AMATEUR BASEBALL DRAFT : Marina’s Newfield Signs Contract With the Mariners

Marc Newfield of Marina High School said on Sunday that he has signed a contract with the Seattle Mariners, but refused to disclose his signing bonus.

Newfield, a 6-foot-4, 210-pound first baseman, was drafted sixth overall by the Mariners in the free agent amateur draft last Monday. Because Newfield is only 17, his parents, Richard and Dee, signed the contract with him. Players under age 18 must have parents’ signatures.

“My mom said she doesn’t want me to announce my (signing) bonus yet,” Newfield said. The sixth pick in last year’s draft, Paul Coleman of Frankston, Tex., received a $160,000 signing bonus from the Cardinals.

Newfield will report next week to the Mariners’ rookie camp in Tempe, Ariz. He said he will likely end up playing for the Mariners’ Class-A team in Bellingham, Wash. He graduates from Marina June 14.

Newfield, who bats right-handed, hit .467 this season with six homers, eight doubles and 20 runs batted in while helping Marina to the Southern Section 5-A title.

Mariners’ scout Ken Compton also announced the signing of two other local players--pitcher John Cummings and second baseman Bret Boone. Both are from USC.

Cummings, a left-handed pitcher from Canyon High School, was an eighth-round choice and will report to Bellingham. Boone, a fifth-round pick from El Dorado High School, will be assigned to Peninsula, Va., Seattle’s Class-A team in the Carolina League.
