James Hoyt, 29, will join a major league team for the first time Wednesday when Houston is expected to promote the journeyman right-handed reliever.
The 2005 graduate of Boise High left baseball after lackluster college career at a Division III school and was scrubbing boats for a living. He played for three independent league clubs and in the Mexican League before catching on with an affiliated team and quickly rising through the minors.
He has a 1.62 ERA, 84 strikeouts in 50 innings and a Pacific Coast League-leading 28 saves in Triple-A this season.
Hoyt joins Josh Osich, a Bishop Kelly pitcher on the disabled list with the Giants, as Treasure Valley natives in the majors.
