Nova, who turned 26 on Saturday, has an amazing ability to win even when he doesn't pitch well. He finished the season at 12-8, despite a 5.02 ERA. He also ended the year being lifted from the rotation.
In the first half of the season, he went 10-3 with 3.92 ERA, while in the second half he was just 2-5 with a 7.05 ERA. So, after averaging 14 wins in his first two full major league seasons as a starter, Nova is not guaranteed a spot in his third year.
Phelps, also 26, had a nice rookie year, finishing 4-4 with a 3.35 ERA. As a starter, he was 2-2 with a 3.77 ERA in 11 starts. He showed some nice potential, but it is still a very small sample size.
QUESTION: Who do you think should win the No. 5 starter spot?
