Dull, just activated from the 10-day disabled list last Saturday, allowed a two-run home run and a wild pitch while also recording four strikeouts over an inning in a 10-2 win over the White Sox on Tuesday.

EDGE Analysis

His season-opening jitters actually enabled him to put together quite the unique stat line over his one frame. Dull rang up Omar Narvaez, the first batter he'd faced this season, on a swinging strike three that got past Jonathan Lucroy, allowing Narvaez to reach first. Yoan Moncada then made Dull pay with a 387-foot shot to right that did away with the Athletics' shutout bid. However, the 28-year-old right-hander responded in impressive fashion, recording three more whiffs by mowing down Chad Pinder, Khris Davis and Matt Olson, the last two on swinging strikes. Now apparently at full health after his shoulder issues, Dull should be in for a relatively brisk workload as the season unfolds.

Dull (shoulder) was activated from the 10-day disabled list Saturday, Julian McWilliams of The Athletic Bay Area reports.

EDGE Analysis

He switches places with Liam Hendricks, who landed on the DL with a right groin strain in a corresponding move. Dull should work in low-to-mid leverage innings going forward. He gave up one run while striking out three in four rehab innings at Triple-A Nashville.

Dull (shoulder) is expected to be activated before Saturday's game versus the Mariners, Jane Lee of MLB.com reports.

EDGE Analysis

The 28-year-old has put in three rehab appearances at Triple-A Nashville after missing all of spring training, allowing an earned run on four hits and a walk across four innings while recording three strikeouts. Dull was already at Safeco Field with the team on Friday, with manager Bob Melvin noting that the right-hander is "fully healthy now" and ready to make his season debut.

Dull (shoulder) pitched two innings on a rehab assignment at Triple-A Nashville on Friday, Susan Slusser of the San Francisco Chronicle reports.

EDGE Analysis

Dull missed spring training with a sore shoulder and started the season on the 10-day disabled list. The 28-year-old's lack of work this spring likely means he'll need at least a handful of appearances with Nashville before returning to the Athletics, where he is expected to serve as a low-leverage reliever.

The Athletics officially placed Dull on the 10-day disabled list Wednesday.

EDGE Analysis

Dull's sore right shoulder prevented him from pitching in any Cactus League games after Feb. 23, so he'll presumably stick around at the Athletics' complex in Arizona in order to get some additional reps in against live hitters. It's expected that Dull will settle for lower-leverage work with the big club upon returning from the DL.

Dull (shoulder) is scheduled to pitch an inning in a minor-league game Thursday, Susan Slusser of the San Francisco Chronicle reports.

EDGE Analysis

It seems unlikely that Dull will make an appearance in Cactus League play this year, but it's still a good sign that he can appear in game action at all. No firm timetable for his return has been established yet. He should return to the back of Oakland's bullpen as soon as this issue is behind him.

Dull (shoulder) will begin the season on the disabled list, Julian McWilliams of The Athletic Bay Area reports.

EDGE Analysis

This was to be expected, as Dull hasn't been able to see any Cactus League action to this point. He'll likely be put on the 10-day disabled list to start the regular season and eventually placed near the back of the A's bullpen when healthy.

Dull (shoulder) is scheduled to face hitters Monday in live batting practice or a simulated game, Susan Slusser of the San Francisco Chronicle reports.

EDGE Analysis

With Opening Day less than two weeks away and Dull having failed to pitch in a Cactus League game since making his spring debut Feb. 23, it seems likely that he'll open the campaign on the 10-day disabled list. After tallying a 5.14 ERA and 1.26 WHIP in 42 innings with the Athletics a season ago, Dull won't be guaranteed a high-leverage role in the Oakland bullpen once his shoulder soreness has subsided.

Dull (shoulder) threw a bullpen session Tuesday, Susan Slusser of the San Francisco Chronicle reports.

EDGE Analysis

Dull hasn't thrown a bullpen session since being shut down with shoulder discomfort in late February. He's fighting for a spot in Oakland's bullpen, though at this point it may be tough for him to get enough innings this spring in order to claim a spot.

Dull (shoulder) will play catch Sunday, Susan Slusser of the San Francisco Chronicle reports.

EDGE Analysis

Dull is working his way back from shoulder soreness after being temporarily shut down in late February. He is battling for a spot in Oakland's bullpen, but he'll need to throw a decent number of innings this spring to stake his claim.
