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.

Nunez is out of the lineup for Monday's game against the Mets.

Nunez has remained a fantasy asset with a National League-best 19 steals in 21 attempts on the season, but his lack of production at the plate may be starting to cost him some playing time. He'll head to the bench for the second time in four games while he's mustered a lowly .162/.289/.216 slash line since the beginning of May.

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.

The Kiwoom Heroes signed Hiura to a one-year, $400,000 contract Monday, Jee-ho Yoo of South Korea's Yonhap News Agency reports.

He can earn an additional $100,000 in incentives. Hiura was a non-roster invitee by the Dodgers during spring training but was released before the minor-league season began. He'll now head overseas to continue his playing career.

Castro went 1-for-3 with two RBI and a double Sunday against the Diamondbacks.

Castro doubled in a run in the fourth inning and picked up his second RBI of the game four frames later on a sacrifice fly. He snapped out of a five-game hitless streak Saturday and now has three hits across 10 at-bats with two RBI and two runs scored in three contests to begin Colorado's current homestand. Castro is hitting only .236 for the season, though he does have 20 runs scored and 15 RBI in his 38 contests.

Arraez went 3-for-4 with a solo home run, an additional run scored and a walk in Sunday's 10-1 victory over the Athletics.

Arraez stayed hot in the Giants' victory, tallying three hits, highlighted by a solo homer to open the scoring in the third inning. It has been a strong May for the second baseman, who is slashing .375/.444/.589 with two homers, six doubles, five RBI and 10 runs across 14 contests this month. With Sunday's performance, Arraez's season OPS climbed to .807 through 44 games.
