Stassi was optioned to Astros' minor league camp on Sunday. In 12 Grapefruit League games, Stassi hit .375 with two doubles, a home run and five RBI over 16 at-bats. The 24-year-old will open 2015 with Triple-A Fresno, where he's only a phone call away from Houston should Jason Castro or Hank Conger succumb to injury during the season.
