As our friends at @RockiesWX pointed out earlier in the day, storm conditions have been building all day. As first pitch time drew near, the Colorado Rockies announced that the game was in a weather delay.
This is similar to a game earlier in the week against the defending World Champion Houston Astros when lightning in the area caused the first pitch to be delayed. That game eventually started one hour late.
When Saturday night’s game gets underway, Brett Anderson (2-2, 5.46 ERA) is scheduled to take the hill for the A’s.
