The defender kept a cool head in injury time to secure the Blues' 2-1 win over Wigan on Sunday with a well-taken spot-kick.
Baines told evertonTV: "I spoke to him (Louis Saha) a little bit on Saturday and I think he was still quite keen to take them, which is fair enough.
"But luckily for me he wasn't on the field at the time so I was fortunate enough to get it."
"Hopefully (I will be able to take them)," he said. "Mikel seems to be the main man but I would like to take them.
"But when Mikel comes back I'm sure he will want to be back on them."
