MILWAUKEE (AP) — Free-agent outfielder Jackie Bradley Jr. is joining the Milwaukee Brewers, agreeing to the parameters of a $24 million, two-year contract, a person familiar with the negotiations told The Associated Press.

The person spoke on condition of anonymity Thursday because the details of the agreement were still being negotiated and the deal is subject to a successful physical.

Bradley would have the right to opt out after one year and $13 million, allowing him to become a free agent after this season.

The Boston Globe first reported Bradley’s decision,

Bradley will join the Brewers well into spring training, which started in mid-February. Opening day is April 1.

Bradley turns 31 on April 19 and is regarded as a top defensive center fielder. He had spent his entire career in Boston and batted .283 with seven homers and 22 RBIs during the pandemic-shortened 2020 season. He had a .364 on-base percentage and an .814 OPS in 55 games last season.

Bradley earned $4,074,074 in prorated pay from an $11 million salary.

His career numbers include a .239 batting average, .321 on-base percentage. 732 OPS, 98 homers and 376 RBIs. He won a Gold Glove in 2018 and led the American League in assists by a center fielder in 2014, 2016, 2018 and 2019.

This move continues the Brewers’ offseason emphasis on defense.

The Brewers already added former St. Louis Cardinals second baseman Kolten Wong, a Gold Glove winner each of the last two seasons. Wong signed a two-year, $18 million contract with a 2022 team option after the Cardinals declined to pick up their $12.5 million option on him.

Bradley’s addition seemingly gives the Brewers four potential starters for three outfield spots.

The Brewers already have 2019 Gold Glove center fielder Lorenzo Cain, who opted out after playing five games last season but is back in spring training camp.

“We’re trying to get his legs underneath him and it’s going a little slower than we’d like,” manager Craig Counsell said.

Christian Yelich, the 2018 NL MVP, is set in left field.

Milwaukee also brings back Avisail Garcia, who usually has played right field but took over in center last year after Cain’s exit. Garcia batted .238 with a .659 OPS in 53 games last season but had a .796 OPS with 20 homers two years ago with Tampa Bay.

Without commenting specifically on the potential addition of Bradley, Counsell noted how depth could boost Milwaukee’s outfield.

“Adding players that we can put out there every day, a combination of players who are going to tackle all of those plate appearances, I think it can create a really good insurance floor,” Counsell said.

Since the NL is expected to go without a designated hitter this season, the Brewers would seem to have a surplus of outfielders accustomed to starting, unless they make another move in the next few weeks.

“We don’t have any fourth outfielders,” Counsell said. “We’re going to have a lot of starting outfielders and we’re going to have to figure out how that works. That’s kind of how I’m viewing it. But there is playing time, absolutely.”
