I’d like to get some advice on any good catching drills to practice by myself

Hi Ryan,

Grab a golf or tennis ball and stand say about 1 to 2 metres from a concrete/brick wall. Under arm the ball relatively firmly against the wall so it comes back at you at reasonably good pace and practice catching with two hands first but also one hand swapping between left and right hands.
Keep you eye on the ball all the way into your hands and practice giving with the ball to create what they call soft hands.
If the wall is a bit abrasive, the golf ball especially with come back at different angles and be a great little training drill.
Don’t just catch 20, catch hundreds and keen challenging yourself.
Best wishes
