As expected the Cubs just released Ian Stewart from Triple-A, but they also made an even bigger move by designating Carlos Marmol for assignment.
Marmol has been awful this season, making it easy to forget that not so long ago he was one of the most dominant relievers in baseball and his career ERA in 542 innings with the Cubs is 3.50. He’s posted a strikeout rate of at least 10.0 per nine innings every year since 2007, including 10.4 this season, but Marmol’s inability to consistently throw the ball over the plate made watching him agonizing all too often.
Among all active pitchers with at least 500 career innings Marmol has highest strikeout rate at 11.7 per nine innings, the highest walk rate at 6.1 per nine innings, and the lowest opponents’ batting average at .185. Unhittable when he threw strikes, unwatchable when he didn’t.
Marmol is owed about $5 million for the remainder of this season, so he’s likely to pass through waivers unclaimed and could remain with the Cubs in the minors if they don’t find a taker for him via trade. They’d obviously have to eat a bunch of that money, but Marmol is still only 30 years old and still incredibly tough to hit, so no doubt quite a few teams think “if we could just get him to throw strikes …” Chicago almost had Marmol traded to the Angels for Dan Haren this winter before Haren’s health issues nixed the deal and both pitchers have been a mess this season.
