Rockies starter Ubaldo Jimenez improved to 15-1 with a 2.20 ERA after Thursday's victory against the Cardinals.

Jimenez is the first pitcher to record 15 wins by the All-Star break since David Wells accomplished the feat in 2000.

He has won 32 percent of Colorado's games and they are 16-2 in his starts.
