Was Billy Sunday the first evangelist to equate the "altar call" with salvation?

According to this article from the The Society for Effective Evangelism : > Up until Billy Sunday, altar calls were invitations for seekers to come to an after-meeting or inquiry room where counselors would help people understand their heart condition. These ministers worked in concert with the Holy Spirit to help seekers repent and yield to God, and to pray that God would save them. Someone was saved only when they were born again—when the Holy Spirit came into them. Conversion and being born again meant the same thing. Of course, I've been to _many_ Christian events that feature altar calls and even more where the speaker simply asks non-Christians to "pray the Sinner's Prayer " with them. I assumed the practice went back at least to Revivalists such as Charles Finney, but according the the article, evangelists before Sunday provided individual counseling before telling people they were saved. Is there any evidence the practice of "salvation by altar call" is older than Sunday?
