Just looking at wins and ERA doesn't tell much about what kind of year, or career for that matter, that Jackson is having. With the exception of a slightly higher walk rate, Jackson is pitching just like he did last year, when he posted a 4.03 ERA. He's been pretty much the same pitcher for four seasons now, with FIPs starting in 2010 of 3.86, 3.55, 3.85, and 3.88. His xFIPs are also virtually identical to each other: 3.71, 3.73, 3.79 and 3.81. His other peripherals have also been very consistent over those four seasons. If he pitches like he has his ERA this year should end up much lower too, maybe around 4.50. Not great, but better than anything the Twins starters are likely to end up with. And his 2011-12 ERA's of 3.79 and 4.03 would stand a good chance to top any starter the Twins run out there next year.
