Blalock has been on the disabled list since April 26 because of a torn left hamstring.
"He did well out there," manager Ron Washington said after putting Blalock through rigorous fielding drills. "He was moving well, making quick steps. His hands are good, his footwork is good."
Blalock said on Tuesday he hoped to be back in time for the Rangers' Interleague series against the Houston Astros beginning Friday. Washington would not say how long the third baseman might be gone.
"From what we put him through today, his hamstring is fine," Washington said. "We just want him to go and play a vigorous game for nine innings, and we'll see what happens."
