When talking about a lights-out closer, Alex Colomé is one of them. If he has not reached that status yet is oh so very close to it. In 61 innings, Colomé held a 2.80 ERA while saving 30 games. As someone who has saved 47 games in a season before (2017 for the Rays), with the right team, Colomé can certainly save at least 35 games in 2020.
After six okay years with Tampa Bay he was traded at the 2018 deadline and finished as strong as ever with the Mariners. In 46.1 innings with Seattle, Colomé struck out 49 and held an ERA of 2.53. He was basically lights out the second half. This drew the interest of the White Sox. An emerging star of a closer who just started his prime was obtainable so they pulled the trigger and got him.
But the team runs into one problem which his contract. His contract ends at the end of the season. If the team has Colomé in their contending plans, it might be wise to work out an extension before the season starts and his stock rises. If the team believes they will not fall apart without him in 2021 and beyond, there are a few names that have shown signs to take over the closing role.
