RANCHO CUCAMONGA — Dodgers pitcher Casey Fien allowed one run in his lone inning of work at Single-A Rancho Cucamonga. The right-hander made his first rehab appearance Thursday, and throwing 22 pitches on the second of back-to-back nights is the big takeaway here. Fien was able to touch 93 mph with his fastball; he was sitting 94-95 prior to his elbow injury in July.

Fien was not able to hold the Visalia Rawhide scoreless. He gave up a one-out double to Joe Munoz, a right-handed hitter, on a fastball smoked into the left-center field gap. He gave up a two-out double to Victor Reyes, a left-handed hitter, on a curveball smoked into the right-center gap.

Fien was placed on the 15-day disabled list with elbow tendinitis July 17, so he’s eligible to come off any day now.

In 21 games with the Dodgers this season, Fien is 0-1 with a 4.09 ERA.

Dodgers pitcher Casey Fien will throw his first bullpen session tomorrow at Dodger Stadium since he went on the 15-day disabled list with tendonitis in his right elbow.

Fien, who has a 4.09 earned-run average in 21 appearances this season, still has no firm timetable to return to the Dodgers’ bullpen. He said his throwing program has gone smoothly since he began about four days after he went on the DL back on July 17.

“It felt like a rock in there” he said of the flexor muscle in his right forearm. “Then it just relaxed.”

Dodgers pitcher Casey Fien increased his throwing distance to roughly 100 feet on flat ground today. The right-handed reliever has been on the 15-day disabled list since July 17 with tendonitis in his right elbow.

Fien has a 4.09 earned-run average in 21 appearances out of the Dodgers’ bullpen this season.
