The Mets placed Martinez on the paternity list Monday, Will Sammon of The Athletic reports.

Martinez will be allowed to spend up to three days away from the Mets as he spends time with his expanding family. To fill his spot on the active roster, DJ Stewart was recalled from Triple-A Syracuse.

Walker (oblique) will rejoin the Diamondbacks for this week's series in San Francisco, Jesse Friedman of GoPHNX.com reports.

It would appear he will be activated from the 10-day injured list during the series, perhaps as soon as Tuesday. Walker has been working out at the team's spring training complex in Arizona and got in some live at-bats over the weekend. The first baseman has been sidelined since late July with a left oblique strain.

Diamondbacks manager Torey Lovullo said Monday that Marte (ankle) could be activated from the 10-day injured list during the team's upcoming road trip, which begins Tuesday in San Francisco and ends Sunday in Houston, Jesse Friedman of GoPHNX.com reports.

Marte has been ramping up workouts in recent days and appears to be making significant progress. The second baseman has been sidelined since Aug. 19 due to an ankle sprain but looks to be on track for activation either mid-week or during the weekend.

The Reds designated Smith for assignment Monday.

Smith went 5-for-26 with four runs scored and 11 strikeouts over nine games during his time as a Red. He still holds a .691 OPS on the season through 307 plate appearances and could contribute for another team down the stretch, though he would not be eligible to play in the postseason. Ty France will presumably take over as Cincinnati's primary first baseman.

The Dodgers recalled Petersen from Triple-A Oklahoma City on Monday, Jack Harris of the Los Angeles Times reports.

Petersen will provide the bullpen with a fresh arm. He's allowed six runs over 12 relief innings during his time with the Dodgers this season.

The Dodgers optioned Wrobleski to Triple-A Oklahoma City on Monday, Jack Harris of the Los Angeles Times reports.

Wrobleski was pummeled for 10 runs over 5.1 frames in a start Sunday in Arizona. He was filling the rotation spot vacated by Clayton Kershaw (toe), and it's not clear what the Dodgers plan to do the next time Kershaw's spot comes up. They could summon another spot starter or perhaps go to a five-man rotation for one turn.

The Reds recalled Dunn from Triple-A Louisville on Monday.

Dunn went just 1-for-18 with seven strikeouts over his first two stints in the majors earlier this season, but he'll now be called upon to give the Reds some additional depth in the outfield. Dominic Smith was designated for assignment in a corresponding move.

Lux is not in the lineup for Monday's game in Arizona, David Vassegh of AM 570 LA Sports reports.

It's southpaw Eduardo Rodriguez toeing the rubber for the Diamondbacks, so the left-handed hitting Lux will begin this one on the bench. Chris Taylor will start at second base and bat ninth for the Dodgers.

Muncy is absent from the lineup for Monday's game in Arizona, David Vassegh of AM 570 LA Sports reports.

Muncy is not in strict a platoon, but he has now been on the bench three times in five games versus lefties since returning from the 60-day injured list last month. He served as a pinch hitter in one of those first two contests and will be a candidate to enter mid-game again Monday. Enrique Hernandez is getting the start at the hot corner in Monday's series finale.

Marte is not in the lineup for Monday's contest against the Astros.

He's fallen into a bit of a timeshare at third base with Santiago Espinal, who will start at the hot corner Monday. Marte had started each of the previous three games while Espinal was banged up, but Espinal was in the lineup for the three contests prior to that.
