Goals from Oscar Threlkeld and Craig Tanner earned Plymouth a 2-0 win against Crawley and moved them to the top of Sky Bet League Two.
The Pilgrims dominated throughout but took until the 69th minute for Threlkeld to break the deadlock as he converted a driven cross from David Fox from 10 yards.
Tanner doubled their advantage in the fifth minute of stoppage-time, linking up well with Jake Jervis before slotting home.
