Know your Rays: swinging at the fastball (Friday)

A very fun game.

Previous days: Monday (Ben Zobrist), Tuesday (Evan Longoria), Wednesday (Desmond Jennings)

Thursday: This Ray continues a pattern that you may recognize by now. Like Longoria and Jennings, this Ray likes to swing at high fastballs all across the zone from opposite-handed pitchers (while ignoring low fastballs from them), and from same-handed pitchers he's likely to swing at a fastball up and and in but to take a fastball down and away. Unlike Longoria and Jennings, this player is left-handed. This player is Matt Joyce.

Joyce's is quite successful. From FanGraphs, he's been 1.63 runs above average per 100 unclassified fastballs and four-seam fastballs (FA and FF by the MLBAM classifications), and 1.17 runs above average per 100 two-seam fastballs. He's the epitome of a fastball hitter.

Leading the tally for the week so far: Andy Hellicksonstine (3 of 4)

As with all of this week's puzzles, I've given you a graph from Jeff Zimmerman's Baseball Heat Maps, and you need to determine who's swing tendencies are being depicted.The two charts below show how often a Rays player swung at a fastball in different locations of the strike zone. They include all pitches classified by MLBAAM as FA, FF, and FT from 2007 through the present, and compare the player to league average. Green means that the player swung at a pitch in that location about as often as the league as a whole did. Blue and purple means that the player swung less often at a pitch in that location. Yellow and red means he swung more often.
