Colorado Rockies: Exploring trading away Jon Gray

Some other fits for the Rockies could be:
Center-fielder Starling Marte: 2018 stats: 145 games, 20 HRs, 72 RBI, 32 doubles, 33 stolen bases, .277/.327/.460, 114 OPS+, 50 DRS in the past 4 seasons (9 DRS since 2017). Contractually, he is owed $10.33 million this season and there are 2 team options for 2020 and 2021 for $11.5 million and $12.5 million. There are also buyouts for a combined $3 million.
Left-fielder Corey Dickerson: The former Rockie played in 135 games in 2018 with 151 hits, 35 doubles, 13 HRs, 53 RBI, .300/.330/.474 slash line, 119 OPS+, 16 DRS (which was enough to get him a Gold Glove for this season). He is projected to make $8.4 million in 2019, his final year before free agency.
Also, two of their relievers might pique the Rockies interest.
Left-handed reliever Felipe Vazquez (formerly Rivero): 2018 All-Star, 2.70 ERA in 70 games, 37 saves, 2.43 FIP, 3.1 BB/9, 11.4 K/9, average fastball velocity of 98.6 MPH. In 2017, he pitched in 73 games with a 1.67 ERA and 21 saves. He is owed $18 million over the next three seasons. He also has 2 team options for $10 million a piece for 2022 and 2023 with a combined $1.5 million in buyouts.
Right-handed reliever Keone Kela: 3.29 ERA in 54 games with 24 saves in 2018 (split between Texas and Pittsburgh). 2.97 FIP, 3.3 BB/9, 11.4 K/9. He has one more year of arbitration after this offseason, where he is projected to make $3.2 million.
