The Giants reportedly made a move on Friday.
The five-year Major League veteran was playing for the Lancaster Barnstormers of the Atlantic League where he had a 1.63 ERA with 32 strikeouts and four walks in 26 games.
Reynolds is 5-5 in his major league career with a 3.93 ERA in 213 games (167 innings) -- all relief appearances for the Colorado Rockies and Arizona Diamondbacks.
Reynolds was traded to the D-Backs from Colorado for Ryan Wheeler in 2012 after three seasons in the Rockies bullpen. He pitched 27 1/3 innings for Arizona before an injury forced him into Tommy John surgery.
