Cabrera (calf) isn't starting Friday against the Mariners, T.R. Sullivan of MLB.com reports.

Cabrera tested his calf in pregame warmups, but he evidently didn't feel healthy enough to start. He may be available later in the contest off the bench.

Cooper (calf) will begin a rehab assignment with High-A Jupiter on Friday, Jordan McPherson of the Miami Herald reports.

Cooper has been out of action since late March. It's not yet clear how long his rehab assignment is expected to last.

Bour is Jeff Fletcher of The Orange County Register Friday against the Royals.

Bour is hitting jut .188/.291/.319 on the season. Mike Trout will be the designated hitter Friday, pushing Albert Pujols to first base.

Olson (hand) will take batting practice for the first time since undergoing surgery Friday, Susan Slusser of the San Francisco Chronicle reports.

This is another step in the right direction for Olson, who's expected to embark on a rehab assignment sometime during Oakland's current road trip (April 26 to May 5). He remains on track for a mid-May return, barring any major setbacks.

Guerrero is starting at third base and hitting fifth in his big-league debut Friday at home against the A's.

He slots right into the heart of Toronto's lineup, as expected. Randal Grichuk and Rowdy Tellez will hit third and fourth, respectively, while Billy McKinney and Teoscar Hernandez hit sixth and seventh. The A's are starting Mike Fiers and his 8.28 ERA, so there could be a lot of fireworks in Toronto during Guerrero's highly anticipated debut.

Guerrero's contract was selected by the Blue Jays on Friday.

The long wait is finally over. After hitting .331/.413/.531 in 288 minor-league games, the 20-year-old is poised to take over an everyday role at third base in Toronto with the potential to immediately be one of the best hitters in the big leagues. Richard Urena was optioned to Triple-A Buffalo in a corresponding move.

Walker went 2-for-4 with two doubles, an RBI and a run scored in Thursday's 5-0 win over Pittsburgh.

Walker finished up a 10-game road trip as stylishly as the Diamondbacks did. Arizona went 8-2 and swept the Pirates and Braves, while Walker batted .447 (17-for-38) with eight extra-base hits, including three home runs, and eight RBI. Off the radar when the year started, Walker ranks 10th with a 180 wRC+ through 24 games.

Calhoun went 2-for-4 with a two-run home run, two RBIs and a walk in the Angels' 11-5 win over the Yankees on Thursday.

It was a big day from atop the order for the veteran outfielder, who touched up Masahiro Tanaka with a two-run shot in the sixth inning for his sixth long ball of the year. While his power production so far is decent, Calhoun is struggling overall to start the season, as his slash line still sits at .185/.279/.424 following this performance.

Freeman went 3-for-4 with a two-run home run Thursday against the Reds.

Freeman took southpaw Zach Duke deep in the eighth inning to record his third home run of the season. He has been consistent in his production to start the season, racking up at least one RBI and run in six of his last 10 games. Through 111 plate appearances, he's hitting an impressive .326/.441/.500.

White is 0-for-10 over his first two games at Double-A Arkansas since his return from a minor-league injured list stint due to a hip flexor issue.

White's injury came at a particularly inopportune time in that he'd started the season off with a .308/.367/.385 line over his first seven games. The hope was that his stay on the shelf wouldn't cool off his bat, but for the moment, it appears that's what may have transpired. Given his prior body of work at both Low-A Everett and High-A Modesto the last two seasons, however, White would appear to have the ability to bounce back in relatively short order.
