Reds placed 3B Scott Rolen on the 15-day disabled list with a strained left shoulder. Mike Costanzo has been recalled to take his place on the active roster and may share time at third base with Todd Frazier. Rolen is off to a rough start on the season, hitting just .174 with two homers and 11 RBI in his 92 at-bats.

Scott Rolen is not in Wednesday's lineup against the Brewers. He's likely getting the day off with the early start time. Wilson Valdez will make the start at the hot corner and bat seventh against right-hander Zack Greinke.

Scott Rolen is not in Thursday's lineup. It's a day game after a night game, and Rolen traditionally gets those off. The 37-year-old third baseman is batting just .178/.241/.315 in 23 games this season. Willie Harris drew the nod at third base Thursday.

Scott Rolen homered in Thursday's loss to the Giants. Rolen was not in the starting lineup but eventually entered the game in place of Todd Frazier and hit his second home run in as many at-bats. We wouldn't count on the hot streak lasting, but it sure is nice to see the 37-year-old third baseman cranking again. His blast Thursday nearly reached the second deck at Great American Ballpark.

Scott Rolen is not in Thursday's lineup. It's a routine day off for Rolen, who hit his first home run of the season in Wednesday night's defeat of the Giants. He's still batting just .183/.246/.300 on the year. Todd Frazier is starting at third base Thursday.

Scott Rolen hit his first home run of the season in Wednesday's win over the Giants. Cincinnati's deteriorating third baseman took Barry Zito deep for a solo shot in the seventh inning, and also drew a walk. A nice night, but hardly enough to overshadow the fact that Rolen is still hitting an abysmal .183/.246/.300 through his first 64 plate appearances. He's not a viable mixed-league option, and is running out of time to prove himself in NL-only formats.

Scott Rolen is not in Thursday's lineup. The veteran third baseman is batting just .171/.209/.244 in 43 plate appearances this year, and really hasn't made great contact. It's safe to wonder whether he can make it trough the entire 2012 campaign. Todd Frazier is starting at third base Thursday against the Cardinals.

Scott Rolen is not in Saturday's lineup. Miguel Cairo replaces him at third base. The Reds plan to limit Rolen initially given his history of chronic shoulder issues. Cairo will bat fifth in the order.

Reds manager Dusty Baker plans to give Scott Rolen regular days off in hopes of keeping him healthy. It makes sense to be proactive, given Rolen's chronic shoulder issues. With Juan Francisco traded, Miguel Cairo and Willie Harris would be used at the hot corner when Rolen isn't playing. Harris has appeared in just 33 games at third in his 11-year career, but he did play there seven games last season for the Mets.

Scott Rolen doubled and scored in Monday's win over the Indians. Rolen will finish his spring hitting .356 with seven extra base hits across 45 at-bats. Healthy after shoulder woes helped limit him to a pathetic .242/.279/.397 line in 2011, Rolen is a must own in NL-only leagues. However, he might not be worth the hassle in 10-12 team mixed leagues thanks to his injury history.
