J.P. Crawford had the highest Win Probability Added on the Mariners yesterday. If WPA measured defensive plays, it might not be so, since he had a wayward throw that started Justin Dunn’s fourth inning off quite poorly, but the M’s leadoff man made up for it with a couple other nice bits of glovework and a whole lot of excellence at the plate. 2-for-3 with a pair of walks looks nice enough, but by far his most notable plate appearance was his last - facing lefty specialist Ryan Buchter in the top of the 8th.
