Rolen (shoulder) hasn't been able to swing a bat and has no timetable to resume baseball activities, the Reds' official site reports.

Spin: Todd Frazier will continue to see a heavy workload at third base, and there's certainly reason for concern given Rolen's age and injury history as he appears to be far away from returning to the Reds' lineup.

Rolen still not swinging bat

The Cincinnati Enquirer reported Monday that Reds third baseman Scott Rolen, on the 15-day disabled list, has yet to resume swinging the bat due to a strained left shoulder. He received a cortisone injection in his shoulder last week and is still in the therapy stage of his rehab. “I still have some knots and spasms,” Rolen said. “The idea was to first and foremost rest and work on it and unravel it. The fatigue and tightness build up when you’re compensating. I’m still in phase. I think Dr. (Tim) Kremchek called it active rest, which is good oxymoron. It’s more therapy stuff."

Analysis: Rolen has dealt with shoulder issues in the past and it has effected his production immensely over the last two seasons. He is batting just .224 with a .372 slugging percentage since the start of the 2011 campaign, including posting a .174 average before landing on the shelf this season. There is still no timetable for when the 37-year-old will return but owners in deeper NL-only formats should be the only ones stashing Rolen away at this point.

Impacts: Rolen was placed on the disabled list earlier this month with a strained left shoulder and has yet to resume swinging a bat. Reds manager Dusty Baker said on Saturday that he's not sure when the 37-year-old third baseman will be ready to return. With his future very much in doubt, Todd Frazier makes for a smart pickup in deeper mixed formats.
