Kirby (shoulder) will begin his rehab assignment with Triple-A Tacoma on Sunday, Adam Jude of The Seattle Times reports.

Kirby is in the final stages of his recovery from right shoulder inflammation that caused him to be placed on the 15-day injured list at the beginning of the season. He's slated to make his first rehab outing Sunday, and he'll need at least two or three starts in Triple-A before making his way back to the majors.

Volpe said after Saturday's 3-2 loss to the Rays that he felt a "pop" in his left shoulder in the eighth inning, Max Goodman of NJ.com reports.

Volpe injured his left shoulder while diving for a groundball, but he was able to stay in the game after being checked on by trainers. X-rays after Saturday's game came back clean, but the 24-year-old shortstop will undergo further testing and is in jeopardy of missing Sunday's series finale. Oswaldo Cabrera and Pablo Reyes could fill in at shortstop if Volpe were to be sidelined.

Taveras is out of the lineup for Saturday's game against the Mariners.

Taveras will give way to Dustin Harris in center field Saturday after going 0-for-3 with two strikeouts during Friday's series opener.

Dunning cleared waivers Saturday and was sent outright to Triple-A Round Rock.

Dunning will officially stick with the organization after being dropped from the 40-man roster Wednesday. He's made five starts in the minors so far this season, posting a 5.40 ERA and 1.55 WHIP across 20 innings, and he could be in consideration for a move back to the Rangers if the big club's pitching depth is tested down the road.

The Rangers optioned Ornelas to Triple-A Round Rock on Saturday.

Ornelas was brought onto the active roster Friday to replace Nick Ahmed but will now head back to the minors to make room for Corey Seager, who was activated from the IL on Saturday. Ornelas hasn't had much success at the plate this season, going 0-for-5 during his brief stints in the majors and logging a .414 OPS across 67 Triple-A plate appearances.

The Rangers reinstated Seager (hamstring) from the injured list Saturday.

Seager has been out of action since April 23 due to a strained right hamstring, but the 10-day minimum is all he needed to make a full recovery. He'll slide back into his usual role as Texas' everyday shortstop and look to pick up where he left off after slashing .302/.362/.524 during April. Jonathan Ornelas was optioned to Triple-A Round Rock in a corresponding move.

The Orioles placed Urias on the 10-day injured list Saturday due to a right hamstring strain, Jake Rill of MLB.com reports.

Urias' hamstring has prevented him from playing since Friday, and now that he's on the IL, it will continue to keep him on the sidelines until at least May 13. Coby Mayo was recalled from Triple-A Norfolk in a corresponding move and will presumably get regular work at third base until Urias or Jordan Westburg (hamstring) returns.

The Orioles recalled Mayo from Triple-A Norfolk on Saturday, Jake Rill of MLB.com reports.

Mayo will likely receive regular reps at the hot corner while Jordan Westburg and Ramon Urias are both on the injured list due to hamstring injuries. Mayo, 23, struggled upon reaching the majors last season, going just 4-for-41 with 22 strikeouts, but he's since bounced back in Triple-A by posting a .869 OPS through 127 plate appearances this year.

Waters is out of the lineup for Saturday's game against Baltimore.

Waters' 0-for-3 performance Friday put an end to his brief four-game hitting streak, and he'll now get a chance to rest against Patrick Corbin and the Rangers. Hunter Renfroe will fill the resulting void in right field and bat sixth.

Perez (hip) isn't in the lineup for Saturday's game against the Orioles.

Perez will miss a second consecutive game Saturday after leaving Thursday's contest due to left hip soreness. Freddy Fermin will get the nod at catcher and bat eighth, and Cavan Biggio will work as Kansas City's designated hitter while batting seventh.
