Teams will be calling up players throughout the day as rosters expand to 40 spots, so keep an eye on Rotoworld’s player news page for all the latest transactions.
Along with the Brewers bringing back J.J. Hardy once his service time was sufficiently suppressed, here are some of the other noteworthy early moves:
* As expected, Jason Giambi has joined the Rockies’ bench after signing a minor-league contract last week. He went 8-for-18 with two homers in a brief stay at Triple-A and will fill the same pinch-hitting role that the Dodgers have in store for Jim Thome.
* Tim Hudson was activated from the 60-day disabled list and will make his season debut tonight against the Marlins, facing big-league hitters for the first time since undergoing Tommy John elbow surgery 12 months ago.
* Brandon Wood is back with the Angels and will no doubt take his usual seat on the bench after hitting .293/.353/.557 with 22 homers in 99 games at Triple-A. He’ll be joined by homerless wonder Reggie Willits and catcher Bobby Wilson, who reportedly might end up as the player to be named later in the Scott Kazmir trade.
* Speaking Kazmir, his old rotation spot in Tampa Bay now belongs to Andy Sonnanstine, who’s back with the Rays after a two-month demotion to Triple-A. Sonnanstine had a 6.61 ERA in 15 starts with the Rays and then posted a 4.40 ERA in nine starts at Durham, so things could get ugly tonight against the Red Sox.
* Acquired from the Orioles for a PTBNL or cash last week, Joey Gathright will be the Red Sox’s pinch-runner and defensive replacement down the stretch. Gathright isn’t much of a hitter with a career .262/.327/.303 line, but he’s one of the fastest players in baseball, has tons of range in the outfield, and will prove to be a major asset if the Red Sox ever need someone to jump over a car.
Stanton, Donaldson, Kahnle activated by Yankees ahead of Dodgers series

LOS ANGELES — Giancarlo Stanton, Josh Donaldson, and Tommy Kahnle were activated by the New York Yankees ahead of their weekend series against the Los Angeles Dodgers.
New York cleared three roster spots after a 1-0 loss at Seattle, optioning infielder-outfielders Oswaldo Cabrera and Franchy Cordero to Triple-A Scranton/Wilkes-Barre along with left-hander Matt Krook.
Stanton, Donaldson and Kahnle all played in a rehab game for Double-A Somerset. Stanton was hitless in three at-bats in his first appearance since injuring his left hamstring on April 15.
Donaldson went 1 for 4 in his fourth rehab game as he comes back from a strained right hamstring originally sustained on April 5.
Kahnle pitched one inning, giving up one run and one hit and walking two. He has been out since spring training with right biceps tendinitis.
Aaron Boone said he wasn’t concerned about Stanton returning after playing in just one rehab game. He did say that Stanton likely will be a designated hitter for a couple of weeks after rejoining the Yankees.
New York is missing centerfielder Harrison Bader, who strained his right hamstring against the Mariners and went on the injured list the next day.
Left-hander Carlos Rodón, sidelined since spring training by a sore left forearm and an ailing back, was transferred to the 60-day injured list.
