Baines was described as a 'special player' and 'manager's dream' by David Moyes in his post-match assessment.
But the 28-year-old said Everton's tenth league win of the season was all that mattered.
"That [the win] is the most important thing," Baines told evertontv. "The second goal was important and we deserved it because in the first half we had pretty much all the play. We knew we needed the second goal and the unfortunate thing is that we gave up a bit of a soft one.
"West Brom fought really hard like we knew they would. We knew they had to come out and offer a bit more in the second half of the game.
"If there's any slight twinge of disappointment it's that we didn't steady the ship and go and score another goal, but we have won the game and can't complain."
