Biagini, 25, was a 26th round draft pick out of UC Davis and has been used primarily as a starter in the Giants' system for the past four seasons. With the double-A Richmond Flying Squirrels in 2015, he recorded a 2.42 ERA (3.35 FIP) in 23 games (23 starts), giving up just five home runs in 130 innings. He doesn't strike out or walk a tonne of players, having a 15.8 K% and 6.4 BB% last season, with both rates falling significantly compared to previous years in the lower minors. Biagini was chosen to be the starting pitcher for at the Eastern League All-Star Game this season.
According to MLBFarm.com, the Californian has an exaggerated overhand delivery and a "slurvy breaker" at 78-80 mph, a 87-92 mph fastball, and a 80-84 change.
As a Rule 5 draftee, Biagini must remain on the major league roster for the entire season or must be offered back to the Giants for $25,000.
I don't know if there are scouting videos of Biagini, because I stopped searching after this:
