The written preview lands about a day and a half before the game, once the lineups, the injuries and the market have settled. Until then the boards below carry the matchup: recent form, how the two sides compare, and where each of them sits.
The full preview, matchup keys, probable starters and the storylines to watch, posts closer to game time, once lineups are set.
Where each side sits in its own division, with both clubs marked. These two are in different ones, so the tables are separate and the records are not directly comparable.

Colorado Rockies55-90.379L3Taken from each club's most recent lineup. The official cards post 2 to 3 hours before first pitch, so a name here can still be scratched, and the batting order is the likelier thing to move than the nine men in it.
