Robbie Ray, LHP, Arizona Diamondbacks
Robbie Ray is another former All-Star who might be revitalized with a change of venue and he is also the youngest on this list at age 28 and a birthday not coming until Oct. 1.
Ray signed with the Arizona Diamondbacks this offseason for one year and $9.43 million and can become a free agent next winter.
But since setting the National League on its ear with a 2.89 ERA and 1.154 WHIP in 162 innings in 2017 while leading the league with a rate of 12.1 strikeouts per nine innings, Ray has taken some steps backward.
His strikeout rate has remained consistent, 12.0 per nine in 2018 and 12.1 per nine last season, but his other peripherals have not fared as well.
Last season in 33 starts, Ray had a 4.34 ERA and a 1.342 WHIP in 174.1 innings (matching a career-high), with 235 strikeouts and 84 walks while serving up 30 home runs.
That came after a 3.93 ERA and 1.350 WHIP in 123.2 innings over 24 starts in 2018.
Ray has the stuff to be a top-end guy in a rotation, if he can maintain his location and consistency, but after posting a walk rate of 3.7 per nine innings over 492.2 innings from 2014-17, he walked 5.1 per nine in 2018 and 4.3 last season.
Maybe working with new Angels pitching coach Mickey Calloway, who worked wonders with the Cleveland Indians from 2013-17, could help Ray regain his command of the strike zone.
