I thought this was the case, that Wyness and Ritchie scored hat-tricks in the same game.

Alloa 0-6 Inverness CT
Hat-tricks from Dennis Wyness and Paul Ritchie destroyed Alloa as Inverness Caledonian Thistle won a very one-sided affair at Recreation Park.
After six minutes, Wyness grabbed his first goal from close range, followed by a second from 18 yards, capitalising on a slip by goalkeeper James Evans.
When Wyness slotted in his third goal after 21 minutes from just outside the area, Alloa knew they were in deep trouble.
The pressure continued and with 27 minutes gone, Ritchie cracked in the fourth goal, high into the net from 22 yards.
Caley continued strongly in the second half with Ritchie adding the fifth goal after 71 minutes before completing the rout with the sixth, and his third, with 11 minutes left.
Alloa: James Evans, Valentine, Seaton, Watson, Thomson, Christie, MacDonald, Derek Ferguson, Hamilton, Hutchison, Stevenson. Subs: Knox, Walker, Gillan, Gareth Evans, Hogarth.
Inverness CT: Brown, Tokely, Golabek, Mann, Munro, McBain, Duncan, Wyness, Ritchie, Hart, Robson. Subs: Christie, McCaffray, Low, Keogh, Ridgers.
Referee: C Thompson

DENNIS WYNESS saw Caley Thistle to a 5-2 First Division home win over Raith Rovers last night.
The striker grabbed a first-half hat-trick, as well as a goal in the 71st minute.
Thistle took the lead after six minutes when Raith keeper Simon Miotto panicked and handed Wyness a simple finish.
Caley went 2-0 up when Wyness flicked the ball home and t h e striker completed his hat-trick with a volley.
After the break, Scott Crabbe pulled one back for Raith but Wyness restored his side's advantage by grabbing his fourth.
