The Mariners’ Tom Murphy Is Making The Most Of It
Less than a year ago, Tom Murphy was catching in Triple-A Albuquerque, batting eighth for the Isotopes and wrapping up a fourth consecutive season in which he failed to register 100 big-league plate appearances. Now platooning with Omar Narvaez in Seattle, Murphy’s .366 wOBA is sixth among big-league catchers with as many trips to the plate, and he has past the century mark on that count two weeks before the 4th of July. Since June 1, he’s hit five home runs for the Mariners, matching his career high for a single season in a month that’s not over yet.
To hear Murphy tell it, his sustained success in the major leagues this year — he’s always been a good Triple-A hitter — has been driven by three major adjustments, made meaningful by the opportunity he’s getting to play so often. The first is to the pitches he’s hunting. The second is to the way his upper body helps him get to those pitches in time to make contact. The final adjustment is to the physical foundation that lets him do damage when he makes contact.
During his first four seasons in the big leagues, Murphy swung at 74% of the fastballs he saw up in the zone (64 of 86), which was about the same rate at which he swung at fastballs in the middle and bottom thirds, too. (He swung at 70% of those pitches, or 116 of 165 he saw.) This year, by contrast, he’s swinging at pitches in the top third nearly 81% of the time (34 of 42 pitches), and pitches in the bottom two-thirds just 64% of the time (63 of 99). That’s the first adjustment.
But just swinging at different pitches won’t make much of a difference if you can’t hit those pitches when you try to. Murphy told me that this off-season, he switched from taking pitches off a tee to training off an Iron Mike pitching machine almost exclusively. The resultant change in training velocity — from literally zero to something more closely approximating game speed — exposed what, to Murphy, had become an unhelpful amount of “slack” in his upper body.
