Rockies' SS Troy Tulowtzki still has on-and-off hip discomfort.

What was initially thought to be a minor issue has snowballed into an injury that could end up costing Tulo most of the second half. He was well on his way to capturing his first MVP award, but the hip injury has all but eliminated the uber-shortstop from the running. He hasn't run since hitting the DL in late-July, so that would be the first indication of an impending comeback. ANALYST: Spencer Silva
