Right-hander Trevor Bauer, third baseman Nolan Arenado, outfielder Charlie Blackmon and infielder-outfielder Jurickson Profar declined to opt out of their contracts to become free agents.

Bauer agreed to a $102 million, three-year deal with the Los Angeles Dodgers in February and began 8-5 with a 2.59 ERA in 17 starts. He has been on paid leave since July 2 while he is investigated under Major League Baseball's domestic violence policy. He is keeping salaries of $32 million in each of the next two seasons.

Elsewhere, the New York Mets announced Saturday they have extended $18.4 million qualifying offers to outfielder Michael Conforto and pitcher Noah Syndergaard -- a day ahead of Sunday's deadline. Players have 10 days to decide whether to accept the one-year offer.

Arenado was owed $214 million over seven seasons as part of the contract that was amended when he was traded Feb. 1 to the St. Louis Cardinals by Colorado. He had the right to opt out after this season and also has the right to opt out after the 2022 season. Arenado hit .255 with 34 homers and 105 RBIs in his first season with the Cardinals.

Blackmon struck a $108 million, six-year deal with the Colorado Rockies in April 2018 that included a $21 million player option for 2022 and a $10 million option for 2023. He kept his contract for 2022 after hitting .270 with 13 homers and 78 RBIs.

Profar agreed in January to a $21 million, three-year contract with the San Diego Padres and had the right to opt out of a deal that included $6.5 million for 2022, $7.5 million for 2023 and a $10 million mutual option for 2024. He hit .227 with four homers and 33 RBIs for the disappointing Padres.

Gold Glove catcher Tucker Barnhart's $7.75 million option was exercised Saturday by the Detroit Tigers, who acquired him on Wednesday for infield prospect Nick Quintana. Barnhart's option price included a $250,000 escalator for winning a 2020 Gold Glove and would go up again by the same amount if he wins for 2021.

The Chicago White Sox declined a $6 million option on 31-year-old infielder Cesar Hernandez. He hit .232 with 21 homers and 62 RBIs for Cleveland and Chicago, which obtained him on July 29.

Cincinnati Reds left-hander Justin Wilson exercised a $2.3 million player option, part of a $5.15 million, two-year deal he signed with the Yankees. By exercising the player option, Wilson gave the Reds a club option for 2023 at $500,000 above that year's minimum salary. He had a 2.81 ERA in 21 games after the Reds obtained him on July 28.

Josh Tomlin's $1.25 million option was declined by the World Series champion Atlanta Braves, who must pay a $250,000 buyout. The 37-year-old right-hander was 4-0 with a 6.57 ERA but did not pitch in the postseason.

St. Louis declined a $17 million option on right-hander Carlos Martinez, who gets a $500,000 buyout, and a $12 million option on infielder Matt Carpenter, who receives a $2 million buyout. Martinez was 4-9 with a 6.23 ERA, completing a $51 million, five-year contract. Carpenter hit .169 with three homers and 21 RBIs, finishing a $39 million, two-year contract.
