NEW YORK -- Weather and scheduling delivered a hit to Hank Blalock's hitting plans for the weekend.

Blalock was hoping to take some outdoor batting practice on Saturday to test his right wrist, but the storm that passed through New York scratched that plan. Both batting practice and Saturday's game were postponed.

The game was rescheduled for Sunday as part of a doubleheader, but for the second straight day, there was no on-field batting practice. So Blalock is still uncertain when he'll be able to go on a medical rehabilitation assignment, which is the usual precursor to being activated off the disabled list.

"I just haven't planned it out," said Blalock, who has been on the disabled list since April 29.

Blalock and the Rangers still hope he can be activated off the disabled list on Friday when they open a three-game series against the Nationals in Washington D.C. But they still want him to play at least three games on medical rehabilitation assignment in the Minors before that happens.

"We just want to make sure everything is healed," manager Ron Washington said. "I'm not concerned about his hitting. He just needs to see some pitching and get some live work around first base."

Blalock had surgery on his wrist on May 30, leaving his right hand weak. He was hoping that a couple of days of intensive outdoor batting practice would strengthen and test it while the Rangers were at Shea Stadium. That did not happen, so Blalock will try again on Monday when the Rangers return to Arlington. He'll take batting practice on Monday at Rangers Ballpark, then see what the next step is.

"I'm just taking each day as it comes," Blalock said.
