Bobby Crosby hopes his second comeback of the season is as successful as his first.

The Athletics activated the reigning AL rookie of the year from the 15-day disabled list yesterday and rewrote the lineup with him at shortstop and batting seventh for the opener of a three-game series against the Twins.

Crosby, recovering from a fractured left ankle that forced him into a second stint on the DL this year, fielded ground balls, ran the bases and took batting practice in the cage before the Athletics decided he was ready to go -- or as ready as he's going to be for the stretch run.

"My feeling is why not get him back in there, kind of like last time," Manager Ken Macha said. "The sooner we get him back on the field and get him some at-bats, the sooner he'll get going."

Crosby already sat out April 5 to May 29 with two broken ribs after getting hurt on Opening Day at Baltimore. The Athletics went 55-24 for a .696 winning percentage from the day he came back (May 30) to Aug. 27, when he got hurt again -- also in Baltimore. He collided with Orioles C Sal Fasano.

"I feel it," he said. "There's still a broken bone in there. . . . Hopefully, I can come out hot like last time I came off an injury. Last time it worked out well. Hopefully, we can do the same thing."

In addition, RHP Rich Harden, who began the season as the number two starter behind Barry Zito, threw long toss in the outfield as he works to recover from a strained muscle in the back of his throwing shoulder that has sidelined him since Aug. 19.

"I wish the news would be better on that front, but it's not," Macha said.

* HANSEN DEBUTS: The Red Sox called up reliever Craig Hansen, the team's first-round draft pick, from Class AA Portland, and he made his major league debut hours later against the Devil Rays.

The right-hander entered in the fifth with Boston trailing 5-4 and retired all three batters he faced, striking out two.

The Red Sox also recalled IF Hanley Ramirez from Portland. In his first full Class AA season, Ramirez hit .271 with six homers and 52 RBI. He could see action mainly as a pinch runner.
