NEW: 10-day IL with left hamstring strain. Beck was hitting .268 with 7 HRs as Colorado's everyday LF. Hamstring strains in fast-twitch outfielders typically run 3-4 weeks. Drop in 12-team formats; stash in deep leagues with the hope Coors-aided production returns by mid-June.

Multi-hit game for the Rockies' prospect. Coors inflates the numbers but Beck has real tools — speed and emerging power. NL-only and deep mixed add.
