the sport, Cartwright played an integral part in the growth of Honolulu.

He was a counsel to the king and also played a major role in the founding of The Queen's Medical Center, the state library system and the Honolulu Fire Department.

The trophy was designed by Patrick J. "Korky" Gallagher and created by Rowland Fujii of KF Enterprises.
