After clearing waivers, the former SF Giants prospect had a chance to stick with the Astros but has chosen free agency instead.
Since the right-handed reliever had over three years of service time, he had the option to elect for free agency after being removed from the 40-man roster. This seemed likely as it would allow Biagini to pursue opportunities outside of the Astros organization.
The Giants originally drafted Biagini out of UC Davis in the 26th round of the 2011 draft. I should add that the fact that a 26th rounder made it to the majors is an impressive accomplishment in and of itself.
