"I feel good," said Cruz, who is in the middle of another stint on the 15-day disabled list with a strained left hamstring. "I should be ready to go when I come off [the DL] next Tuesday."
Cruz said he was on the stationary bicycle for five minutes and then ran on the treadmill at a fast pace for five minutes as a part of his rehabilitation program. He then hit in the cage for quite a while.
This is becoming familiar territory for Cruz and the Rangers. The 31-year-old outfielder was on the disabled list three times last season due to hamstring strains, and he spent time out of action this past May because of a strained right quadriceps muscle.
The Rangers could use Cruz, and manager Ron Washington is the first to admit as much.
"We miss Nelson," Washington said on Tuesday. "He was banged up last year when we came here and he helped us out a whole bunch when he came back."
Washington said Cruz played a huge role in the team overcoming a bit of a slump last season, and he believes his return this month will be just as vital to the club making a return trip to the playoffs.
Cruz, who was in the midst of a five-game hitting streak when he suffered the latest hamstring strain while running the bases on Aug. 28, is batting .270 with 28 homers and 84 RBIs on the season. He's leading the club in homers and is second in RBIs.
The Rangers have gone 4-3 in his absence and entered Tuesday with a 2 1/2 game lead over the Angels in the American League West, which is their slimmest advantage since late August.
Last year, Texas went 7-8 from Aug. 15-29 when Cruz went on the DL for the final time. It took him a few games to get going upon his return on Aug. 30, but when he did, he stayed hot, batting .316 over his final 31 games, including .380 in a 12-game hitting streak in the September run to the playoffs.
Cruz joked about helping one of the Rangers' Minor League clubs -- four of which are in the playoffs -- win a title before returning to the Rangers.
"I'll help Triple-A [Round Rock] win a ring," Cruz said enthusiastically.
Once Cruz returns, Washington plans to use him similar to how he's inserted Adrian Beltre over the past few games.
"We may end up doing with him like I did with Beltre, where he plays the outfield one game and the DH spot another game, and then back in the outfield," Washington said.
Washington said the club will have Cruz "ramp it up" when the Rangers return to Arlington this weekend.
Cruz will still be eligible for the playoffs even if he spends time with a Minor League club.
