Masterful means showing complete command of a skill. A masterful performance, masterful control, handled it masterfully.
Careful writers once insisted it meant domineering and that masterly was the word for skill, but that battle is long lost and masterful now means skilled in ordinary use. It is high praise and should be saved for it.
