Rosario was optioned to Triple-A Iowa on Friday.
The southpaw returns to the Triple-A level after Carl Edwards Jr. was activated from the 10-day injured list. In Rosario's 3.2 major-league innings since being called up in early July, he gave up two runs off four hits while recording only one strikeout. The 25-year-old could be a candidate to return to the majors should injuries occur in the Cubs' bullpen, but his stock within the organization could fall if the team adds bullpen arms as the trade deadline approaches at the end of July.
Rosario (1-0) retired the lone batter he faced and earned the win in Friday's game against the Pirates.
Fellow reliever Pedro Strop allowed a game-tying, three-run homer in the eighth inning before getting the hook with two outs. Rosario retired All-Star slugger Josh Bell on a groundout and picked up win No. 1 when the Cubs scored a run in the bottom of the frame. Rosario has mostly toiled in Triple-A this season and has just nine innings at the MLB level, though he did toss 46.2 innings and register a 3.66 ERA for the Cubs in 2018, so he could stick around in the second half of the year as a lefty specialist.
Rosario was recalled from Triple-A Iowa on Tuesday, Mark Gonzales of the Chicago Tribune reports.
Rosario has turned in four straight scoreless outings in the minors (5.1 innings), earning himself a promotion to the big club. Adbert Alzolay and Rowan Wick were optioned to Triple-A in corresponding moves.

Rosario made just one appearance during his latest big-league stint, although he failed to record an out. He walked in a run before getting yanked from Thursday's contest. In a corresponding move, the Cubs have recalled Dillon Maples.

Rosario will provide the Cubs with some pitching depth out of the bullpen during his latest stint in the big leagues. In a corresponding move, David Bote was placed on the paternity list.
Rosario was optioned to Triple-A Iowa on Sunday.
Rosario has a 27.3 percent strikeout rate, well above the 15.0 percent mark he recorded last season, but his ERA sits at 5.14. Alec Mills was recalled in a corresponding move.
Rosario has won the Cubs' final bullpen spot, Mark Gonzales of the Chicago Tribune reports.
Rosario stumbled to a 6.30 ERA in 10 spring innings, though he also struck out 11 batters while walking just three. The lefty threw 46.2 major-league innings last season, finishing with a strong 3.66 ERA but a mediocre 4.68 FIP.
Rosario has an 11.12 ERA and 2.12 WHIP through six appearances (5.2 innings) this spring.
With Brian Duensing struggling last season, Rosario emerged as a serviceable left-handed option. His 3.66 ERA, 1.48 WHIP and 30 strikeouts across 46.2 innings in 2018 don't paint the picture of a dominant reliever, but the Cubs don't have a ton of great alternatives at the moment, as fellow lefty Mike Montgomery is more of a long-relief option than a situational pitcher. Xavier Cedeno (wrist) could force his way into the role when he's healthy if Rosario struggles, however.
Rosario fired a perfect 10th inning, striking out one and earning his first save in Thursday's 4-3 win against the Nationals.
It was just Rosario's second save opportunity this season after he blew the first one in June. Pedro Strop (hamstring) left Thursday's contest with a possible injury, but Rosario would still be pretty far down the list of replacement closers.
Rosario pitched two scoreless innings of relief in Saturday's 3-1 loss to the Pirates. He allowed one hit and struck out one.
Rosario was thrust into action in the third inning after a short outing by starter Tyler Chatwood, and he kept the Cubs in the game. This was the lefty's first appearance since being recalled from Triple-A Iowa on Friday. He now has a 2.83 ERA this season and should continue to serve in a long relief role while Mike Montgomery (shoulder) is on the disabled list.
Rosario was recalled by the Cubs on Friday.
Mike Montgomery hit the disabled list with shoulder inflammation, bringing Tyler Chatwood back to the rotation and Rosario up to fill Chatwood's long-relief role. The lefty has a solid 3.00 ERA in 33 major-league innings this season, but the underlying numbers don't paint such a pretty picture. He's struck out just 14.8 percent of batters while walking 13.4 percent, leading to a 5.58 FIP.
Rosario was sent back down to Triple-A Iowa on Friday, Bruce Miles of the Daily Herald reports.
Rosario was cast off the active roster in order to make room for Jorge De La Rosa, who was signed by the club Friday morning. In a subsequent move, Yu Darvish (shoulder) was shifted to the 60-day DL. Rosario's last outing was a disaster, as he allowed four earned runs on four hits and two walks in one inning of relief. On the year, he's logged a 3.00 ERA and 1.52 WHIP with a rough 21:19 K:BB across 33 innings.

