Who Is the Real Mike Montgomery?
Every year, a number of starting pitchers seemingly come out of nowhere to become significant contributors at the major-league level. Sometimes, like in the case of, say, Jacob deGrom, the sudden evolution at the major-league level is real and sustainable. In the case of the majority of these short-term success stories, the league adjusts, the pitcher is unable to, and either disappears from the major-league scene or settles into a lesser role.
This spring, Mariners right-hander Erasmo Ramirez was out of options, and was designated for assignment off of the 40-man roster. In these types of situations, a club is lucky to receive a fringe prospect in return. In this case, however, the Mariners were able to acquire the Rays’ version of Ramirez in lefty Mike Montgomery. His services were required at the major-league level shortly thereafter, and in his first seven starts, Montgomery was a revelation, posting a 1.62 ERA. In his last seven starts, however, he’s been more like the Book of Revelation, unfurling a 7.99 ERA. Which is the real Mike Montgomery, and might he still be someone the Mariners can be excited about moving forward? Is there really that a stark a difference between the Before and the After Model in this comparison test? Let’s take a look at Montgomery’s 2015 batted-ball data and make some observations.
