The Yankees designated Alexander for assignment Monday.

The transaction frees up a spot on the 40-man roster for right-hander Geoff Hartlieb, who was called up from Triple-A Scranton/Wilkes-Barre. Alexander was a waiver pickup of the Yankees earlier this month and will now go through the waivers process again.

The Red Sox reinstated Mayer (personal) from the bereavement list Monday. Mayer will start at third base and bat sixth in the Red Sox's series opener with the Reds.

After being recalled from Triple-A Worcester on Friday when Mayer was deactivated, infielder Nick Sogard will head back to the minors to clear room for Mayer's return to the 26-man active roster. Before stepping away from the team and missing three games while tending to the personal matter, the 22-year-old rookie slashed .208/.262/.429 with four home runs and seven RBI through his first 84 big-league plate appearances. At least until Alex Bregman (quadriceps) returns from the injured list, Mayer is poised to serve as the Red Sox's primary third baseman.

Arenado (finger) will start at designated hitter and bat fifth in Monday's game against the Pirates.

After jamming his right index finger early in Sunday's 7-0 win over the Guardians, Arenado initially stayed in the game before he was lifted for a pinch hitter in the eighth inning. The Cardinals described Arenado's early exit as precautionary, and his inclusion in the lineup a day later seemingly supports that notion. While the veteran third baseman is on pace for a second straight season with a sub-.400 slugging percentage, he's at least gotten his batting average back on track in June, hitting .283 through his first 26 games of the month.

Chapman (hand) is hoping to be activated from the 10-day injured list for the July 11-to-13 series against the Dodgers, MLB.com reports.

Chapman has progressed to hitting off a tee and throwing as he recovers from a right hand sprain. He's already missed three weeks of action, and while his rehab is coming along, Chapman has a few more items on his checklist before he can be activated. With Casey Schmitt (wrist) also banged up, the Giants have been using Christian Koss at third base of late.

Moncada (knee) has been sent to the rookie-level Arizona Complex League Angels to begin a rehab assignment, MLB.com reports.

Moncada's recovery from right knee inflammation has dragged on longer than expected, but he is finally ready to play in games again. The veteran infielder should eventually move up to a higher minor-league affiliate as he continues his rehab assignment and could return in early July.

Barger went 1-for-4 with a solo home run in Sunday's win over the Red Sox.

The 25-year-old got the Blue Jays on the board in the first inning, going back-to-back with Vladimir Guerrero off Walker Buehler. Barger has slowed down at the plate in June after breaking out in May, but through 90 plate appearances this month he's still slashing a respectable .250/.300/.512 with five of his nine homers on the season, along with 12 RBI and 16 runs.

Bride was designated for assignment by the Twins on Sunday, Betsy Helfand of the St. Paul Pioneer Press reports.

Bride got the start at third base in Sunday night's 3-0 loss to the Tigers and went 0-for-2 with one strikeout before he was pinch-hit for in the eighth inning. In 80 trips to the plate with Minnesota, Bride slashed a miserable .170/.248/.188 with just two doubles, three RBI, four runs scored and a 6:23 BB:K. Royce Lewis (hamstring) is a logical candidate to be activated from the 10-day injured list with Bride removed from the 40-man roster.

Hayes went 3-for-5 with two doubles, two RBI and three runs scored in Sunday's win over the Mets.

Hayes got things going early with a two-run single and a run scored in the first inning. He later doubled and scored in the fifth and seventh frames. He's on an eight-game hitting streak and collected multiple hits in each contest during the Pirates' three-game sweep of the Mets. Hayes has gone 13-for-29 (.448) during his hitting streak, raising his season slash line to .246/.297/.305 through 307 plate appearances.

DeJong (orbital) will return to Washington and could be activated off the 10-day injured list ahead of Tuesday's series opener against the Tigers, Andrew Golden of The Washington Post reports.

DeJong landed on the IL in mid-April after he fractured his nose and orbital bone when he was hit in the face by a pitch from the Pirates' Mitch Keller. After undergoing surgery to address the injury, DeJong was cleared for a rehab assignment in mid-June, and in 12 games with Double-A Harrisburg, he has slashed .275/.348/.375 with one steal and one home run. The 31-year-old had been serving as the Nationals' primary third baseman prior to getting hurt, but he may have to settle for a utility role upon his return if Washington remains committed to letting rookie Brady House play regularly.

Single-A Kannapolis activated Albertus (tibia) from its 7-day injured list Tuesday.

Albertus has yet to make his debut for Kannapolis, but he's apparently healthy again after he recently wrapped up an eight-game rehab assignment in the rookie-level Arizona Complex League, during which he slashed .333/.520/.444 with three stolen bases across 25 plate appearances. Acquired last July in a three-team deal with the Dodgers and Cardinals, Albertus didn't make his organizational debut with the White Sox until earlier this month while completing his recovery from surgery to reset a fractured left tibia.