Rosario was sent down to Triple-A Iowa on Wednesday but has been resummoned just two days later with Brian Duensing heading to the disabled list with left shoulder inflammation. Rosario's 1.97 ERA is quite good, but his underlying statistics (5.11 FIP, 19:16 K:BB) support the idea that he's no better than the low-leverage role he'll likely find himself in again at Wrigley Field.

Rosario was cast off the 25-man active roster in order to make room for Brandon Kintzler. Across 26 appearances with Chicago this year, Rosario has logged a 1.97 ERA, but his 5.14 FIP and 4.5 BB/9 suggest he's greatly overachieved. That said, look for him to return to the fold when reinforcements in the bullpen are required.
Rosario (4-0) picked up the win in Saturday's 8-7 comeback victory over the Reds. He tossed 2.1 scoreless innings, allowing two hits and striking out two.
Rosario relieved an ineffective Tyler Chatwood in the sixth inning and kept the Cubs in the game. He helped his own cause with an RBI single in the bottom of the sixth and was then rewarded for his work when Chicago rallied for four runs in the eighth. Rosario has been a pleasant surprise for the Cubs this season, as he now has a 1.50 ERA across 24 innings.
Rosario was charged with a blown save in Thursday's loss to the Reds, as he allowed two earned runs on four hits while retiring just a single batter.
Rosario came in with the bases loaded in the sixth inning and promptly allowed a grand slam that put the Reds ahead 5-2. The lefty gave up three more hits and one more run before getting out of the inning and ending his disastrous outing. Rosario saw his ERA jump from 0.60 to 1.76 in the process.
Rosario (2-0) struck out one and grabbed the win Friday against the Mets, tossing 1.2 perfect innings.
The Cubs didn't score in this one until the seventh inning, which allowed Rosario to record his second win of the season after entering in the sixth for starter Tyler Chatwood. The lefty, who has bounced between the majors and minors this season, has yet to allow an earned run in seven innings with the Cubs. He should continue to serve in a middle-relief role for the time being.
Rosario was recalled from Triple-A Iowa on Saturday.
Yu Darvish (triceps tendonitis) hit the disabled list, so the Cubs needed some length in the bullpen in advance of what could be a quasi-bullpen game Monday. Rosario has a 0.47 ERA in 19.1 innings at Triple-A and has not given up a run in two innings in the big leagues. He has 15 strikeouts across 21.1 innings at the two levels and should work in the middle innings.
The Cubs optioned Rosario to Triple-A Iowa on Sunday, MLB.com reports.
Rosario's stay with the big club lasted just one day, as he joined the Cubs as their 26th man for Saturday's doubleheader with the Reds. The lefty wasn't needed out of the bullpen for either game of the twin bill and will now head back to Iowa, with whom he has produced a 0.52 ERA and 0.88 WHIP through 11 appearances this season.
Rosario was called up as the 26th man prior to Saturday's doubleheader, Mark Gonzales of The Chicago Tribune reports.
Rosario will provide a little extra depth within the Cubs' bullpen for Saturday's double dip before heading back to Triple-A Iowa. The left-hander recently joined the team Thursday, but was optioned to the minors in order to make room for Jason Heyward (concussion) on the active roster.
