It'll be great for daytime outdoor sporting events.

It won't be as good for night-time or indoor sporting events. The reason for this is that for sports you ideally want fast shutter speed of 1/500s or better in order to freeze the motion. Indoors, or under lights, you won't get that with that zoom lens.

Flash doesn't help at sporting events because the distance is too far, and image stabilisation doesn't help because it won't do anything for motion blur caused by the players moving.

If you find you have to shoot something like that indoors or at night, then you're mostly out of luck, I'm afraid, unless you want to spend significantly more. You may get some success with a 105mm f/2.8 or something but it won't zoom, and other than that you'll be up for $$$$ to get a fast enough tele or zoom.

That said, your chosen lens will be better than any compact camera would be at an indoor or night sporting event - even a "superzoom" or "bridge" camera.

In other words, it's the best you can get without spending many times as much - which may not be worth it. What you have will be great during the day, and you will get good shots with it.
