Greg Holland was 24 when he made his major-league debut for the Kansas City Royals on Aug. 2, 2010, vs. the Oakland Athletics. He arrived to the big leagues with a 96-98 mph fastball and a wicked slider. And a lot to learn.
Steve Foster was his bullpen coach, his teacher and his confidant.
Now, at age 31, after two all-star seasons, 145 saves and a sparkling 2.42 career ERA, Holland is trying to regain his form and effectiveness after undergoing Tommy John surgery in 2015. He’ll attempt to do so wearing a Rockies jersey at the toughest pitcher’s park in baseball, Coors Field.
