NL Notes: Chapman, Stewart, Rockies, Braves

St. Patrick's Day is as much of a baseball holiday as Memorial Day, the Fourth of July, or Labor Day thanks to former Reds GM Dick Wagner. Tom Singer of MLB.com chronicles how the baseball tradition of wearing the green came about 35 years ago. Elsewhere from the Reds and the rest of the National League:

• Reds GM Walt Jocketty expects a decision in the next few days on whether Aroldis Chapman will pitch out of the bullpen or be moved into the starting rotatation, reports MLB.com's Mark Sheldon. Chapman stated publicly he wants to close, which didn't sit well with Jocketty. "We don’t let every player tell us how they want to be used," the GM told MLB.com.
• Ian Stewart's lingering left quad injury could affect his chances at making the roster and how the Cubs build their bench, writes MLB.com's Carrie Muskat. Brent Lillibridge, Luis Valbuena, Edwin Maysonet, and Alberto Gonzalez are competing to fill that void while manager Dale Sveum mentioned Steve Clevenger could be an interesting option and added the team is watching all the waiver wires. 
• The Rockies are giving serious consideration to making Nolan Arenado their starting third baseman with one club official telling Ken Rosenthal of FOXSports.com "it’s a tough call." If Arenado receives the nod, Rosenthal believes incumbent third baseman Chris Nelson could be used to acquire a veteran starting pitcher.
• Within the same piece, sources tell Rosenthal the Rockies want to move Ramon Hernandez and are willing to assume some of his $3.2MM salary to facilitate a trade.
• Don't expect the Braves to have any interest in the recently released Matt Diaz because there isn't a need right now, tweets David O'Brien of the Atlanta Journal-Constitution.
• The Marlins have returned Rule 5 selection Braulio Lara to the Rays, reports Joe Capozzi of The Palm Beach Post. The left-hander appeared in four games for the Marlins this spring throwing four innings allowing two earned runs on five hits with two strikeouts and two walks.
