Mikolas (forearm) allowed an earned run on four hits and a walk over 4.2 innings in Double-A Springfield's win over Tulsa on Tuesday. He struck out three.
The right-hander bumped his pitch count up to 67 in what was his third straight encouraging rehab start. Assuming Mikolas' previously ailing forearm tolerates the increase in activity level well over the next several days, the veteran's next start could come with the big-league club this weekend.
