From BA: 

Armas is a 6-foot, 185-pound catcher who stands out for his catch-and-throw skills behind the plate. He’s a hyper-mobile athlete with impressive actions behind the dish and a chance to be an above-average defender. This spring with San Diego Armas threw out 15-of-32 (46.9%) basestealers. His offensive game is a bit lighter and he’s a career .266/.372/.390 hitter over three seasons with just nine total home runs, but scouts do think he has solid pure contact skills.
