St. Louis Cardinals manager Mike Matheny wants his team to build off last year's World Series loss to Boston.
Matheny says the Cardinals can channel the disappointment they felt in that six-game defeat and use it propel them this season.
Matheny says the loss will be a "motivator" and a "very valuable tool."
St. Louis held its first full-squad workout Tuesday.
Matheny spoke to the whole team before the Cardinals took the field.
