8. Alex Colome
Alex Colome was acquired as an International Free Agent in 2007 out of the Dominican. He’s currently 31-years-old and had been with the Rays for eight seasons prior to this ranking. The Rays clearly showed more patience with Colome than they did with Adrian Rondon.
At the time of this ranking, Colome was entering his age-26 season. He had proven himself in the minor leagues at this point and already made his major league debut in 2013 with the Rays.
The projection for Colome already had him pegged as a late-inning reliever or potentially a setup guy. That was pretty close, but he’d take it a step farther.
Colome is one of the few prospects that warranted the top-ten ranking. He’s one of the few on this list that has worked out.
He was already coming off of a 2014 major league season in which he nailed down a 2.66 ERA in 23.2 innings in 2014.
He destroyed Triple-A hitting in Durham with a 1.64 ERA over 86 innings pitched.
It was evident that Alex Colome was ready to be unleashed on the big leagues.
The season following these rankings he would start 13 games with the Rays and appear in 43 total contests. He finished his first full season with an impressive 3.94 ERA and only walked 2.5 batters per nine frames.
The next year he made the All-Star team with a 1.91 ERA and logging 37 saves. He had found his role as a major league closer just one full season removed from being ranked the Rays’ number three prospect.
In 2017 he led the American League in saves with 47.
Colome is currently the closer for the White Sox, where he just finished up a 30-save season with a 2.80 ERA. He is set to make over $10 million in 2020.
