The 23-year-old's incredible reflex save late on in our 1-1 draw with Leeds United on 11 May is one of 10 saves shortlisted for the seasonal award - vote for Toni here.
The Czech goalkeeper had already produced a smart stop to deny Leeds the opener in the first half and then bettered that in second-half stoppage-time to somehow tip Sean Longstaff's powerful attempt from close range onto the crossbar in the 98th minute to help secure a point.
Coming in for his first Premier League start of the campaign away to Sunderland four games prior, the young shot stopper went from strength to strength in our remaining games and produced big saves at key moments to play a vital role in our league run-in.
Voting is now open and will close tomorrow (Wednesday 27 May) at midday (UK).
Your votes will be combined with the choices of an expert panel to determine the winner, which will be announced at 2pm on Friday 29 May.
