ARLINGTON -- Hank Blalock, on the disabled list with a partially torn left hamstring muscle, has resumed taking batting practice.
Blalock went into the cage on Saturday for the first time since injuring his hamstring while running the bases in a game against the Twins on April 25.
"I don't think hitting would be a problem," Blalock said. "Running is going to be the hard part. I don't think swinging the bat will be a problem from the exercises I've been doing. I feel fine there."
Blalock hasn't started full-speed around the bases yet, but has been doing strength and agility drills with strength coach Jose Vazquez.
"It felt good out there today," Blalock said. "I feel like I'm running 80 percent. Yesterday, I felt like it was 70 percent so I pushed it harder and it felt good."
The initial diagnosis was 3-4 weeks. Blalock is halfway through that, but it will likely be closer to four weeks. The Rangers still haven't determined if he'll need to go on a rehab assignment in the Minors before he's activated.
"You don't mess around with a hamstring," manager Ron Washington said. "He hasn't taken ground balls yet and he hasn't run the bases hard. Everything he has done up until now has been controlled. You test it by going out there and doing things naturally, having to stop and start quickly."
