McLain went 1-for-2 with two walks and a solo home run in Sunday's 7-4 win over St. Louis.

McLain gave the Reds insurance in the eighth inning, when he knocked his 13th homer and second in as many days. It's been a trying season for the middle infielder, who's batting .222 for the season and spent a good deal of the first half below the Mendoza Line (.200). His playing time may take a hit with the expected arrival of top prospect Sal Stewart, who came through the system as a third baseman but has been introduced to second base this season.

Lawlar started at third base and went 0-for-4 in Sunday's 5-4 loss to the Dodgers.

Lawlar was back in the lineup after getting a day off Saturday. The right-handed batter has made two starts since his recent call-up, once against a lefty and Sunday's start against a righty. Arizona manager Torey Lovullo said over the weekend that he will mix-and-match Lawlar and Blaze Alexander at third base against righties but will use Lawlar against all lefties. He had a couple more strikeouts Sunday, upping his count to 14 over 30 plate appearances (46.7 percent) this season.

Marte started at designated hitter for a third consecutive game and went 2-for-4 with two runs scored in Sunday's 5-4 loss to the Dodgers.

It appears manager Torey Lovullo is managing Marte, who has no reported injury. Tender hamstrings have been a recurring feature throughout Marte's career, and he missed a month of action earlier this season because of a hamstring issue. Having him DH appears to be a ploy that can get his bat in the lineup while also giving younger players, like Jordan Lawlar and Blaze Alexander, plate appearances.

Schmitt is out of the lineup for Sunday's game against the Orioles.

Christian Koss will fill in for Schmitt at second base in the series finale. Schmitt will get a chance to clear his head after he slashed just .170/.235/.340 with a 25.5 percent strikeout rate while starting in each of the Giants' last 12 games.

Hoerner is out of the lineup for Sunday's game against the Rockies.

Hoerner will receive a breather after starting 11 straight games while slashing .275/.333/.425 with a home run, a stolen base, six RBI and six runs. Willi Castro will step in for Hoerner at the keystone.

Garcia is out of the lineup for Sunday's game against the Rays.

The left-handed-hitting Garcia was included in the lineup for Wednesday's 11-2 loss to the Yankees while New York sent southpaw Max Fried to the hill, but the infielder will hit the bench Sunday versus Rays lefty Ian Seymour. With Garcia out of the lineup, Paul DeJong will receive the starting nod at the keystone.

McLain went 1-for-4 with a solo home run in Saturday's 4-2 loss to the Cardinals.

McLain's seventh-inning home run brought the Reds within a run, but they couldn't complete the comeback. The homer was his 12th of the season, but his first since July 18 and just his fifth extra-base hit in the second half. August hasn't been kind to McLain, who has a .219/.254/.281 slash line over 21 games this month.

Iglesias will start at shortstop and bat eighth in Sunday's game against the Twins.

With Xander Bogaerts landing on the injured list Friday due to a non-displaced left foot fracture, Iglesias has gained some traction in the San Diego infield. The 35-year-old will pick up his fourth consecutive start Sunday after going 3-for-12 with an RBI and a run scored over the previous three contests.

Marte started at designated hitter and went 1-for-3 in Saturday's 6-1 win over the Dodgers.

Marte served as the DH for a second consecutive game, which could become a normal deployment over the final month of the season, per Alex Weiner of Arizona Sports. Manager Torey Lovullo indicated that Jordan Lawlar would stick at third base down the stretch while Blaze Alexander shifted into a super-utility player. That opens up the possibility of using Alexander at second base and reducing the wear and tear on Marte while maintaining his bat in the lineup as the DH. Additionally, utility infielder Ildemaro Vargas, who started at second base and homered Saturday, is also around to give Marte a break.

Vargas went 2-for-4 with a three-run home run in Saturday's 6-1 win over the Dodgers.

Vargas logged his first multi-hit effort since his Aug. 18 return from a foot injury. He's gone 5-for-23 with two extra-base hits and six RBI over his last eight contests, and his homer Saturday was just his second of the year. The infielder has added a .255/.269/.451 slash line with 10 RBI, six runs scored, two doubles, one triple and no stolen bases across 52 plate appearances. Vargas remains in a part-time role, though he has multiple paths into the lineup due to his defensive versatility.
