Jonny Lomax is set to make his 200th appearance in a Saints' shirt when the Betfred Super League early pacesetters entertain fourth-placed Hull FC on Easter Monday.
Half back Lomax, who is currently celebrating his testimonial year, has been in a rich vein of form this season, scoring six tries and setting up several others for his team-mates.
The England international made his debut against Wakefield Trinity at Belle Vue on March 27, 2009, occupying the full back berth in a 42-18 win.
He will also have a key role to play against the Airlie Birds as Saints bid to maintain their current four point advantage at the top of the table, or even extending it to six points.
Nearest rivals Warrington Wolves travel to Hull KR and third-placed Castleford Tigers face a tricky hurdle against the Catalans Dragons in France and both could come unstuck.
At the same time, Justin Holbrook's outfit will not be under-estimating the Humbersiders who have won their last three matches and were irresistible against derby rivals Hull KR at the KCOM Stadium on Good Friday, storming to an emphatic 56-12 win.
They will cross the Pennines brimming with self-confidence, but will need to be at their best if they have any realistic hopes of tasting victory at the Totally Wicked Stadium where they last triumphed in August 2017.
