Hitting
Viviano never has been a patient hitter. Viviano always has been a line-drive hitter who uses the entire field. He hits righthanders and lefthanders with equal consistency.
Baserunning & Defense
He doesn't get good jumps on grounders, but his routes are fine and his hands aren't bad. His biggest problem in the field simply has to be his throwing arm... it's well below par. Viviano doesn't have great speed, though he reads righthanders' moves well enough to steal a handful of bases each season without getting caught very often.
2025 Outlook
One has to wonder what Rollie Viviano is doing in AA. In all honesty, he could use a lot of work on the fundamentals in the low minors.
