CHICAGO (AP) — Kyle Schwarber and Albert Almora Jr. became free agents Wednesday when the Chicago Cubs declined to offer contracts to two key players from their historic 2016 World Series championship.

While Schwarber, Almora, slugger Jose Martinez and pitcher Ryan Tepera were non-tendered, the Cubs offered 2021 contracts to infielders Kris Bryant and Javier B·ez, catchers Willson Contreras and Victor Caratini, and outfielder Ian Happ. They agreed to one-year deals with relievers Kyle Ryan ($800,000 in majors, $250,000 in minors), Colin Rea ($702,500) and Dan Winkler ($900,000), avoiding arbitration with all three.

Chicago also announced it had claimed reliever Robert Stock off waivers from the Boston Red Sox. The 31-year-old right-hander was designated for assignment last week.

Wednesday’s non-tender deadline was the first major look at the state of the Cubs since Jed Hoyer was promoted to president of baseball operations last month, replacing Theo Epstein. While the Cubs held onto All-Star sluggers Bryant, B·ez, and Contreras, those players could still be on the move this winter via trade if the club looks to cut more payroll.

Schwarber quickly became a fan favorite in Chicago upon arrival, flashing tape-measure power at the plate. He also played in the 2016 World Series after missing most of the season with a left knee injury. The slugger served as the designated hitter for the games in Cleveland and hit .412 (7 for 17) with two RBIs as the Cubs won their first championship since 1908.

Almora made a key play in Game 7 against Cleveland, running for Schwarber in the 10th inning and advancing to second on Bryant’s fly ball to center. Almora then scored the go-ahead run on Ben Zobrist’s double in the Cubs’ 8-7 victory over the Indians.

Almora was selected by Chicago with the No. 6 overall pick in the 2012 amateur draft, and Schwarber went fourth overall in 2014. While Almora has struggled at the plate, Schwarber’s lefty power bat could attract significant interest on the open market — especially at designated hitter — despite his shortcomings in left field.

The 27-year-old Schwarber, a converted catcher, stumbled during the pandemic-shortened season, batting .188 with 11 homers in 59 games for the NL Central champions. But he set career highs with 38 homers, 92 RBIs and a .250 batting average in 155 games in 2019.

Almora, 26, is a solid defender in center field and a .271 hitter in 489 career games. But he batted just .167 in 28 games last season.

Winkler can earn $600,000 in bonuses for games pitched: $50,000 each for 40 and 45, $75,000 apiece for 50 and 55, $100,000 each for 60 and 65 and $150,000 for 70.

Ryan can earn $200,000 in bonuses for games pitched: $25,000 each for 40 and 45, and $50,000 apiece for 50, 55 and 60.
