Pokémon Sapphire: Wattson (Gym #3)

The third gym leader battle in Pokémon Sapphire. I traded in a Dig TM from Pokémon Leaf Green so that Grovyle can counter Wattson's Magnemite and Magneton. The Dig TM is not available until Route 114 in a normal playthrough.
My team:
Level 24 Grovyle
Level 24 Swellow
Level 24 Geodude

Dig makes Grovyle so strong!!
