Spring training brings promise, hope and, for the Rockies and their fans, relief. With the team preparing for the new season, the annus horribilis of 2012 Rockies baseball can be buried and forgotten.

It shouldn't be. Sifting through last year's ruins isn't an exercise in masochism. It's an opportunity to learn what went wrong, with the goal of discovering what works well. For this reason, the Rockies should be commended for refusing to treat 2012 as an aberration but, instead, as fodder for deriving hard lessons. Andrew T. Fisher covered these lessons in today's Rockpile.

One such lesson, reported last week by Troy Renck, was the new manager's mantra that Rockies pitchers must induce more groundballs. This means, apparently, working lower in the strike zone. Thomas Harding reported yesterday evening that the Rockies have employed more demanding exercises to emphasize the need to work low in the zone. The Rockies believe that last year's terror was, at least in part, "a reflection of pitches left up in the strike zone."
