The deals mean the Rockies have avoided having to go to an arbitration hearing with any of their players. Earlier on Friday, the Rockies announced a two-year contract worth $29.5 million with third baseman Nolan Arenado. Friday was the deadline for teams and players to exchange their filing numbers.

Earlier in the offseason, the Rockies avoided arbitration by reaching one-year agreements with left-hander Jake McGee for $5.9 million and right-hander Jordan Lyles for $3.18 million.
Blackmon, 30, the Rockies' leadoff hitter, established career bests in runs (111, third in the National League), hits (187), doubles (35), home runs (29), RBIs (82), batting average (.324, fourth in the NL), on-base percentage (.381) and slugging percentage (.552) during a breakout season in 2016. His homers led all leadoff hitters in the Majors.
After missing the better part of two seasons because of Tommy John surgery on his right elbow, Chatwood, 27, returned in 2016 and went 12-9 with a 3.87 ERA, with 117 strikeouts against 70 walks in 158 innings. On the road, he went 8-1 with a 1.69 ERA -- a franchise record-low, and best in the Majors for a starter who logged as many road innings as his 80.
