DETROIT -- The prospect is producing.

Jackson Chourio’s go-ahead, two-run double in the sixth inning was the difference maker in Saturday afternoon’s 5-4 victory over the Tigers at Comerica Park, clinching the series win ahead of Sunday’s finale.

While the rookie outfielder entered the game with a modest .209 batting average to go with six homers and 19 RBIs, he’s showing signs of perhaps becoming the star he’s expected to become. Chourio, 20, entered this season as the No. 2 prospect in the game, per MLB Pipeline.

“If you’ve watched Jackson in the last month, he hasn’t gotten to play every day but he’s helped us win a bunch of times, and today was no exception,” said Brewers manager Pat Murphy. “A huge hit at a huge time, and with two outs.”

Chourio had exactly one homer and three RBIs between April 21 and June 1 -- what changed for him?

“I mean, he has a better approach at the plate,” said Murphy. “I think he’s got a little confidence. He doesn’t feel the pressure that he felt early, and he’s swinging at strikes. He’s got a great swing when he swings at strikes.”

Chourio, who is signed to an eight-year, $82 million deal, beat out an infield single in the third inning before coming around to score on a sac fly by Christian Yelich, who went 2-for-4 with a pair of RBIs.

Milwaukee starter Freddy Peralta gave up four runs (three earned) in 3 1/3 innings, but Jared Koenig then began a parade of successful relief appearances. He blanked the Tigers for 1 2/3 hitless innings, earning the win and improving his record to 6-1.

Koenig, Enoli Paredes, Bryan Hudson, Joel Payamps and Trevor Megill made Chourio’s go-ahead double stand up for the win. In all, the Brewers’ bullpen allowed just one hit and zero walks over 5 2/3 scoreless innings.

Murphy was asked about deciding against pinch-hitting for the right-handed hitting Chourio against Tigers right-handed reliever Shelby Miller in the sixth.

“It was because you are trying to nurture this kid into, ‘We believe in you,’” Murphy said. “But you’ve got to keep doing the things that keep you on the field. Use your talents. And you’ve got to know baseball. So, you can’t go up there free-swinging. Go up there understanding what you’re looking for.

“Inside, that’s my little victory in my mind.”

“I’m just very grateful he has the confidence in me,” Chourio said through interpreter Daniel Demondesert. “All I’m trying to do is go out there and win [Murphy’s] confidence. So, thanks to God, things were able to go our way there. That’s an at-bat I’m trying to prepare myself for, and things went our way.

“I was just thinking it was time for me to put my foot in the ring, and help the team win a game. So, I was just waiting for this moment.”

Possibly entering into Murphy’s decision was the fact that Miller has reverse-splits this season. Entering Saturday, lefties were batting just .097 against him with zero home runs in 31 at-bats. Righties, meanwhile, were hitting .242 with two homers in 33 at-bats.

“He’s got to relax and swing at strikes,” said Murphy. “It’s something he’s got to get used to. He’s got to go through it, and he’s got to understand, ‘I’ve got to practice this. I’ve got to take balls and swing at strikes.’ And he gets the message most when he doesn’t see his name in the lineup.”

Chourio said his approach was simply a matter of showing patience and looking for a good pitch to hit.

“At the beginning of the season there was a different mentality there,” Chourio said. “But now that we’re getting into it, I’m just trying to focus on playing my game and slowing the game down. Doing that has allowed me to just take it at-bat by at-bat, and again slow the game down and play it the way I want to.”

Did being rated so highly entering the season weigh on him?

“That’s not something I ever really think about,” said Chourio. “All I’m trying to do is go out there and give the best version of myself on the field, and I don’t pay too much mind about whether I’m a prospect or not. I’m just trying to go out and play the game hard.”
