Before taking on the White Sox at Guaranteed Rate Field on Saturday night, the Red Sox recalled right-handed pitching prospect Connor Seabold from Triple-A Worcester.

In a corresponding move, fellow right-hander Brad Peacock was returned to Worcester to make room for Seabold on the active roster, the club announced earlier Saturday afternoon.

Seabold, 25, is regarded by Baseball America as the No. 12 prospect in Boston’s farm system, ranking sixth among pitchers in the organization.

The right-hander will make his major-league debut and first career start in Saturday’s contest against the White Sox, as he was one of four players who traveled with the Red Sox to Chicago as part of the team’s taxi squad.

Nick Pivetta was originally in line to get the start on Saturday, but has since had to be scratched from that outing on account of testing positive for COVID-19 last week.

That being said, Pivetta will be able to make his return to the mound and start in place of Chris Sale, who also recently tested positive for coronavirus, in the finale of this three-game weekend series on Sunday.

While Pivetta will take over for Sale on Sunday, Seabold will essentially take over for Pivetta on Sunday.

The Red Sox originally acquired Seabold and Pivetta from the Phillies in a trade that sent relievers Brandon Workman and Heath Hembree to the Phillies last August.

The 25-year-old was added to Boston’s 40-man roster in November in order to receive protection from the Rule 5 Draft and was also invited to major-league camp earlier this spring, but had the start of his 2021 season pushed back by approximately 2 1/2 months due to right elbow inflammation.

After a brief rehab assignment in the Florida Complex League, Seabold made his debut for Worcester on July 23. He has posted a 3.67 ERA and 4.17 FIP to go along with 44 strikeouts to 13 walks over eight starts spanning 41 2/3 innings of work for the WooSox since then.

Listed at 6-foot-3 and 195 pounds, the California-born righty operates with a three-pitch mix that consists of a 91-93 mph fastball that tops out at 95 mph, a deceptive 80-82 mph changeup, and an 83-85 mph slider, per his SoxProspects.com scouting report.

Considering the fact that his most recent start for the WooSox came on September 4, it’s safe to assume that Seabold — who will be wearing the No. 67 — will be plenty stretched out for his big-league debut later Saturday night.

With the addition of Seabold to the major-league roster, the Red Sox returned a veteran in the form of Peacock to Worcester.

Boston picked up the 32-year-old in exchange for cash considerations in a minor trade made with the Indians late last month.

Peacock appeared in two games for the Sox, making his first start for the club in their bout against the Rays on August 31 and being used out of the bullpen exactly one week later.

As he makes his way to Worcester, Peacock will look to provide the Red Sox with experienced starting rotation and bullpen depth for the final few weeks of the regular season.

Prior to getting traded, Peacock put up a 7.68 ERA and 5.16 xFIP in addition to 38 strikeouts and 14 walks over 11 appearances (10 starts) and 34 innings pitched with Triple-A Columbus after signing a minor-league pact with Cleveland in June.
