If not for injuries, Jimmy Nelson would probably be the ace of the Milwaukee Brewers but, alas, they non-tendered him.
He only made 10 appearances in 2019 and he completely missed the 2018 season due to arm injuries. In 2017, he came in 9th in the NL Cy Young voting as he went 12-6 with a 3.49 ERA (3.05 FIP) in 29 starts. He also had a better than 4:1 strikeout-to-walk ratio with striking out 199 batters and walking only 48 in 175 1/3 innings.
He was projected to make $3.5 million in arbitration so an incentive-laden, short-term contract could be good for the Rockies and for Nelson to go back on the open market in the near future and prove that he’s healthy.
Between 2018 and 2019, Yimi Garcia allowed 22 homers in 84 2/3 innings but he struck out more than a batter per inning and averaged less than two walks per nine innings.
In 2019, he allowed only 40 hits (5.8 per nine innings) but 37.5 percent of those hits were home runs, which is something that might not fare well at Coors Field.
However, his 2019 ERA was 3.61 so he mainly gave up runs on the long ball.
Considering that he was only projected to make $1.1 million in arbitration, he would be a cheap option if the Rockies want to take a flyer on him.
