Mark Teixeira never thought his sore left wrist would be a serious problem. When he missed just two games after aggravating the injury at the end of July, it seemed he was right.

But the Yankees first baseman sat out again last night and missed the Yankees' 6-4 victory over the Red Sox, and manager Joe Girardi acknowledged the issue could linger.

"I don't think it's a long-term problem, but we have to get through this," said Girardi, who provided no assurances Teixeira would be back today. "I wouldn't be surprised if it was more than a day.''

Teixeira could not pinpoint what made the soreness reappear, attributing it mostly to simple wear and tear.

"It's been sore the last few days, so we'll give it a day or two to calm down," Teixeira said. "We haven't had any days off since the [cortisone] shot when I had those two days. … It was probably time to give it a little rest anyway and it being little sore, it just makes sense. We'll see how it goes."

With Alex Rodriguez already nursing a fractured left hand and starting pitchers CC Sabathia and Andy Pettitte also on the disabled list, the first-place Yankees would like to avoid any further serious injuries. So they figure to be cautious with Teixeira.

Despite the recurrence of inflammation, he said he hopes he won't have to deal with the injury for the remainder of the year.
