Last year, Trevor Rosenthal’s name definitely wouldn’t have been on this list as he was pitching so poorly. Between the Washington Nationals and Detroit Tigers, he had an ERA of 13.50 in 22 games. He had 26 walks and allowed 23 earned runs in just 15 1/3 innings.
But he has completely turned it around for the Kansas City Royals in 2020. He has been their closer in 2020 and in 11 appearances, he has an ERA of 0.87. That’s just one earned run in 10 1/3 innings with six saves. He’s got a WHIP of 0.871 and he has walked 3.5 batters per nine innings while striking out more than 12 in the same span.
The Royals signed him to a minor-league deal before Spring Training and since the contract only goes for the remainder of the season, the Rockies should be able to get him for a lower-level prospect that would likely be a player to be named later (since only players on a team’s 60-man pool are technically allowed to be traded as of now).
The Rockies could even look to acquire more than one reliever from the Royals since they are not going to be in contention. In fact, they could look to acquire someone that they know well.
