BOSTON — Shortstop Xander Bogaerts and outfielder Jackie Bradley Jr. were among nine Boston Red Sox players who reached deals on one-year contracts Friday with the AL East champions, but All-Star outfielder Mookie Betts is headed to arbitration after he and the team couldn’t agree on a contract.

Pitchers Joe Kelly, Drew Pomeranz, Eduardo Rodriguez and Brandon Workman, infielder Brock Holt and catchers Sandy Leon and Christian Vazquez also settled.

At 25, Betts dipped from his 2016 success, when he led the league in total bases and was the runner-up in AL MVP voting. His average fell from .318 to a career-low .264, and he had 24 homers with 102 RBI, down from 31 homers and 112 RBI. He finished sixth in the MVP voting.

According to reports, Betts is asking for $10.5 million in arbitration, while the Red Sox are offering $7.5 million.

Bogaerts will make $7.05 million, up from $4.5 million last season. The 25-year-old hit .273 with 62 RBI and 15 steals.

A year after becoming an All-Star, Bogaerts saw his power drop from 21 homers to 10. His second half was the problem: He batted .229 with a .339 slugging percentage after June 22.

Bradley will get $6.1 million, an increase from $3.6 million last year, when he hit .245 with 17 homers and 63 RBI.

Although he remained a defensive star, the 27-year-old Bradley had a falloff from his All-Star season in 2016, when he batted .267 with 26 homers and 87 RBI. The Red Sox reportedly turned down an offer from the Los Angeles Dodgers this offseason to trade him straight up for Yasiel Puig.

Pomeranz gets $8.5 million, a raise from his $4.45 million last year. The 29-year-old lefty went 17-6 with a 3.32 ERA in his first full season with Boston.

After struggling in Boston in 2016, a season in which he made the NL All-Star team with San Diego before being traded to the Red Sox, Pomeranz tied Chris Sale for the team lead in wins. But in the AL Division Series against Houston – his first career postseason start – he allowed four runs while lasting just two innings.

THIRD BASEMAN Josh Donaldson and Kris Bryant set records when they were among 145 players who agreed to one-year contracts rather than swap proposed salaries in arbitration with their teams.

Donaldson and Toronto agreed at $23 million, the largest one-year deal for an arbitration-eligible player. The 32-year-old, a three-time All-Star, topped the $21,625,000, one-year deal for 2018 agreed to last May by outfielder Bryce Harper and the Washington Nationals.

Donaldson, the 2015 AL MVP, got a $6 million raise after rebounding from an injury-slowed 2016 to hit .270 last season with 33 homers and 78 RBI in 113 games.

Bryant settled with the Chicago Cubs at $10.85 million, the most for a player eligible for arbitration for the first time. The previous mark was held by Philadelphia first baseman Ryan Howard, who was awarded $10 million in 2008.

Bryant hit .295 with 29 home runs and 73 RBI last year, when he made $1.05 million. The previous season, he earned National League MVP honors when he hit .292 with 39 homers and 102 RBI.

YANKEES: New York reached one-year contracts with its remaining six players eligible for arbitration, leaving its projected payroll at $177 million – $20 million below the luxury tax threshold.

Shortstop Didi Gregorius agreed at $8.25 million, pitcher Sonny Gray at $6.5 million and setup man Dellin Betances at $5.1 million. Also reaching deals were relievers Adam Warren ($3,315,000) and Chasen Shreve ($825,000), and backup catcher Austin Romine ($1.1 million).

ORIOLES: Baltimore agreed to a $16 million contract with third baseman Manny Machado and a $12 million deal with injured closer Zach Britton.

ASTROS: Left-hander Dallas Keuchel agreed to a $13.2 million, one-year contract, and pitchers Lance McCullers Jr. and Brad Peacock and catcher Evan Gattis also reached one-year deals.

INDIANS: Cleveland avoided salary arbitration with starter Danny Salazar and right fielder Lonnie Chisenhall but didn’t settle with pitcher Trevor Bauer.

Salazar, who is coming off an inconsistent and injury-slowed 2017, will make $5 million. Chisenhall’s contract is worth $5.58 million.

Bauer’s representatives submitted a salary of $6.25 million for arbitration, while the Indians countered at $5.3 million.

ROCKIES: NL batting champion Charlie Blackmon avoided salary arbitration by agreeing to a $14 million, one-year contract.

The 31-year-old center fielder hit .331 with 37 homers and 104 RBI last year and made $7.3 million.

RAYS: Closer Alex Colome and All-Star designated hitter/outfielder Corey Dickerson were among seven players who agreed to one-year contracts with Tampa Bay.

Colome received a whopping raise from $547,900 to $5.3 million after going 2-3 with a 3.24 ERA and a major league-leading 47 saves in 2017.

Dickerson was bumped up to $5.95 million after batting .282 with a career-best 27 homers last season, when he made $3.025 million and was the starting designated hitter for the AL in the All-Star Game.
