Give the Rockies points for creativity. They find excruciating ways to lose ballgames, largely because of their spectacular imploding bullpen. Thursday afternoon at the Oakland Coliseum, they turned a walk in the ballpark into a full-fledged soap opera. Ultimately, they lost 10-9 to the A’s in 11 innings. A few sordid details: • The Rockies led 4-0 heading into the bottom of the seventh inning before giving up 10 runs to lose the ballgame. • They scored four runs in the top of the 11th and appeared to have finally clinched the win.
