PHOENIX – Barring completely unforeseen personnel moves, Ji-Man Choi has no real chance of making the Milwaukee Brewers’ opening day roster.

Nevertheless, the slugging first baseman from South Korea is making an impact in his first Brewers camp, on and off the field.

“He has been a pleasant surprise overall, for sure,” manager Craig Counsell said.

Choi, 26, was signed to a minor-league deal over the off-season mostly to give the Brewers an experienced first baseman at Class AAA Colorado Springs. He spent most of last season with the New York Yankees, Class AAA Scranton/Wilkes-Barre affiliate, batting .288 with 15 homers and 69 RBI in 87 games.

The Brewers are well-manned at first base, with holdovers Eric Thames and Jesús Aguilar (47 homers, 115 RBI between them in 2017) as well as Ryan Braun, who is being asked to play some first base to open left field for newcomer Christian Yelich.

But Choi has played as if determined to make the decision makers find a way to keep him.

Choi has lived up to his reputation as a power hitter, with two doubles, two homers and eight runs batted in over 23 at-bats, with an .870 slugging percentage heading into Tuesday’s game against the Texas Rangers. He was also batting .435 with a .563 on-base percentage.

Choi kept alive a winning three-run rally in the ninth inning Sunday in Cleveland by drawing an 11-pitch walk. On Monday, he sparked a 7-6 victory over the Los Angeles Dodgers with a grand slam after falling behind in the count, 0-2.

“I got down two strikes and was just trying to get a good at-bat together,” Choi said of his grand slam through translator Daniel Cho. “I wasn’t necessarily thinking home run, but I’m glad the result was good.”

Said Counsell: “Since the first day, he has done a nice job. He has put together tough at-bats the whole spring. Plate discipline is a strength; ball-strike discernment is a strength of his. And he has done that all spring.

“I think we thought that going in. I was expecting to see that really.”

Choi credits a small tweak suggested by hitting coach Darnell Coles with his latest hot streak. His average was at its lowest point in camp at .267 on March 3 when Choi incorporated it, and he’s been on a steady climb ever since.

“(Coles) made an adjustment in my stance, and after that adjustment I’ve felt more confident and more comfortable and had better results. The (grand slam) was a product of that,” Choi said.

“My (front) shoulder was going in a little bit. But it was a very slight thing that I didn’t even notice. But he noticed it and gave me that tip and I was able to adjust accordingly. If he hadn’t given me that tip, I’d still be in that little slump that I had.

“I’m really thankful to him.”

The 26-year-old Choi, who made his second start of the spring in left field on Tuesday, acknowledged this spring has been his the best of his young major-league career.

“I’m very locked in and confident,” he said. “I’m sure the experience helps and stuff like that comes into play, but it’s more so my teammates and coaching staff. I have such a great bond with them.

“I don’t need to think about playing time. I just need to do the best that I can. The team obviously comes first.”

Though needing Cho to hold detailed discussions in English, the expressive Choi also has made an impact in the Brewers’ tight-knit and fun-loving clubhouse. He has a smile on his face most of the time, finds time to greet as many teammates as possible and even joins in the dance parties that often break out in the music-filled environment.

“I’m enjoying my time here,” Choi said, with an assist from Cho. “I’m getting comfortable with my teammates. I really enjoy the atmosphere.

“It’s a special place for me. I feel like it’s a perfect fit for my personality. I wasn’t sure what to expect at first. I love the way everyone goes about things professionally but also has the balance to goof around and play around. I really like it here.”

As for his latest dance moves, Choi smiled and said, “I don’t even know what I was doing. It just came out.”
