Arizona appears to have the more familiar group against the opposing starter, with six hitters owning prior plate appearances against May compared with six for St. Louis but a larger sample at the top of the order. St. Louis does have the sharper standout matchup in Nootbaar, but more of its lineup is seeing Pfaadt for the first time.
