The Royals outrighted Black to Triple-A Omaha on Thursday.
The transaction frees a spot on the 40-man roster as the Royals head into the offseeason. Black has made eight starts and 19 relief appearances thus far at the big-league level, logging a 5.53 ERA, 1.62 WHIP and 55:35 K:BB over 71.2 innings. He'll turn 27 in December.

The Royals optioned Black to Triple-A Omaha on Thursday.
Black pitched two scoreless innings during Wednesday's contest, marking the first time since June 7 that he didn't give up a run during an appearance in the big leagues. Now carrying a 4.31 ERA and 1.60 WHIP on the season, he'll move back down to Triple-A so the Royals can bring in a fresh arm in the form of Anthony Gose.

Black struck out a batter and allowed two earned runs on two hits and three walks in Tuesday's 4-3 win over the Athletics.
For a third consecutive appearance since being called up from Triple-A Omaha on Aug. 7, Black ended up covering multiple innings in relief behind starter Daniel Lynch. The two pitchers' schedules have been intertwined while Lynch has gradually been building up his pitch count after making the in-season transition from relieving to starting, but Black could soon be ready to handle a more flexible relief role. Lynch tossed four innings and 45 pitches Tuesday and could be ready to handle five or six innings when his turn in the rotation comes up again Sunday versus the Tigers.

Black struck out a batter and allowed one earned run on three hits and two walks across three innings of relief in Wednesday's 4-2 loss to the Dodgers.
For the second time since he was recalled from Triple-A Omaha last Friday, Black pitched in long relief behind starter Daniel Lynch, who is getting gradually stretched out as he transitions from the bullpen to the rotation. After tossing five innings Friday against the Cubs, Black wasn't needed to provide as much length Wednesday, with Lynch building up to 2.1 innings and 39 pitches. Unless he's incredibly economical with his pitch count in his next projected start Tuesday versus the Athletics, Lynch is unlikely to reach five innings, so Black could have decent odds of picking up a win in that game if he's available to pitch behind Lynch.

The Royals recalled Black from Triple-A Omaha on Friday.
Black will take the 26-man roster spot of Aaron Bummer, who has elected free agency in lieu of heading to Triple-A. Black has pitched in 12 games out of the bullpen for Kansas City this season, posting a 3.57 ERA, 1.70 WHIP and 15:11 K:BB across 17.2 frames.

The Royals optioned Black to Triple-A Omaha on Friday.
The right-hander was called up by the Royals in late May and will return to Omaha after giving up seven runs with a 10:9 K:BB over 13 innings during this stint in the majors. Black's demotion clears roster space for Seth Lugo (concussion), who is starting Friday's game against the Cardinals.
