Tonkin (shoulder) hopes to be cleared to return after throwing from flat ground Saturday, Mike Berardino of the St. Paul Pioneer Press reports.
He threw a 20-pitch bullpen session Friday, throwing all of his pitches, and will throw from flat ground again Saturday in hope of getting cleared by the medical staff. His 25.5 percent K-rate is solid enough, but his 4.30 ERA and 1.41 WHIP leave a lot to be desired.
