Jeffress came to the Royals from the Milwaukee Brewers via the Zack Greinke deal. He has struggled throughout his career with his command.
He admitted that he made progress this season with the help of minor league pitching coaches Doug Henry and Larry (LC) Carter:
”In the last year, I felt like I made progress,” Jeffress said. “The first time I came up in April at the beginning of the year, it really opened my eyes. I felt like I had to learn a lot more stuff off the field and to be able to stay focused on my task at hand. The year before, 2011, I just felt like I was all off. It was my first year breaking camp with the big team and when I got sent down, my concentration was just all lost.”
He is expected to head to play winter ball for Bravos de Margarita in Venezuela. The Blue Jays need bullpen help and Jeffress could be a key cog if he can figure it all out.
