Shane Greene, 32 in November, has been a key reliever for the Atlanta Braves in their postseason teams in the past two seasons.
Between the Tigers and the Braves since the beginning of 2019, he has pitched to a 2.39 ERA (199 ERA+) in 93 games with 23 saves (22 of them coming before the Tigers traded him to Atlanta before the trade deadline in 2019).
He has a FIP of 3.79, a WHIP of 1.041, and a strikeout-to-walk ratio that is better than 3:1.
Liam Hendriks has been one of the best relievers in all of baseball for the Oakland A’s since 2019.
Since 2019, Hendriks, 32 in February, Hendriks has appeared in 99 regular-season games with 39 saves and an ERA of 1.79 (237 ERA+). His FIP is even better at 1.70 and his WHIP has been a spectacular 0.897.
He also has only walked 2 batters per nine innings compared to more than 13 strikeouts. In 2020, that number was even better as he walked only 1.1 batters per nine innings (three walks total) compared to 13.1 strikeouts per nine innings (37 total).
In 2019, he was an All-Star too. This is one of a few guys that would be great to have in the Rockies bullpen but his price tag may be too high for the Rockies liking.
