A's to ink highly coveted 16-year-old

Dominican hurler Inoa stands 6-foot-7, posesses 95-mph heater

ANAHEIM -- One of the worst-kept secrets in baseball will be a secret no more Wednesday morning, when the A's hold a press conference in the Dominican Republic to announce that they've signed 16-year-old right-hander Michael Inoa.

The A's brass has long been working to sign Inoa, who stands 6-foot-7, weighs 210 pounds and throws a fastball that's been clocked as high as 95 mph.

"His most attractive asset is the fact that he has a lot of control for such a tall guy, and he knows what to do once he gets on the mound," Ezequiel Sepulveda, a scout for the L.A. Dodgers in the Dominican, recently told ESPNdeportes.com. "Inoa is every scout's dream. He has it all."

Oakland general manager Billy Beane and his director of player personnel, Billy Owens, have made several scouting trips to Inoa's hometown of Puerta Plata. Beane and Owens will be featured at the press conference the A's have scheduled for Wednesday morning in Santo Domingo.

Inoa's agent, Adam Katz, on Monday told Joe Stiglich of the Contra Costa Times that the A's were the clear front-runner to land his client.

"Oakland is currently the lead dog, and we're going to make an effort to get it done with them," Katz said.

In recent weeks, speculation has mounted that the A's were going to give Inoa a $4 million signing bonus. If that proves true, it'd be the largest signing bonus in club history, topping Mark Mulder's $3.2 million in 1998.
