The veteran paceman, who has already come out of "retire- ment" at least twice, has finally decided to hang up his bowling boots and Petrie believes there would be no more fitting finale than to beat Uddingston in today's showdown at Hamilton Crescent.
Torrential rain overnight on Friday means the match, originally due to take place yesterday, has been carried over but the delay has merely heightened the sense of anticipation for both clubs who were surprise winners of their respective leagues.
Petrie, whose side saw off the fancied Edinburgh duo of Grange and Carlton as well as north-east rivals Aberdeenshire, said: "The guys are desperate to end the season on a high. It would cap a brilliant season for Arbroath but it would also be fantastic if Benny can go out on a high. He has been a great servant to the club and although he's retired a couple of times before he really means it this time. His body has finally given up on him and he has played through some severe pain this year for the team's cause. It gives us an extra incentive to be crowned the best team in Scotland."
McGill, one of the leading wicket-takers in the old SNCL, has claimed 22 victims this season - fourth highest in the CSL Eastern Premier. Team-mate Craig Ramsay has one more and the outcome of today's encounter could hinge on how Ramsay, McGill and their bowling colleagues fare against Uddingston's in-form batsmen.
The Bothwell club's Sri Lankan professional, Ras Priyadarshana, topped the averages in the CSL Western Premier, while Aamir Gul also had a prolific season with the blade, resulting in a belated call-up to the Reivers side last weekend.
However, the absence of leading all-rounder Calum MacLeod, who is on Scotland duty, is a major blow to the hopes of Uddingston who held off a late charge from Clydesdale to win the Western Premier title on net run-rate - their first league title in 79 years.
Veteran spinner Mark Townson is drafted in and skipper Bryan Clarke said: "I doubt if there's a player in the land who could replace Calum but Mark is a handy guy to have on your side and always has lots to offer. We've been without Calum on a few occasions this season and coped so hopefully we can do it again. It has been a special season for the club already but we want to prove ourselves the best in the country."
