Harden, who is on the 60-day disabled list, has been sidelined with lat muscle soreness under his throwing arm and has yet to pitch this season. But the hurler, who signed a one-year deal worth $1.5 million as a free agent in the offseason, tossed two side sessions in the past week on Saturday and Tuesday.
Although the throwing sessions are a positive step for Harden, A's manager Bob Geren said the righty is still a long ways away from throwing simulated games. In the meantime, Geren said he is just looking to make sure Harden feels good during the throwing sessions and is "free and easy."
"[Tuesday] was better than his first one, which was encouraging," Geren said. "He's just continuing to follow that plan, from long toss, to on the mound and build up from there."
Harden will travel with the team when it embarks on a 10-game road trip, and Geren said the plan is for Harden to throw another session on Friday in Boston.
