Grantham has been dismissed seven times this season with four run outs.
Some long-time players wouldn't have been run out four times in their career.
"I think it's just because of the T20s, there's been a few mix-ups, obviously you start to take a few more risks in the shorter format," he suggested.
"The majority of the time it's just been a lack of communication and poor calling, I've got a lot to blame for it, it's something we definitely need to work on."
The left-hander started the season on a bad note, being run out for 23 against Wodonga.
His last three dismissals have all been run outs.
Grantham posted 15 against Tallangatta, a duck against New City and five in the first 50-over clash with Wodonga Raiders.
He's had three different partners during the dismissals, with Matt Wilson and Jarred Lane joining Ryan Beveridge (twice).
"Oh mate, it's the most frustrating thing, especially when you feel like you're batting well and then that happens, it definitely puts a dampner on the day, it's going to be a long day following that," he laughed.
Any player, at any level, who's been run out knows it takes time to 'cool down', but Grantham can see the funny side.
"(Laughs loudly) I guess you could say that, the first five minutes you're a little bit annoyed but, at the end of the day, it's only a game, at the same time at provincial level, you want to make sure you get on top of these things and make sure it doesn't happen quite as often as it has," he explained.
While Cricket NSW doesn't keep records on individual associations, its honorary research librarian Colin Clowes was surprised to hear of so many run outs in such a short time.
"It's somewhat unusual, I haven't heard anything like that," he offered.
"Steve Waugh was stranded on 99 in a Test match when the last three players were run out, the last one being his brother (Mark), who was running for an injured Craig McDermott.
"Don Bradman was run out three times in his first 22 matches and then only once in the next 212 matches, so he (Grantham) can always improve, like Bradman did."
Like any cricketer, Grantham would be delighted to draw any comparison with the game's greatest.
"Hopefully next time you call me, it's for making some runs," Grantham joked.
It seemed only fair, given what a 'good sport' Grantham was, to reply: "I promise I will call you after your century on Saturday."
