BOSTON -- On another hot and humid night at Fenway Park, which featured two hours and 21 minutes of rain delays, Salvador Perez found a way to break out of his recent slump.

The 31-year-old catcher, who’s in line to make his sixth All-Star Game start, went 4-for-4 with a home run and three infield singles in a 6-2 loss to the Red Sox on Wednesday night.

“Yeah, that’s doing it in a big way, I mean giving us a lead early,” manager Mike Matheny said. “Four hits, that’s hard to do. Especially coming off a day where you’re not seeing the ball well. So that gave us a good jolt.”

Entering the game, Perez was 3-for-31 in his last eight games, with his slump starting in the series after the Royals’ last meeting with the Sox in Kansas City. His second-inning homer opened the scoring and marked his first blast in his last 40 at-bats.

In the first two games of the series, Perez recorded just one hit (a seventh-inning single on Monday) and struck out six times.

Perez followed his solo shot on Wednesday with a single in the fourth, then another single in the sixth. Perez’s fourth-inning single came off the bat with the force of an extra-base hit, but it was stopped by Red Sox second baseman Marwin Gonzalez to limit Perez to a single.

A rainstorm did its best to slow Perez’s roll, delaying the game for one hour and 50 minutes before the bottom of the fifth. After play resumed at 10:35 p.m. CT, Perez stepped up in the ninth inning and hit his third infield single of the night. The single sealed Perez’s perfect night at the plate and marked the fifth game this season in which he has recorded three or more hits, tying Whit Merrifield for the most such games by a Royal.

Wednesday’s offensive performance was a welcome sign for Perez, who was batting .292 with a .540 slugging percentage prior to his slump. Despite his recent struggles at the plate, Perez leads American League catchers with 61 percent of the total votes in the latest All-Star Game voting tally update.

With Perez heating up to end the month, the Royals hope to follow his lead after going 7-20 (.259) in June, marking their lowest winning percentage in a month since June 2018 (5-21, .192). They’ll look to get back on track and avoid the sweep in Thursday’s 12:10 p.m. CT finale with Kris Bubic on the mound to face Boston’s Nathan Eovaldi.

“I feel like we should just keep rolling, keep doing our thing,” said starter Mike Minor, who gave up five runs on seven hits and two walks over five innings on Wednesday. “Obviously right now it’s not working, but [hopefully] we can change. A couple of the guys are making good at-bats up there, guys are competing on the mound, doing everything they can. … Sometimes you just run into good teams, and right now, they’re hot.”
