Acquired by the Diamondbacks during their playoff run last season David Hernández was a quality reliever. Hernández had his second-lowest WHIP of his career with an elite 1.03 mark. His FIP was also the second lowest of his career at 2.76. Hernández also had a career-low BB/9 of 1.5. While he was at pitcher-friendly Angel Stadium for the majority of the season, he has shown that he can handle the daunting challenge of Chase Field. During his 2011-2013 seasons with the D-Backs Hernandez posted WHIP’s of 0.98, 0.83, and 0.88 at Chase Field. His past success at Chase Field would bode well at hitter-friendly Miller Park.
