The Cubs entered the day Friday at 10-13, and the loss Thursday dropped them 5 1/2 games behind the Cardinals.
"We've got to have a little urgency with this, too," said manager Lou Piniella, who was quick to add that he wasn't questioning the team's effort. "I'm talking about in terms of wins and losses."
The biggest problem of late has been scoring runs. The Cubs scored a total of seven runs in dropping two of three to Washington at home. On Thursday, they couldn't take advantage of the wind blowing out at Wrigley Field.
"We've got to stabilize now," Piniella said. "We're only a few games under .500. Look, we need a nice stretch. We had one here for four games, and now we're on the other side of it again."
Piniella seems to think a few hits will do the trick.
"We need to get production," he said. "I think if we can do that, everything else will settle down."
DIAMONDBACKS 13, CUBS 5: Ted Lilly gave up five runs in the fourth inning, on a three-run homer by Adam LaRoche and a two-run homer by Chris Snyder. The bullpen allowed seven runs in the seventh. The Diamondbacks out-hit the Cubs 14-6. Kosuke Fukudome hit an eighth-inning grand slam for the Cubs.
--Derrek Lee suffered through an 0-for-4 day. His batting average dropped to .193, and he is 1-for-17 on the homestand.
"My swing is just off," he said. "I'm getting my pitch, and I'm rolling over or popping up. I've got to figure out a way to get out of that."
--Aramis Ramirez had a six-game hitting streak, but it's a soft streak. He was 1-for-4 Thursday and is batting .159.
"I don't know; what can I say?" he said. "We're not hitting right now."
--Fukudome hit the first grand slam of his career, an opposite-field drive to left-center. It was the first for the Cubs this season. Fukudome is batting .328 with an on-base percentage of .419.
--Lilly was hit hard in his second start off the disabled list, allowing six runs -- and three homers -- in five innings. He's coming off shoulder surgery. He said he's fine physically and that walking batters and falling behind in counts cost him more than anything else.
"That's not my concern," he said. "My concern is winning the game. That's the only thing that's important to me right now, is getting the job done."
--Ryan Theriot has a nine-game hitting streak during which he's gone 21-for-43 (.488). Theriot is batting .340 with a .375 on-base percentage.
"Everybody does things differently to get back on (track), and the reason that is is because nobody has the same swing," he said. "Everybody is doing something different."
