Per Phil Miller of the Star Tribune
"The Twins signed longtime Tigers pitcher Blaine Hardy last winter in hopes he could help retire lefthanders out of the bullpen. If it happens, it won’t be in 2020.
Hardy, who owns a 3.73 ERA in 233 career games over six seasons in Detroit, underwent Tommy John surgery to replace a ligament in his pitching elbow last week, and will need at least a year of rehabilitation to recover. The surgery, performed by Twins team physician Dr. Christopher Camp last Friday, also repaired damage in Hardy’s flexor pronator, the group of muscles just above the elbow in his forearm."
