The Red Sox recalled Eaton from Triple-A Worcester on Monday.

Eaton will join the 26-man active roster in place of Rob Refsnyder (oblique), who was placed on the 10-day injured list. The utility player previously went 6-for-24 with three stolen bases over 14 games with the big club earlier this season. The right-handed-hitting Eaton is unlikely to see many starts versus right-handed pitching, but he could have a regular spot in the lineup versus lefties. He'll serve as Boston's designated hitter and leadoff batter in Monday's matchup with Orioles southpaw Trevor Rogers.

The Marlins placed Pauley on the 10-day injured list Monday with a right oblique strain.

Miami hasn't shed light on the severity of the injury that Pauley sustained over the weekend, but given that even mild oblique strains typically entail more than a 10-day recovery, the 24-year-old is unlikely to return from the IL when first eligible Aug. 27. Miami recalled infielder Maximo Acosta from Triple-A Jacksonville in a corresponding move, but Javier Sanoja and Eric Wagaman may be likelier candidates to pick up starts at third base while Pauley is on the shelf.

The Mariners optioned Mastrobuoni to Triple-A Tacoma on Monday.

Mastrobuoni was designated as the Mariners' 27th man for Sunday's 7-3 loss to the Mets in the Little League Classic in Williamsport, Pa. and did not appear in the contest. He's heading back to Tacoma as the Mariners return to a standard 26-man active roster ahead of Monday's series opener in Philadelphia.

Dodgers manager Dave Roberts said that Muncy's (oblique) condition is improving, and the 34-year-old is scheduled to take part in some "rotational" work Monday, Fabian Ardaya of The Athletic reports.

Though Muncy's oblique strain is of the mild variety, the Dodgers are still expecting him to miss more than the minimum 10 days after he landed on the injured list Friday. Muncy is still in the early stages of his recovery program, so a clearer timeline for his return from the IL is unlikely to become available until he's able to take part in full baseball activities. While Muncy has been out of action for the Dodgers' last four games, Alex Freeland has made three starts at third base and Buddy Kennedy has made one start.

Marte went 2-for-4 in Sunday's 3-2 extra-inning win over Milwaukee.

Marte extended a hit streak to eight games, during which he's gone 15-for-34 (.441) with five doubles, two home runs, nine RBI and six runs scored. The transition from third base to outfield hasn't been an issue, as Marte is slashing .333/.333/.515 over 17 appearances in right field.

Vientos went 2-for-3 with a three-run home run and an additional RBI in Sunday's 7-3 win over the Mariners in the Little League Classic.

Vientos supplied a sacrifice fly in the second inning and then took one out in the fifth. It was Vientos' first homer since July 28. The third baseman has started two of the last three games for the Mets after sitting out four straight contests amid a slump. He's struggled this year, slashing .232/.276/.372 with eight homers, 36 RBI, 26 runs scored, 14 doubles and two triples over 84 contests. Vientos will likely continue to compete with Ronny Mauricio and Brett Baty for time at the hot corner.

Westburg went 4-for-5 with a home run, five RBI and two runs scored in Sunday's win over Houston.

Westburg led the charge in Baltimore's 12-0 victory with five RBI, including three with his fifth-inning homer. He later knocked RBI singles in the seventh and eighth frames. Westburg has at least three hits in three of his last 18 games, going 26-for-74 (.351) during that span. He's now slashing .277/.327/.475 with 15 home runs and 34 RBI through 72 games.

Pauley wasn't available for Sunday's 5-3 win over the Red Sox due to right side tightness, Christina De Nicola of MLB.com reports.

Even if he was fully healthy, the left-handed-hitting Pauley likely would have sat out Sunday anyway while lefty Garrett Crochet took the hill for the Red Sox, but the injury now threatens the third baseman's availability for the Marlins' upcoming series with the Cardinals that begins Monday. If Pauley's side issue is deemed serious enough to send him to the injured list, Infielder Maximo Acosta could be called up from Triple-A Jacksonville in a corresponding move.

The Red Sox are expected to recall Eaton from Triple-A Worcester prior to Monday's game against the Orioles, Andrew Parker of Beyond the Monster reports.

Boston won't announce the roster move until Monday, but the Wilyer Abreu (calf) could be a candidate to go on the injured list in a corresponding transaction. Eaton has previously seen action in 14 games with Boston this season, slashing .250/.296/.333 with three stolen bases over 27 plate appearances.

DeJong went 1-for-4 with a three-run home run and an additional run scored during Sunday's 11-9 loss to the Phillies.

DeJong tried to spark a comeback Sunday, tagging Max Lazar for a three-run home run in the bottom of the ninth to make it a two-run game. His long ball prompted the Phillies to insert closer Jhoan Duran, who immediately shut the door. DeJong has been on a heater recently, having hit five home runs in his last 10 games and going 12-for-39 (.308) during that stretch.
