National League Notes: Phillies, Boras, Weiss

The Phillies have been a playoff contender for the better part of the past half decade, but time and a decline in talent may mean the window of opportunity is quickly closing at Citizens Bank Park, writes Ryan Lawrence of the Philadelphia Daily News. "A lot of it will depend on how people perform, on how the young players perform," Amaro said. "At some point we're going to be filtering some young players onto this club and we need to find out who needs to be those guys to keep us going, to keep us afloat." Here's the latest news from around the National League.

• Scott Boras believes the market is heating up for his unsigned clients like Kyle Lohse and Jose Valverde thanks to the start of Spring Training, says Adam Berry of MLB.com. "Like most free agents with that kind of ability, I think you get all kinds of calls. Frankly the calls increase during Spring Training rather than decrease because the need level of each club is more evident," Boras said. "These are ownership decisions at this point. The talent is there. 
• Walt Weiss must put his stamp on every aspect of his squad as he enters the 2013 season as the Rockies first-year manager, writes Troy E. Renck of The Denver Post. Renck points to Todd Helton as the starting point with his declining skills, inability to play a full season and the lingering DUI arrest that must be addressed by the veteran first baseman in front of the team. 
• John Mozeliak's contract extension from the Cardinals stems from his linear integration model that has paid dividends in the form of victories at the Major League level, says Derrick Goold of the St. Louis Post-Dispatch. “I think he’s got a real sense of how to make a decision and a recommendation and not panicking into doing something that is good for the moment,” Chairman Bill DeWitt Jr. said.
