Kieboom will start at third base and will bat eighth Monday against the Phillies.

The Nationals plan to stick with Kieboom as their everyday third baseman the rest of the season, but the early returns from the rookie haven't been overly impressive from a fantasy standpoint. Since becoming a lineup regular Sept. 5, Kieboom has slashed .213/.327/.234 with zero home runs, zero steals, seven runs and four RBI over 15 games.

Arenado is undergoing tests on a sore left shoulder Sunday and could miss the rest of the 2020 season, Patrick Saunders of The Denver Post reports.

Manager Bud Black said that the team should have more information regarding Arenado's shoulder issue Monday once the results of his tests are known. However, the soreness could force the 29-year-old to miss the final week of the regular season. If he's unable to play, Daniel Murphy and Garrett Hampson could see increased playing time as Ryan McMahon and Josh Fuentes could take over at third base.

The Pirates placed Newman on the 10-day injured list Sunday with a contusion to the peroneal nerve of his left knee, Jason Mackey of the Pittsburgh Post-Gazette reports.

The injury isn't believed to be especially significant, but the timing of Newman's placement on the IL means his 2020 campaign is over. The 27-year-old took a big step back this season, with his OPS dropping 242 points from his 2019 mark. Newman also failed to record a stolen base after going 16-for-24 on steal attempts last season. Adam Frazier and Erik Gonzalez will likely serve as Pittsburgh's everyday starters in the middle infield the rest of the way.

Hayes is out of the lineup for Sunday's game against the Cardinals.

The rookie went 2-for-4 with a double and homer in Saturday's 5-4 loss. JT Riddle will take Hayes' spot at third base in the series finale.

Arenado is not in the lineup for Sunday's game against the Dodgers.

Ryan McMahon will take over at third base as Kevin Pillar serves as the DH against right-hander Tony Gonsolin. Arenado recently dealt with an AC joint injury in his left shoulder, though there has been nothing yet to suggest this absence is directly related. Arenado is batting .218/.271/.309 with one home run so far in September.

Senzel is not in the lineup for Sunday's game against the White Sox.

Senzel had a double in Saturday's game, his first hit since coming off the injured list Monday (1-for-10). It's probably best to view Brian Goodwin as the Reds' primary center fielder, at least until Senzel is closer to full speed following his month-long absence.

Hayes went 2-for-4 with two runs scored and an RBI during the Cardinals' 5-4 win over the Pirates on Saturday.

Hayes has reached base in 15 of 17 contests since being called up while slashing a strong .310/.385/.603. The 23-year-old should remain a fixture toward the top of the Pirates' lineup as the regular season winds down.

McMahon is not in the lineup for Saturday's game against the Dodgers.

McMahon has sat frequently against southpaws recently, and he'll do so again here against one of the best in the league in Clayton Kershaw. Garrett Hampson will star at second base Saturday.

Segura (triceps) is back in the lineup as expected Saturday against Toronto, batting third and playing third base.

Segura was struck by a pitch in the triceps Thursday against the Mets and didn't appear in Friday's contest, though the injury was never expected to keep him out too long. He's gone 6-for-6 in his last two games and will look to stay hot in this one.

Newman went 0-for-4 with a pair of walks in Friday's doubleheader loss to the Cardinals.

He also made his seventh error of the season. Newman is batting .156 (5-for-32) since Sept. 9 with no extra-base hits. Prior to the season, he mentioned stealing bases as an area of expansion to his game, but he was unsuccessful in his lone attempt, and that was nearly two months ago. He dealt with an undisclosed injury during summer camp thought to be oblique related. For whatever reasons, his sophomore season has proven to be a disappointment: Newman is slashing .229/.281/.281 with one homer and 10 RBI in 168 plate appearances.
