Andre Jackson pitched two-hit ball into the sixth inning in his first major league win, and the Pittsburgh Pirates beat the Kansas City Royals 4-1 on Wednesday night for a three-game sweep.

Jackson (1-1) struck out a career-high seven and walked two in 5 2/3 innings. The 27-year-old right-hander, who made his big league debut in 2021 with the Los Angeles Dodgers, allowed one run in his 20th major league appearance.

Bryan Reynolds and Jack Suwinski homered for the Pirates (61-73), and Vinny Capra hit an RBI double.

It was the first sweep for Pittsburgh since June 27-29 versus San Diego. The Pirates limited the Royals to four runs and 12 hits in the series.

Kansas City was swept for the 12th time this year. The Royals (41-94) have dropped six in a row and are on pace for 113 losses, which would break the club record of 106.

Bobby Witt Jr. hit his 27th homer for Kansas City. Witt, who has 38 steals, is trying to become the first player in franchise history to finish with at least 30 homers and 30 steals in the same season.

Royals left-hander Angel Zerpa (1-3) gave up three runs and five hits in 5 2/3 innings.

After Jackson departed, Ryan Borucki, Thomas Hatch, Colin Holderman and David Bednar combined for 3 1/3 innings of two-hit ball. Bednar worked the ninth for his 29th save.

The Pirates jumped in front when Reynolds launched a 436-foot drive to left-center in the first inning. It was his 19th homer this season.

Pittsburgh scored two more in the second. Capra drove in Liover Peguero with a double for his first career extra-base hit and RBI. Suwinski added a run-scoring single.

Witt responded with a leadoff shot in the fourth. He also drove a pitch to the wall in right-center with a runner on in the sixth, but Suwinski chased it down.

Suwinski connected in the seventh for his first homer since July 24 and No. 22 on the year.
