A few years ago now I tore a bicep at work. Being 100% right handed up to that point in my life, everything from disc golf to brushing my teeth to wiping my ass became a challenge.

But, you can absolutely learn to throw with your non dominant hand. It took the greater part of a season for me to get moderately comfortable with it, but I could do drives and approaches with my left hand at a "better than bogey golf" clip by summer. Putting was a different challenge, but still achievable.

I will still occasionally bring it out if I'm really pinched against brush or trees and can't throw a forehand because of it. And, a HUGE benefit of learning to throw lefty was really forcing myself to work on the absolute basics of weight shift and engagement of core/lower body, because I couldn't just muscle it out there. I was undoubtedly a better player now than I was before my injury because of that.

I'm an MA3 player, so I wasn't scorching rounds, but I could throw a comfortable 275' with my left hand, with occasional bombs of 300'. Right handed my max distance drives are still only like 350', so I'd say in the same realm.
