If ever there were a tale of two halves, it was Flaherty's 2019 season. A 4.64 ERA with a 1.23 WHIP in the first half, followed by a preposterous 0.91 ERA and 0.71 WHIP in the second half. His strikeout rate jumped, his walk rate dropped, and he saw a gain of almost a mile per hour on his fastball. The real Flaherty likely lies somewhere in between his first and second halves, but that should be a top-10 pitcher in 2020.
