Carlos Marmol has converted a career-best 18 straight save opportunities. Marmol previously converted 17 straight the end of the 2010 season. He looked like a lost cause a couple of months ago, but he has allowed just four earned runs over his last 21 appearances and now has a 3.88 ERA for the year. Walks continue to be an issue, but the Cubs could potentially find a trade partner this offseason if they eat some his $9.8 million salary for 2013.
