Decker is playing center field and leading off Tuesday against the Rangers, Jane Lee of MLB.com reports.

EDGE Analysis

Decker earned himself an opportunity to lead off after going 3-for-4 with an RBI and a stolen base in his first game after being called-up. It's only one game, but if the 27-year-old is able to keep producing at the plate he could continue to steal some at-bats away from the struggling Rajai Davis.

Decker went 3-for-4 with an RBI single, triple, run and stolen base in Saturday's 10-6 loss to the Astros.

EDGE Analysis

Called up from Triple-A Nashville earlier in the day to replace the struggling Mark Canha, Decker did some damage out of the eight-hole, an extension of the impressive season he's put together thus far for the Sounds. The 27-year-old has slashed .387/.472/.452 in 31 at-bats in the minors, and Saturday's splashy debut certainly provides reason for optimism. Decker was also impressive while with the A's this spring, but his career .183 average over 133 plate appearances at the major-league level offers some sobering perspective for the time being.

Decker's contract was selected by the A's on Saturday.

EDGE Analysis

The 27-year-old Decker will take the roster spot of Mark Canha, who was optioned in a corresponding move after a tough start to the year. Decker, on the other hand, has been on a tear at Triple-A Nashville, slashing .387/.472/.452 over 31 at-bats. He figures to slot into a bench role and could see the occasional start in the outfield.

Decker was reassigned to minor league camp Saturday, Joe Stiglich of NBC Sports Bay Area reports.

EDGE Analysis

Mark Canha will serve as the A's lone extra outfielder with Oakland opting to keep an eight-man bullpen to start the season. With that, Decker was the last position player sent down prior to Opening Day. Decker slashed an impressive .313/.421/.500 this spring and manager Bob Melvin said that sending him down was "the hardest one" of the final roster cuts.

Decker (oblique) is scheduled to rejoin the Athletics for Monday's Cactus League game against the Royals, Susan Slusser of the San Francisco Chronicle reports.

EDGE Analysis

Decker seems to be in the clear from the oblique injury, as he was cleared to play five innings in center field in a minor-league game Sunday. Assuming he comes out of that appearance OK, he'll be available Monday for the A's, though he may not be included in the lineup. The 27-year-old is competing for a reserve gig in the outfield with the big club.

Decker says his oblique injury has subsided and he will play in a minor league game Sunday, Susan Slusser of the San Francisco Chronicle reports.

EDGE Analysis

It's great news for Decker, who is battling Alejandro De Aza for a reserve outfield role on the Oakland roster. The lefty has put together a solid spring thus far, slashing .304/.407/.478 through 16 Cactus League games. Look for him to return to regular action within the coming week.

Decker (oblique) took 60 swings in the batting cage Thursday, Susan Slusser of the San Francisco Chronicle reports. He hopes to participate in batting practice Friday and suit up for a minor league game Saturday.

EDGE Analysis

Decker is ramping up his activity in his quest to break camp with Oakland. The former prospect had been hitting well this spring (.304/.407/.478 in 23 at-bats) before this setback.

Decker (oblique) will participate in on-field baseball activities except batting practice Thursday, though he's hit off a tee, Joe Stiglich of CSN California reports.

EDGE Analysis

The once hyped prospect is making progress in rehabbing his injury and has handled the bat well this spring, owning a .304/.407/.478 line that includes four doubles, two RBI, four walks and four runs over 23 at-bats. If he can return to action and sustain that performance, Decker should lock down a roster spot when the A's break camp.

Decker (oblique) was examined by a doctor Monday and could start taking swings again Tuesday, Joe Stiglich of CSN Bay Area reports.

EDGE Analysis

The 27-year-old outfielder is attempting to secure a roster spot and is therefore highly motivated to jump back into action as soon as possible. Decker originally suffered the injury while taking swings in the batting cage on Saturday but could be back to handling a bat Tuesday if he's deemed ready to do so. He's slashing .304/.407/.478 with four doubles, two RBI, four walks and four runs over 23 at-bats this spring.

Decker said he is dealing with a minor oblique injury, and that he was able run and throw without a hitch on Monday, Susan Slusser of the San Francisco Chronicle reports.

EDGE Analysis

Decker joined the A's camp as a non-roster invitee looking to claim a major league roster spot as the team's fifth outfielder, something that is within reach with Jake Smolinski sidelined for the start of the season. It's unclear how much longer the minor oblique injury will sideline him, but the 27-year-old could be in jeopardy of missing the Opening Day cut if he isn't able to return to the field shortly.
