In fact, based on his multi-year track record Mijares is projected by Baseball Prospectus and Baseball Think Factory to have ERAs of 5.51 and 6.23 this year. He's a pretty good bet to beat those projections, but Mijares has thrown 19 career innings above Double-A and giving him six weeks at Triple-A makes sense if the Twins think it would help him shed 20 pounds or start throwing strikes again. Meanwhile, as Mijares pitches and eats his way off the roster Brian Duensing is emerging as a bullpen alternative.

Duensing has made all of five relief appearances in four seasons as a pro and projects as a potential back-of-the-rotation starter long term, ranking 25th on my annual list of the Twins' top prospects. On the other hand he's already 26 years old, took a big step backward at Triple-A last season, and seemingly has little chance of claiming a rotation spot in the near future, so if the Twins think he has the potential to be an effective middle reliever that may be the best path for Duensing at this point.

However, his high-80s fastball doesn't figure to play a whole lot better as a setup man and left-handed batters hit .283 against Duensing last year, so he doesn't profile as a situational southpaw. Of course, baseball history is littered with mediocre starter prospects who had something click after a move to the bullpen and for better or worse Duensing is likely about as close to MLB ready as he ever will be. If the Twins go with 12 pitchers, it will come down to Duensing, Mijares, Jason Jones, or R.A. Dickey.

YEAR     SERVICE TIME              BAKER        FLOYD
2009     Pre-Arbitration           $0.75        $0.75
2010     Arbitration Year 1        $3.00        $2.75
2011     Arbitration Year 2        $5.00        $5.00
2012     Arbitration Year 3        $6.50        $7.00
2013     Free Agent Year 1         $9.25        $9.50

Both deals cover one year of pre-arbitration and three years of arbitration with a team option for the first year of free agency, and the money is essentially identical. Floyd is 16 months younger than Baker, so he may have more room to improve, and on the surface their 2008 seasons were comparable. Baker had a 3.45 ERA over 28 starts in a pitcher-friendly ballpark, while Floyd had a 3.87 ERA over 33 starts in a hitter-friendly ballpark. However, their Fielding Independent Pitching (FIP) tells a much different story:

FIP                 2008     2007     CAREER
Scott Baker         3.79     3.89      4.05
Gavin Floyd         4.77     6.07      5.40

Floyd won 17 games last year and tossed 206 innings with a 3.87 ERA, but he also walked 70 batters while allowing the AL's most homers (30) and unearned runs (19). FIP suggests that his performance was more in line with an ERA a full run higher and his pre-2008 track record is even worse. Meanwhile, Baker has posted a sub-4.00 FIP in back-to-back seasons and has a career mark of 4.05 compared to his actual 4.23 ERA.

Floyd showed some definite signs of improvement after the All-Star break and could easily prove to be worth $25 million over the next five seasons, so the deal is hardly a bad one for the White Sox. With that said, Baker has clearly been the superior pitcher and from the Twins' point of view his deal now looks even better than it did three weeks ago. Interestingly, the White Sox also offered the Baker-Floyd deal to John Danks, who has the same service time, and he turned it down. Danks had a 3.44 FIP last year.
