Arenado, who has won six straight Gold Glove Awards and four consecutive Silver Slugger Awards, made $17.85 million last year.
He hit .297 with an NL-high 38 home runs and 110 RBIs, which tied for second in the league, to help the Rockies reach the playoffs for the second straight season. They beat the Chicago Cubs in the wild-card game before being swept by the Milwaukee Brewers in the Division Series.
Colorado agreed to one-year contracts with All-Star shortstop Trevor Story, right-handers Jon Gray and Chad Bettis, left-hander Tyler Anderson, right-handed reliever Scott Oberg and catcher Tony Wolters to avoid arbitration.
Story, the Rockies' first-round pick in the 2011 amateur draft, gets a big raise from $630,000 to $5 million. He hit .291 with 37 homers and 108 RBIs in earning his first All-Star selection.
Anderson, also a first-round pick in the 2011 draft, received a salary of $2,625,000, a raise from $555,000. He was 7-9 with a 4.55 ERA.
Gray will earn $2,925,000, up from $550,000. The team's first-round pick in the 2013 amateur draft went 12-9 with a 5.21 ERA.
Bettis, who went 5-2 with a 5.01 ERA, will get $3,325,000, up from $2 million.
Wolters gets a raise from $550,000 to $960,000 after hitting .170 with three homers and 27 RBIs.
Oberg and the Rockies agreed to a $1.3 million deal. The 28-year-old pitcher made $555,000 in 2018 as he emerged as one of Colorado's more reliable relievers. He was 8-1 with a 2.45 ERA and 57 strikeouts over 58 2/3 innings.
Oberg appeared in all four of Colorado's postseason games last season, going 1-0 with a 4.91 ERA.
