The Pirates placed outfielder Nate McLouth on the 15-day disabled list yesterday because of a sprained left ankle, but it could be a good bit beyond two weeks before he returns.
A magnetic resonance imaging scan detected no fractures, but there is "fairly significant" damage to ligaments near the lower back portion of the foot, McLouth said, and no firm timetable has been established for a full recovery.
Manager Jim Tracy described McLouth's status beyond his stint on the disabled list as unknown, and McLouth had no further information.
"We're hoping it's not more than a couple of weeks," McLouth said.
McLouth was injured Friday when running toward third base for a stand-up triple. As he was about 10 feet away from the bag, he felt the tweak in the ankle, which he said had no previous trouble.
"All I did was put on the brakes to go in there nice and easy, and it went."
To replace McLouth, the Pirates promoted center fielder Rajai Davis from Class AAA Indianapolis.
For Davis, 25, it was his first summons to Major League Baseball after nearly six full seasons in the team's minor-league system, and his pride was easy to detect upon his entering the clubhouse.
"It's definitely my biggest dream come true," Davis said. "I'm very grateful."
In 100 games with Indianapolis, Davis batted .283 with two home runs, 21 RBIs and 45 steals in 58 tries. He also had a .335 on-base percentage that is considered low for a leadoff man, largely the result of drawing only 27 walks.
He said reaching base has been an area of focus this year.
"I always thought about it, but this season I felt like I could actually do it. I didn't have the knowledge before."
Tracy indicated Davis would be used in a reserve role.
Doumit back in action
Catcher Ryan Doumit, out since June 4 because of a torn left hamstring, played in his first rehabilitation game yesterday for Bradenton of the Gulf Coast League: He flied out twice and walked in three plate appearances, then was removed after six innings.
The Pirates' plan is to have him play there about a week, then move up to a higher minor-league team.
The Philadelphia Phillies have made known their interest in acquiring a third baseman, and the Pirates continue to offer Joe Randa, who might be the most attractive option available. Until Aug. 31, players can be traded, provided they clear waivers, which Randa probably has.
In John Van Benschoten's first rehabilitation start with Class AA Altoona last night, he allowed two runs and three hits in five innings. He struck out three, walked three and threw a wild pitch. His next stop could be Indianapolis.
The Pirates opened the season with one African-American -- starter Ian Snell -- on the 25-man roster. Davis' addition, along with the July 31 trade for starter Shawn Chacon, has raised that to three. Only eight other teams have that many.
Davis was a member of the 40-man roster, so that list remained at 37.
INDIANAPOLIS (66-56) won at Charlotte, 5-3. LHP Sean Burnett (8-9, 4.76) allowed one run and five hits in 5 1/3 innings. He struck out two, walked five and threw 45 of 84 pitches for strikes. RHP Jesse Chavez (5.40) pitched 1 1/3 scoreless innings of relief. RHP Jonah Bayliss (1.70) pitched a scoreless ninth for his 20th save. C Carlos Maldonado (.299) went 2 for 4 with his sixth home run and two RBIs.
ALTOONA (67-51) swept a doubleheader at Connecticut, 4-2 and 6-3. In the first game, RHP John Van Benschoten (1-0, 3.60) allowed two runs and three hits in five innings. He struck out three and walked three. In the nightcap, RHP Nerio Rodriguez (0-0, 4.50) allowed two runs in four innings. For the day, CF Nyjer Morgan (.296) went 4 for 6 with a walk, two steals and two runs.
LYNCHBURG (50-68) lost to Myrtle Beach, 10-8. RHP Derek Hankins (3-10, 4.46) allowed three runs in 4 1/3 innings. C Neil Walker (.284) went 4 for 5 with a double and two RBIs. 1B Steve Pearce (.257) went 2 for 3 with his 11th home run, a walk and two RBIs.
