Jon Heyman of CBSSports.com reports that Darren Oliver is leaning towards retirement. The Blue Jays exercised Oliver's $3 million option for 2013, so he'll be back in Toronto if he does decide to come back. The 42-year-old appears to have plenty left in the tank, as he posted a 2.06 ERA and 52/15 K/BB ratio over 56 2/3 innings this season. The veteran lefty might choose to spend time with his family rather than continue his career.
