I came up with some rules for a Huttball match, and I totally made players use Athletics for trying to throw the ball, with the difficulty being related to the range they were trying to throw it. It made sense and worked well.
Earlier today I was listening to a recent episode of Order 66, and they were talking about the bow weapon that shows up in Suns of Fortune, and how if there was a player who really wanted to become a dedicated archer, it was the perfect situation to come up with a custom ability. The RAW kept it simple for those who just wanted to dabble (and because it would have eaten up several valuable pages to describe the new combat skill).
So if you have a PC who wants to be tossing grenades around like it's their job, consider giving them a new ability they can work on for that specialty. If it's a less common thing, I think Ranged (Light) and Athletics are both fine choices for the checks.
Glad I'm not the only one.
In my huttball rules the thrower can use either Ranged (light) or Athletics. Allows a littlemore variety that way (one being Brawn based and the other Agility).
