Stefanic was sent outright to Triple-A Las Vegas on Monday, Jason Burke of SI.com reports.

Stefanic was booted from the 40-man roster Saturday, and after going unclaimed on waivers, he'll head to Triple-A. The 30-year-old appeared in two games for the A's and went 2-for-5 with one run scored during his brief time with the big-league club.

The Rangers recalled Helman from Triple-A Round Rock on Monday.

Helman has spent all of this season with Round Rock, where he's slashed just .198/.291/.344 in 37 tilts. The 29-year-old had some nice moments with the Rangers last season and could net some starts versus left-handers.

The Astros placed Altuve on the 10-day injured list Monday with a left oblique strain.

Altuve has been diagnosed with a Grade 2 strain after injuring his oblique on a swing in Saturday's game versus the Rangers. The club has not offered a timeline for Altuve's return, but moderate oblique strains typically result in absences of at least 4-to-6 weeks. Brice Matthews should receive the bulk of the playing time at second base for Houston while Altuve is out.

Palacios is out of the lineup for Monday's game against the Orioles, Marc Topkin of the Tampa Bay Times reports.

After he had been included in the lineup in each of the last four games while the Rays faced right-handed starters, the left-handed-hitting Palacios will take a seat against Orioles southpaw Trevor Rogers in the series opener. Carson Williams will spell Palacios at second base and will bat ninth.

Rays manager Kevin Cash said that Williamson is not in the lineup for Monday's game versus the Orioles due to back tightness, Ryan Bass of Rays.tv reports.

Williamson hasn't played since last Friday and hasn't started a game since last Tuesday, though it's unclear whether it's the back issue that's kept him out during that stretch. Cash noted that Williamson felt improvement Monday, but the manager also didn't rule out a stint on the injured list. Consider Williamson day-to-day for now.

Caballero (finger) played catch Monday, Gary Phillips of the New York Daily News reports.

Caballero has also done some fielding drills in recent days, but Monday marked the first time that he has thrown since fracturing his right middle finger May 10. Yankees manager Aaron Boone reiterated Monday that Caballero still has a chance to be activated from the 10-day injured list Thursday when first eligible, but a decision will depend on how Caballero fares in workouts over the next couple of days. Caballero is expected to reclaim the team's starting shortstop job when he returns, which will likely push Anthony Volpe back to the minors.

Mariners general manager Justin Hollander said Sunday that Donovan will receive a platelet-rich plasma injection for his strained left groin as well as his adductor and is expected to resume baseball activity in 2-to-3 weeks, Daniel Kramer of MLB.com reports.

Seattle placed Donovan on the 10-day injured list Sunday, and given that he won't be on track to resume on-field activity for at least another two weeks, he's not a candidate to return to action when first eligible May 26 and will see his absence extend into June. Donovan previously missed about three weeks of action earlier this season after straining the same groin, so the Mariners could proceed more cautiously with bringing him back from the shelf this time around. For however long Donovan is out of action, Colt Emerson is expected to serve as the Mariners' everyday third baseman.

Duran started at shortstop and went 1-for-4 with a double and a run scored in Sunday's 8-0 win over the Astros.

Duran, who had been filling in for injured second baseman Josh Smith (thigh/wrist/illness), has been shifted to shortstop the last three games with Corey Seager (back) unavailable. Seager is headed back to Texas for an MRI, and Duran should be in the lineup most days with the Rangers' middle infield sidelined.

The Mariners placed Donovan on the 10-day injured list Sunday due to a left groin muscle strain, Ryan Divish of The Seattle Times reports.

Donovan had already been left out of the starting nine for a second straight game Sunday against the Padres, but he'll now wind up being shelved until at least May 26 while he tends to an aggravation of the injury that previously sent him to the IL back on April 20. In a corresponding move, the Mariners called up top prospect Colt Emerson from Triple-A Tacoma. Emerson will start at third base Sunday in his MLB debut and should serve as the top option at the position while Donovan is on the shelf.

Manager Joe Espada announced after Sunday's loss to the Rangers that Altuve was diagnosed with a Grade 2 left oblique strain and will be placed on the injured list, Chandler Rome of The Athletic reports.

Espada didn't offer an official return timeline, but the veteran second baseman seems likely to be sidelined for at least a month given the severity of the strain. Brice Matthews picked up a start at second base Sunday for Houston, but Braden Shewmake and Shay Whitcomb are also likely to be factors at the keystone while Altuve is out.
