Injuries: Neftali Feliz throws off flat ground

SURPRISE, Ariz. -- Neftali Feliz is continuing his rehab from Tommy John surgery in Arizona and is throwing off flat ground from 60 feet. He'll continue to build up, but it's a slow progression after undergoing August surgery. There's no set timetable for his return, but it would probably be late in the season.

Some other injury news:

* Colby Lewis (flexor tendon surgery last July) is throwing at 120 feet. Read more about that here.

* Roman Mendez (stress fracture repair in right elbow in November) is throwing out to 120 feet.

* Justin Miller (Tommy John in April) is scheduled to throw his first rehab bullpen today.

* Matt West (Tommy John in August) is throwing to 60 feet.

* Kyle McClellan (shoulder surgery in July) and Randy Wells (elbow scope in July) are on normal schedules.
