The Royals outrighted Rosario to their alternate training site Sunday.

EDGE Analysis

Rosario will stick around in the Kansas City organization after he went unclaimed off waivers when he was designated for assignment Thursday. Before being dropped from the 40-man roster, Rosario made four relief appearances for the Royals, giving up three runs on seven hits and three walks over 3.1 innings.

Rosario was designated for assignment by the Royals on Thursday.

EDGE Analysis

Rosario tossed 1.2 scoreless innings in his first two outings this season. However, his results declined over his most recent two appearances, and the southpaw now carries an 8.10 ERA and 3.00 WHIP over 3.1 innings this year. He'll be removed from the 40-man roster to make room for Edward Olivares in the major-league outfield.

Rosario (arm) was activated from the 10-day injured list Friday, Alec Lewis of The Athletic reports.

EDGE Analysis

Rosario had been out since the start of the season with arm tightness. He's evidently past the issue now, however, and will provide the Royals with a left-handed option out of the bullpen. He's unlikely to be a high-leverage arm, however, as he owns a career 4.83 ERa in 63.1 major-league innings. Salvador Perez (eye) was placed on the injured list in a corresponding move.

Rosario (arm) was placed on the 10-day IL on Thursday, Jeffrey Flanagan of MLB.com reports.

EDGE Analysis

This was expected, as Rosario is still battling tightness in his arm. He'll be eligible to return from the IL at the end of July, though it's unclear if he'll be ready to go by then. He should assume a spot in the middle of Kansas City's bullpen once healthy.

Rosario won't begin the regular season on the 30-man roster while dealing with arm tightness, Lynn Worthy of The Kansas City Star reports.

EDGE Analysis

Rosario won a spot in the bullpen during spring training, but he'll be sidelined to begin the year. It's unclear how or when he suffered the injury, and how much time the southpaw misses remains to be seen. Rosario posted a 4.40 ERA and 13:5 K:BB over 14.1 innings with the Cubs and Royals in 2019.

Rosario had edged into the lead for the final spot in the Royals' bullpen when camp was suspended, Jeffrey Flanagan of MLB.com reports.

EDGE Analysis

He was competing with nine other pitchers for the Royals' ninth spot in the bullpen, although they didn't project to need a fifth starter in the first couple weeks, so they may only carry eight relievers when play resumes. Rosario gave up one earned run on two hits and one walk while striking out three in 6.1 innings. He is out of minor-league options.

Rosario was claimed off waivers by the Royals on Thursday, Jeffrey Flanagan of MLB.com reports.

EDGE Analysis

Rosario will join the Royals after being designated by assignment by the Cubs earlier in the week. The lefty owns a 5.91 ERA, 1.59 WHIP and 10:5 K:BB across 10.2 big-league innings this season. Kelvin Gutierrez (toe) was placed on the 60-day IL in a corresponding move.

Rosario was designated for assignment by the Cubs on Monday, Jesse Rogers of ESPN.com reports.

EDGE Analysis

Nico Hoerner was added to the 40-man roster in a corresponding move. Rosario posted a 5.91 ERA and 1.59 WHIP with 10 strikeouts over 10.2 innings this season in the majors.

Rosario was optioned to Triple-A Iowa on Friday.

EDGE Analysis

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 trades for 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.

EDGE Analysis

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.
