Denver ? Still comfortably ahead in the NL West, the Arizona Diamondbacks insisted no one was panicking despite losing for a second straight day to the Colorado Rockies.

“There’s nobody worried in here,” first baseman Mark Grace said. “We just need to go out and play better baseball.

“We’re fine. Our magic number is three. We need to go win three games, and we’ve got the ability to do it, no question. I’d like to do it the next three games.”

The Diamondbacks lost Brian Anderson to a broken foot and wasted a chance to clinch a playoff berth for the second day in a row, blowing a five-run lead in a 15-8 loss on Saturday.

Colorado, which trailed 6-1 and 8-4, tied the score with four runs in the fifth, then went ahead with a seven-run seventh that included Juan Pierre’s tiebreaking single, his fifth hit of the game.

Astros 6, Cardinals 3

St. Louis Matt Morris (16-9), struggling since he came off the disabled list, allowed all six runs and nine hits as St. Louis lost one day after clinching the NL Central.

Morris is 1-2 with a 6.14 ERA since he was activated on Sept. 10, allowing 10 earned runs in 14 2/3 innings. In his previous start, Houston chased him after 3 2/3 innings last weekend. Morris allowed five runs and nine hits in that one.

Phillies 5-5, Reds 3-4
