December 4, 2012
Last month I examined the Twins' free agent pitching options by separating the potential targets into three categories: Top-of-the-rotation starters, middle-of-the-rotation starters, and back-of-the-rotation starters. Friday was the deadline for teams to tender 2013 contracts to arbitration-eligible players and the free agent class grew slightly as nearly 50 players were non-tendered, including the following starting pitchers.
• Jair Jurrjens - RHP - 48 innings - 6.89 ERA - 5.71 xFIP - 19/18 K/BB
Jurrjens had a ton of early success despite mediocre secondary stats, starting 115 games with a 3.40 ERA through age 25, but then he fell apart physically. Knee problems cost him the final two months of 2011 and his 2012 was a mess, as he got knocked around for a 6.89 ERA in 48 innings for the Braves and wasn't much better at Triple-A. Jurrjens is still just 27 and 18 months removed from being an All-Star, but his velocity and strikeout rate have plummeted.
• Tom Gorzelanny - LHP - 72 innings - 2.88 ERA - 4.21 xFIP - 62/30 K/BB
Gorzelanny spent this year in the Nationals' bullpen and had enough success as a reliever that he may want to stick there, but the 29-year-old left-hander was a starter previously and has a 4.61 ERA in 111 career starts. His control is spotty and his fastball tops out in the low-90s, but Gorzelanny has 8.3 strikeouts per nine innings in 46 starts dating back to 2009 and isn't totally helpless against right-handed hitters.
• John Lannan - LHP - 33 innings - 4.13 ERA - 4.70 xFIP - 17/14 K/BB
Lannan was a full-time member of the Nationals' rotation from 2008-2011, starting 122 games with a 4.00 ERA, and was awarded a $5 million salary for 2012 via arbitration. And then they sent him to Triple-A, where he spent the bulk of the season at age 27. Lannan's strikeout rate is among MLB's worst and his control is also sub par, but the soft-tossing left-hander induces tons of ground balls and that alone is enough to make him a viable back-of-the-rotation starter.
• Jeff Karstens - RHP - 91 innings - 3.97 ERA - 3.84 xFIP - 66/15 K/BB
Karstens bounced between the rotation and bullpen during five seasons with the Pirates, posting a 4.14 ERA in 82 starts. He was limited to 91 innings this year with shoulder and hip injuries, but had a 66-to-15 strikeout-to-walk ratio that included the best strikeout and walk rates of his career at age 29. Karstens is a pitch-to-contact, fly-ball righty with a high-80s fastball, but his control is very good and when healthy he's been an effective back-of-the-rotation starter.
• Mike Pelfrey - RHP - 20 innings - 2.29 ERA - 3.35 xFIP - 13/4 K/BB
After four straight seasons with 180-plus innings Pelfrey was shut down in April and underwent Tommy John elbow surgery in May, making the 29-year-old right-hander a big question mark for 2013. Pelfrey was the ninth overall pick in the 2005 draft and never quite developed as well as the Mets hoped, balancing poor strikeout and walk rates with lots of ground balls for a 4.36 ERA that's less impressive than it looks thanks to pitcher-friendly environments.
