EDGE Analysis

The A's sent Frankie Montas down because they didn't need him in the rotation any longer in the first half, so naturally they summoned a fresh arm for the bullpen. Dull has a 5.06 ERA, 1.44 WHIP and 17 strikeouts in 16 innings for the A's this season.

EDGE Analysis

Dull has pitched in 17 games for the Athletics in 2018, posting a 5.06 ERA with a 17:4 K:BB over 16 innings of relief. He was cast off the active roster in order to make room for Santiago Casilla (shoulder), who was reinstated from the 10-day DL.

Dull allowed an earned run on two hits over 1.1 innings in a loss to the Diamondbacks on Friday.

EDGE Analysis

The 28-year-old right-hander had taken a liner off his glove hand Wednesday against the Mariners, but he'd stayed in the game and reports were he wouldn't miss any time. That prognosis was borne out Friday, as Dull was right back on the mound in the next possible opportunity. Dull's recent problems continued, however, as he's now allowed at least one earned run in three of his last four appearances.

Dull, who allowed a hit and recorded a strikeout over a scoreless two-thirds of an inning in Wednesday's loss to the Mariners, took a line drive off his glove hand during his outing but remained in the game, Jane Lee of MLB.com reports.

Dull was recalled from Triple-A Nashville on Saturday.

EDGE Analysis

The right-handed reliever has logged 10 innings in the big leagues (6.30 ERA) and four innings at Triple-A (2.25 ERA) so far this season. He should continue to shuttle back and forth, providing low-leverage relief depth this season. Brett Anderson was sent to the disabled list with a shoulder strain as a corresponding move.

Dull was sent down to Triple-A Nashville on Friday, Susan Slusser of the San Francisco Chronicle reports.

EDGE Analysis

Dull will be replaced by another fresh arm from the minors after appearing out of the bullpen during each of the past two days. Over 12 appearances with Oakland this season, he's struggled to a 6.30 ERA and 1.70 WHIP. Expect to see him back in the majors in the near future due to the constant revolving door that is a big-league bullpen.

Dull notched his second hold in a win over the Orioles on Friday, striking out the side in the eighth inning.

EDGE Analysis

It was another encouraging outing for Dull, who whittled his ERA down to 2.70 with Friday's dominant effort, his sixth straight scoreless appearance. The right-handed reliever figures to continue seeing his workload bump up if he's able to maintain his current caliber of performance.

Dull worked a scoreless two-thirds of an inning in a win over the Mariners on Wednesday, recording one strikeout.

EDGE Analysis

The 28-year-old right-hander has now fired 4.2 consecutive scoreless frames over his last five appearances. It's an encouraging stretch for Dull after he allowed two earned runs in his first appearance of the season back on April 17, following a late start to his 2018 campaign due to a shoulder injury.

Dull fired a scoreless sixth inning in a win over the Rangers on Monday, recording a strikeout.

EDGE Analysis

Dull was more honed in than in his 2018 debut last Tuesday, getting through his one frame on an efficient 10 pitches. The 28-year-old right-hander's season got off to a delayed start due to a shoulder injury, but his workload should start to progressively increase in the coming days and weeks.
