Having performed moderately well through a pair of Tuesday night showings, Private Practice is on the verge of renewal. But there's a catch, Deadline reports.

ABC will likely pick up the Kate Walsh-anchored drama, but only for 13 episodes, and under the condition that this will be the show's final season.

Last Tuesday's Private Practice installment drew the series' largest audience in over a year, a 29% increase over its debut Tuesday evening episode the week prior.

Walsh is reportedly on board with the 13-episode pick-up, as the program is competing with other ABC bubble shows such as GCB and Body of Proof for a place on the 2012-2013 schedule and this arrangement would make renewal more likely.

Private Practice airs a new episode tonight. It's previewed above and if you want to help make ABC's decision-making process easier, it's very simple: tune in.
