The Chicago Cubs are promoting veteran righty Shane Greene from Triple-A Iowa, sources tell ESPN.

Greene, 34, will be added to the team as rosters expand to 28 for September. He has been working as a starter in the minors and could be on the mound for one of the team's doubleheader games against the Cincinnati Reds on Friday.

The Los Angeles Dodgers recalled right-hander Ryan Pepiot from Triple-A Oklahoma City, and the rookie started Wednesday's home game against the Arizona Diamondbacks, throwing five scoreless innings in the 7-0 victory.

Pepiot got the win, allowing two hits, walking one and striking out three batters on 84 pitches.

The Chicago White Sox have promoted Chris Getz to general manager.

The club parted ways with Ken Williams and Rick Hahn last week. Getz has been named senior vice president and general manager, the same two titles held by Hahn before he was fired.  

Getz, 39, has for the past seven years guided the White Sox's minor-league operations and player-development system. He's been the assistant GM for the past three years.

The Houston Astros won their fifth-straight game with Wednesday's victory over the Boston Red Sox.

During the surge they have a franchise-record 78 hits and remain tied atop the American League West standings. They also swept the Red Sox at Fenway Park for the first time in franchise history.

"We've been there and done that for a long time -- the past seven years," said closer Ryan Pressly. "I think this is kind of when we turn it on. This team, we're built to win championships and to go deep in the playoffs. We know what it takes to get there and we've just got to string good innings and good at-bats together, and just keep doing what we're doing right now and things will take off."

With 30 games remaining, the Atlanta Braves have already set a new franchise mark for single-season home runs.

Orlando Arcia drew the honor of hitting the record-setting 250th home run in the sixth inning of the Braves' 7-3 win over the Colorado Rockies on Wednesday night at Coors Field. 

Atlanta has 40 more homers than any other club.

They are on pace to hit 306 home runs, which would be one short of the Major League record set by the 2019 Minnesota Twins.

The New York Mets will call up prospect Ronny Mauricio when rosters expand to 28 players on Friday, according to a report.

Mauricio, 22, has hit .295/.349/.511 with 23 home runs, 30 doubles, and 24 stolen bases for Triple-A Syracuse this season.

Largely a middle infielder, he has also seen time in left field.

Coming into the 2022 season, Mauricio was a consensus top-100 overall prospect. 

With the New York Yankees now focused on seasons beyond the disaster of 2023, they have informed top outfield prospect Jasson Dominguez that he will be activated on Friday, sources confirmed, in time for the team's series against the Houston Astros, which includes an appearance on Sunday Night Baseball this weekend.

Dominguez, 20, will be joined on the big league roster by 24-year-old catching prospect Austin Wells, sources confirmed to ESPN's Jeff Passan. The moves were first reported by MLB.com.

Phillies slugger Bryce Harper has hit his 300th career home run, going deep Wednesday against the Los Angeles Angels to become the 158th player in major league history to reach that mark.

Harper hit the milestone homer against Matt Moore in the eighth inning for his 15th homer of the season. The two-run drive, in Harper's 1,481st game, put Philadelphia ahead 8-7. The Angels rallied for three runs in the ninth, however, en route to a 10-8 victory.

The New York Yankees have placed Harrison Bader on waivers.

The Yankees acquired Bader in a trade with the St. Louis Cardinals last summer.

Bader has landed on the injured list twice this season. He's hitting .239/.275/.365 with seven home runs and 16 stolen bases in 306 plate appearances.

The Chicago White Sox have placed Mike Clevinger on waivers, according to a report.

Clevinger, 32, is playing under a one-year, $12 million contract. However, the structure of the deal leaves quite a bit left to be paid. He has about $1.42 million left in salary to be paid along with a $4 million buyout on a $12 million mutual option for the 2024 campaign. 

A 2.9 WAR player in 2023, he's posted a 3.32 ERA and 85 strikeouts over 97 2/3 innings.
