Sebastian Giovinco was next to go close for Juve, showcasing his silky skills twice in the space of a minute to create shooting opportunities, but on both occasions his shots went wide.
Marchetti kept the scores level with a fine save just after the hour mark, tipping Arturo Vidal's deflected effort from 25 yards over the crossbar.
Juventus continued to pour forward in search of an opening goal and they came within inches of finding it through Leonardo Bonucci, but his effort came back off the bar.
Lazio's defence resisted the intense pressure applied by the Juventus attack, however, as they clung on to claim a point.
