Saints were held to a goalless draw by Alloa at the Indodrill Stadium as preparations for the new season continued.
The Buddies, who get back to competitive action next Saturday against Stranraer in the Betfred Cup, couldn't find a breakthrough against the League One side in an even match.
Jim Goodwin's Wasps started the game off brightly and almost took the lead when Iain Flannigan almost latched on to Alan Cook's tempting ball across.
Andrew Graham could have done better when he rose above the Saints defence, but his glancing header from a free kick was easily held by Ross Stewart.
Saints had their best spell of the match as they approached the interval.
First Jordan Kirkpatrick, facing the club he left in the summer, had the best chance to open the scoring when he ghosted in at the back post and forced a terrific save from Alloa goalkeeper Craig McDowall.
A minute later, Dale Hilson almost got the Saints ahead from a similar position with his effort flashing just wide of the left hand post.
Gary MacKenzie nodded a header from a Kirkpatrick corner wide after leaping above the Alloa defence, before McDowall was called into action again denying Hilson and Ross Stewart with a fine double save.
The Buddies were on top at the point but entered the interval with nothing to show for it.
They failed to continue that strong finish after the break and it wouldn't be until 20 minutes into the second half before something of note would happen for the visitors.
Lewis Morgan picked the ball up on the edge of the box and rifled a shot that was deflected behind. McDowall made a stunning low stop to deny substitute Gavin Reilly from adding to his goal again in Dundee from the resultant corner.
Alloa arguably should have taken the lead just five minutes later when Kevin Cawley was picked out at the back post. The midfielder was unmarked and has time to pick his spot only to be denied by the legs of Saint goalkeeper Stewart.
Saints had a couple of corners while Alloa's Ryan Hoggan scuffed a free kick wide as the game ended in stalemate.
