YAKIMA, Wash. — It’s hard keeping up with the Gomezes, Gloria and Julio, that is.

That’s because their son, Gabriel Gomez, the Eisenhower High School graduate who until a few weeks ago was seen as an also-ran in the Massachusetts Senate race, pulled off an upset victory in the Republican primary Tuesday.

Gomez, 47, a Cohasset businessman and former Navy SEAL, defeated former U.S. Attorney Michael Sullivan and state Rep. Daniel Winslow in the Republican primary, according to unofficial returns. He will face Democratic U.S. Rep. Edward Markey in the special election scheduled for June 25.

On Wednesday, Gomez’s parents, who still reside in the Yakima area, were ecstatic over his victory.

“It’s going to be an uphill battle, but we are really optimistic about it,” Julio said in a telephone interview.

Gloria said watching returns Tuesday night was an up-and-down experience emotionally until a winner was finally declared.

“I knew he was ahead but you never know until the end,” she said. “It was amazing.”

Julio, a former sales executive with the local hops producer S.S. Steiner, said friends from as far away as Colombia and France have been calling the family to congratulate them on the primary victory. Both Gloria and Julio are natives of Colombia.

“We are really excited,” Julio said.
