Riley (abdomen) ran on the outfield and around the bases Sunday, and he seems likely to be activated from the injured list when first eligible Tuesday, Mark Bowman of MLB.com reports.

Riley's activity Sunday is another positive sign after he took batting practice Friday. The star third baseman was placed on the injured list with a right abdominal strain July 12, but he's said to be feeling better and optimistic about being able to return next week, possibly as soon as Tuesday when he's first eligible. While Riley has been out of action, Nacho Alvarez has been starting at third base for Atlanta.

Bregman is out of the lineup for Sunday's game against the Cubs, Christopher of Smith of MassLive.com reports.

As reported earlier in the weekend, the Red Sox are managing Bregman's playing time early on in his return from a quadriceps injury. Marcelo Mayer will start at third base in Sunday's series finale. Bregman is expected to start the first two games of the series against the Phillies on Monday and Tuesday.

Marte is starting in right field and batting seventh Sunday versus the Mets.

Marte has been the Reds' regular starter at third base, but Santiago Espinal is manning the hot corner Sunday while Marte is logging his first career appearance in the outfield. Per Charlie Goldsmith of Fox 19 Now Cincinnati, Marte began working in the outfield Saturday, as the Reds believe that having him in right while Espinal plays third base is a "stronger defensive alignment." Having Marte get experience in the outfield could also be a look toward a longer-term team construction, as prized third-base prospect Sal Stewart recently moved up to Triple-A.

Schmitt is out of the lineup for Sunday's game against the Blue Jays, Shayna Rubin of the San Francisco Chronicle reports.

Schmitt started eight straight games since returning from the injured list July 7, but he'll take a seat Sunday after going 4-for-27 during that stretch. Brett Wisely will step in at second base and bat eighth in the series finale.

Paredes (hamstring) said after Saturday's game against the Mariners that he's returning to Houston to undergo an MRI on Sunday, Brian McTaggart of MLB.com reports.

The 26-year-old departed Saturday's contest due to right hamstring discomfort and also said the injury feels worse than the left hamstring issue that sidelined him for a few games earlier this season. Manager Joe Espada said that the injury "doesn't look very good," per Matt Kawahara of the Houston Chronicle, so it wouldn't be surprising if a trip to the injured list is necessary. The Astros travel to Arizona on Monday to continue their road trip, and Paredes is likely to be out for at least the next couple days since he's travelling back to Houston for the evaluation.

Ramirez went 1-for-3 with a two-run home run and a walk Saturday in a loss to the Athletics.

Ramirez accounted for Cleveland's only runs of the contest with a two-run blast in the third inning. The All-Star third baseman has gone deep six times over his past 12 games, pushing his season total to 19 homers. With one more long ball, Ramirez will record the seventh 20-20 season of his career.

Suarez went 2-for-3 with two homers, three RBI and a walk in Saturday's 10-1 win over the Cardinals.

Suarez's power surge continued Saturday with two more home runs, bringing his season total to 33. The veteran third baseman now sports a .911 OPS and 81 RBI through 97 games. He's one of the most talked-about trade candidates ahead of the deadline and could bring back a significant return if the Diamondbacks decide to move him.

Hayes went 1-for-3 with a double, two RBI, a run scored and a walk Saturday against the White Sox.

Hayes ripped a two-RBI double into the right field gap in the fourth inning to account for both of his RBI. He's had a dismal season at the plate overall with a .577 OPS, though he has managed to go 22-for-82 (.268) with 14 RBI, 11 runs scored and a stolen base in the last month.

Shaw went 2-for-2 with a solo home run in Saturday's victory over Boston.

Shaw began Saturday's game on the bench but entered as a substitute for Vidal Brujan at third base and tallied two hits, including a solo homer in the seventh inning. The rookie has endured a rocky start to his MLB career, slashing .208/.283/.302 with 14 extra-base hits, 16 RBI and 12 stolen bases across 65 games. While the numbers are underwhelming, it's still too early to dismiss the once highly regarded prospect.

McMahon went 1-for-4 with a two-run home run in Saturday's 10-6 win over the Twins.

McMahon's third-inning blast tied the game at 3-3. He's come out of the All-Star break hot, homering in consecutive games while driving in a total of four runs. The infielder entered the break with just one long ball over his previous 20 contests, so it remains to be seen if he can keep his power trending upward. For the season, he has a .214/.309/.392 slash line with 15 homers, 32 RBI, 39 runs scored and two stolen bases over 96 contests as the Rockies' starting third baseman.
