All five home runs came on fastballs, and all were center-cut.
Josh Bell spotted Archer (3-6) an early lead by driving in a pair on a base hit in the first, but Atlanta went deep four times in the second. Josh Donaldson and Nick Markakis went back-to-back to start the inning, and after an Austin Riley strikeout, Brian McCann and Ozzie Albies hit consecutive home runs again.
In the process, Archer became the first Pirate pitcher ever to surrender four home runs in one inning.
