Here is the sentence said by an old man who I. (I think that he tried to be the first one to show something before all others.)
よし先発はわしがいこう まかせとき!
よし先発はわしがいこう まかせとき!
I tried to find the word in online dictionaries but notI only found anywhere but 「まかせとけ」which means 'Leave it to me'. I would like to know whether the boththese two words relate to each other colloquially.
