Duffy (hamstring) will begin a minor-league rehab assignment with High-A Charlotte on Friday, Marc Topkin of the Tampa Bay Times reports.

Duffy has been sidelined all season due to a hamstring injury, but he's finally been cleared to head out on a rehab assignment after getting a sufficient amount of at-bats in during extended spring training games over the past few days. The third baseman is expected to spend the next 7-to-10 days with the Stone Crabs before being reevaluated.

Manager Brian Snitker said Donaldson (calf) should be good to go for the Braves' weekend series against the Marlins, Gabe Burns of The Atlanta Journal-Constitution reports.

It sounds like Donaldson is on track to rejoin the starting lineup against the Marlins over the weekend after missing a trio of games due to a sore right calf. The veteran third baseman is slashing .258/.395/.495 with five homers through 28 games this season.

Kieboom is not in the lineup Thursday against the Cardinals.

Kieboom has gone just 3-for-22 (.136) with a pair of homers and nine strikeouts in six games since earning a promotion near the end of April. As such, he'll take a seat for Thursday's series finale as he looks to hit the reset button. Wilmer Difo is starting at shortstop and hitting eighth in his place.

Chapman went 2-for-4 with a double and a run in a loss to the Red Sox on Wednesday.

Chapman got the new month off to a strong start with his second two-hit effort of the last three games. The 26-year-old third baseman has reached safely in four of his last five contests overall, and he's coming off a productive month of April during which he drove in 16 runs with the aid of 12 extra-base hits (five doubles, seven home runs).

Donaldson (calf) remains out of the lineup for Thursday's game against the Padres.

Donaldson's sore right calf will keep him on the bench for a third straight day. According to Mark Bowman of MLB.com, Donaldson will at least be available as a pinch hitter, offering optimism that he'll be able to avoid the injured list and rejoin the lineup at some point this weekend in Miami. Johan Camargo will man third base in his absence in the series finale with San Diego.

Riley went 4-for-5 with a double, two solo home runs and a third run scored for Triple-A Gwinnett on Wednesday.

His second blast actually cleared the left-field scoreboard at Coolray Stadium, traveling an estimated 492 feet. Riley is on fire right now, going yard five times in the last six games while slashing a dizzying .542/.577/1.333. He's blocked from a promotion as long as Josh Donaldson is healthy, but the 22-year-old is making a strong case that he's just about ready to face big-league pitching.

Arenado went 3-for-5 with two home runs and four RBI in Wednesday's 11-4 win over the Brewers.

The third baseman's sluggish start at the dish is a distant memory. Arenado is now slashing .285/.328/.553 through 30 games, but he's racked up six multi-hit efforts and five of his eight homers on the year in his last 10 contests.

Machado went 1-for-4 with a solo home run in the Padres' 5-1 defeat to the Braves on Wednesday.

It's been a slow start to the season for Machado, but he managed to check in with his fifth long ball of the season in this contest, touching up Max Fried with a fourth-inning solo blast for his team's only run on the day. It was his first time leaving the yard since April 12 and Machado is still slashing just .236/.323/.391 through his first 110 at-bats with the Padres. However, he can heat up in a hurry, so hopefully this is a sign he's set to get on track.

Muncy will start at first base and bat sixth against the Giants on Wednesday, Alanna Rizzo of Spectrum SportsNet LA reports.

Muncy was originally stationed on the bench with Madison Bumgarner on the mound for the Giants, but makes his way into the starting nine with David Freese scratched with a sore ankle. Muncy has hit lefties quite well in limited opportunities this season with a .292/.370/.708 slash line and two home runs in 27 plate appearances.

Muncy is not in the lineup Wednesday against the Giants.

Muncy will take a seat for Wednesday's series finale against the Giants with southpaw Madison Bumgarner starting for the opposition. David Freese is starting at first base and hitting fifth in his place.
