A couple of weeks ago, it showed up in the transaction logs that the Giants had signed first baseman Ronald Guzmán to a minor league deal. The club today announced to reporters, including Grant Brisbee of The Athletic, a batch of players that would be in camp as non-roster invitees. Among them was Guzmán, though he was listed as both a pitcher and an infielder. Video of Guzmán pitching recently appeared on social media, with the Instagram account Dominican Baseball Solutions sharing some footage back in December.
The fact that the Giants are announcing Guzmán as a pitcher suggests that they are at least somewhat willing to give him a real shot to prove himself in that capacity. He doesn’t yet have any professional experience as a pitcher, though the Instagram post linked above says that he was hitting 96 mph on his fastball, as well as throwing a slider at 82 mph and a changeup at 84.
