Rounding out the list are a pair of relievers in Comer and Montgomery.
Kevin Comer was a first-round pick of the Toronto Blue Jays in 2011, but made his way to the Houston Astros organization in the blockbuster that saw nine other players change teams.
A former starting pitcher, Comer made the switch to the bullpen full time last season and turned in some encouraging results.
In 63.2 frames for Houston’s Triple-A affiliate, the 25-year-old struck out 10.46 batters per nine innings to go along with a 72.8% strand rate, a 3.68 ERA, a 3.78 FIP and a 4.20 xFIP.
Another right-handed pitcher, Montgomery was actually Huffman’s teammate with St. Louis’ Triple-A team in 2017.
The reliever was also effective in recording outs in his 66.2 frames.
Over that span, the 27-year-old struck out 9.86 batters per nine innings while surrendering just 2.03 walks and 0.54 home runs per nine frames.
He registered a 2.43 ERA, a 3.30 FIP and a 4.18 FIP.
Prior to his 2017 season with St. Louis’ Triple-A squad in Memphis, Montgomery had spent his entire minor league career in the New York Yankees’ minor league system.
