She took a break from tennis to deal with mental and physical fatigue from February 2012 to late August 2012. Marino made a comeback the second week of September 2012 at the $25k in Redding, California, losing in the second round to Sachie Ishizu. The next month, in only her fifth tournament since coming back, she defeated fellow Canadian Sharon Fichman to win the $25k in Rock Hill, South Carolina as a qualifier. She then lost a week later in the first round of the $50k Saguenay Challenger to Maria Sanchez, stopping her winning streak at eight matches. In November 2012, at the $50k Toronto Challenger, Marino was forced to retire in her second round match after suffering an abdominal strain. She was supposed to end her season the next week at the $75k event in Phoenix, but had to withdraw following her injury. At the Australian Open in January 2013, her first Grand Slam championship since coming back, Marino made it to the main draw with her protected ranking of 115, but lost to Peng Shuai in the opening round.
