B. Dr. Leo Beck, author of Reach the Stars, believes athletes put too much pressure on themselves to succeed (112).

MLA format states that the author and page number must be mentioned, but if the author's name appears in the sentence it does not have to appear again in the parenthetical reference. Because Beck is mentioned, just the page number needs to appear in the parentheses. 
B. Dr. Leo Beck, author of Reach the Stars, believes athletes put too much pressure on themselves to succeed (112).
