Manager Bob Melvin said Tuesday that "it may take some time" before Dull (knee) returns to the mound, Joe Stiglich of NBC Sports California reports.

EDGE Analysis

It appears that Dull's strained knee will continue to keep him on the shelf for the time being. Considering Melvin's comments, the A's will bring Dull along slowly before starting him back up on a throwing program. John Axford, Liam Hendriks, and Daniel Coulombe will continue to see regular work in middle relief while Dull is sidelined.

Dull underwent an MRI on Saturday, which revealed no structural damage to his knee, Jane Lee of MLB.com reports.

EDGE Analysis

While it's good news that Dull's knee isn't structurally damaged, the team didn't provide any information regarding Dull's eventual return. However, more details should become available in the near future. Before Dull landed on the disabled list, he'd pitched 15.2 innings over 18 games and compiled an ERA and WHIP of 6.32 and 1.47, respectively.

Dull (knee) is scheduled to undergo an MRI on Saturday to determine the extent of his strain, Susan Slusser of the San Francisco Chronicle reports.

EDGE Analysis

Dull said he felt a painful twinge in his knee while throwing a pitch during Friday's game, but ended up completing a scoreless inning of relief. The young right-hander dealt with hamstring and meniscus issues while pitching in college and said this pain is far worse, a disappointing sign for the Oakland bullpen. More information should become available once the examination is completed.

Dull was placed on the 10-day disabled list with a knee strain Saturday.

EDGE Analysis

Dull has had a rough month on the mound, allowing six earned runs over six innings in just seven appearances. The knee injury may have been contributing to these struggles, but now will keep the young righty sidelined for at least a week as John Axford returns to the bullpen in a corresponding move. After emerging as a dominant reliever in 2016 (2.42 ERA over 70 games), expect Dull to continue receiving chances once he gets healthy.

Dull was credited with his seventh hold of the season in Friday's 5-2 loss to the Rangers, firing a scoreless eighth inning in which he issued a walk.

EDGE Analysis

The 27-year-old right-hander now has three scoreless one-inning appearances over his last four trips to the mound, and hasn't allowed a run in five his last six outings overall. The 12 runs (seven earned) that Dull has yielded this season have been confined to four of his 15 total appearances, so he's been effective for extended stretches before the occasional implosion.

Dull (1-1) fired a scoreless 1.1 innings in Thursday's 9-6 win over the Mariners and issued a walk.

EDGE Analysis

The 27-year-old righty needed only 16 pitches to get his four outs and qualified for the win when Rajai Davis hit a go-ahead RBI groundout in the sixth. Dull extended his scoreless appearance streak to three with Thursday's outing while lowering his WHIP to 1.00. Manager Bob Melvin clearly has no qualms about giving him a heavy workload either, as he's now pitched five times over the last nine days.

Dull was credited with his third hold of the season in Tuesday's 4-2 win over the Rangers, recording a strikeout in a scoreless two-thirds of an inning.

EDGE Analysis

The 27-year-old came in with one out in the eighth and was charged with serving as a bridge to closer Santiago Casilla, a goal he met within an efficient eight pitches. Dull retired Ryan Rua on a liner to second before getting Carlos Gomez swinging, making it four straight appearances with at least one strikeout. The right-hander didn't see action between April 5 and 11, but he's now made four trips to the mound over the subsequent seven days and has thrown over 20 pitches in two of those outings.

Dull was credited with his second hold of the season in Saturday's 10-6 loss to the Astros, pitching a scoreless sixth inning while giving up a walk and recording a strikeout.

EDGE Analysis

The 27-year-old righty has a spotty track record thus far this season. Dull has given up six runs, but only three have been earned, and he's interspersed a trio of scoreless outings through his five overall appearances. He's also racked up a pair of holds and was charged with a blown save and loss against the Angels on April 4.

Dull pitched a clean seventh inning in Wednesday's 8-3 victory over the Royals and recorded a strikeout.

EDGE Analysis

The 27-year-old right-hander hadn't seen action since April 4, when he'd yielded a go-ahead three-run home run to Danny Espinosa in a 7-6 loss to the Angels. Dull has now sandwiched two perfect one-inning outings around that appearance, notching four strikeouts in the process. The young right-hander is projected to see his share of hold opportunities this season alongside fellow middle-to-late-inning options Ryan Madson, Liam Hendriks and Frankie Montas.
