Alvarez went 2-for-3 with a double and an RBI in Monday's extra-inning loss to the Cubs.

The 22-year-old infielder has picked up the pace at the plate, and over his last 16 games Alvarez is slashing .288/.344/.373 with five doubles, five RBI and seven runs. He should remain the starting third baseman for the rest of the season with Austin Riley recovering from core muscle surgery, but Alvarez's lack of power or speed limits his fantasy potential even in a full-time role.

Marte went 1-for-5 with two RBI in Monday's 5-4 win over the Blue Jays.

The Reds squandered a lead in the top of the ninth inning but mounted their own comeback in the bottom of the frame. Marte finished it with a two-run single to walk off Toronto. He's scuffled the last week, batting .200 (6-for-30) with a 36.4 strikeout percentage, but Marte has delivered key hits during that run, including two home runs in addition to Monday's heroics.

Alexander started in center field and went 1-for-4 with a triple, an RBI and a run scored in Monday's 7-5 extra-inning loss to the Rangers.

Arizona manager Torey Lovullo discussed Alexander's shifting role last week, including time in the outfield. The outfield skews lefty, particularly in center field, and Alexander gives the manager a right-handed option against southpaws, as was the case Monday against Texas lefty Patrick Corbin. Alexander then showed off his versatility by playing left field when Lourdes Gurriel (knee) was removed, and he eventually also played third base by the end of the game. He's been on a roll over the last week, going 7-for-21 with five extra-base hits, five RBI, one steal and seven runs scored over the last six contests.

Shaw went 2-for-3 with a walk, a double, a stolen base and an RBI in Monday's 7-6, extra-inning win over Atlanta.

After an encouraging August in which he batted .240 with an .839 OPS and five home runs across 28 games, Shaw got off to a good start in September. The rookie only swiped one base last month, but he's now got 16 steals overall this season in 19 attempts. Shaw continues to exhibit some growing pains as a 23-year-old, though his mix of power and speed gives him plenty of fantasy upside.

Atlanta transferred Riley (abdomen) from the 10-day injured list to the 60-day IL on Monday.

The transaction frees a spot on the 40-man roster for the addition of Ha-Seong Kim (back), who was claimed off waivers from the Rays on Monday. Riley underwent season-ending core surgery nearly two weeks ago and is expected to be ready for spring training.

Bohm is absent from the lineup for Monday's game in Milwaukee.

Bohm put together an 11-game hitting streak upon his return from the injured list Aug. 17, but he'll get a breather Monday after going hitless in his last three contests. Edmundo Sosa will start third base and bat eighth for the Phillies.

Arenado will join the Cardinals in St. Louis on Wednesday and have his injured right shoulder examined Thursday, John Denton of MLB.com reports.

If he gains clearance from team doctors, Arenado will go through a pregame workout with the team Thursday and then possibly go out on a rehab assignment. The veteran third baseman has been shelved since late July with a right shoulder strain but could be back on the Cardinals' active roster by mid-September.

Chapman (shin/foot) will start at third base and bat fifth Monday in Colorado, Susan Slusser of the San Francisco Chronicle reports.

Chapman fouled a ball off his foot/shin during Sunday's 13-2 win over the Orioles and exited the game early, but he expressed optimism that he wouldn't miss further time. As anticipated, Chapman will check back into the lineup as the Giants kick off a three-game series in Coors Field.

DeJong is out of the lineup for Monday's game against the Marlins.

DeJong will hit the bench after he had started in each of the last three games while going 2-for-11 with seven strikeouts. Though DeJong should be a fixture in the lineup against left-handed pitching throughout September, his playing time versus righties may be more sporadic so long as the Nationals stay committed to giving third baseman Brady House regular starts.

Arcia went 3-for-4 with an RBI and a run scored Sunday against the Cubs.

Arcia has started every other game across Colorado's last six contests, filling in primarily at second base. He drew a start at third base Sunday and delivered an RBI single in the fourth inning. Arcia has gone 8-for-23 with five RBI and three runs scored since returning from the injured list Aug. 17.
