We haven't heard much about Sean Burnett in the last week or so, but we did get an idea of what kind of deal Burnett will likely receive when his fellow left-handed reliever, Jerremy Affeldt, finalized a three-year, $18 million deal with the Giants earlier this week. That's a pretty hefty deal for a set-up guy, but it tells us what the market will be like this winter. There's a lot of money out there, and quality free agents will cash in. Burnett and Affeldt were viewed as the top left-handed set-up guys on the market, and even though Burnett is coming off minor elbow surgery which he had just after the season, he might even have slightly more value than Affeldt. Burnett, 30, is three years younger than Affeldt. While most of their numbers match up pretty evenly, Burnett's strikeout-to-walk ratio over the last three years is higher than Affeldt's, and his ERA+ over that three year span, an advanced stat which adjusts a pitcher's ERA according to the ballpark he's pitching in, is significantly better than the Giants lefty's. Because of Burnett's age, it's entirely possible he ends up landing a four-year contract in the $20-24 million range, a deal which the Nats might be hard-pressed to match. There aren't many quality left-handed set-up guys available this year, and with Affeldt already off the market, Burnett will be able to play one interested team off the other, if he so chooses. The Nats are interested in retaining Burnett, but how high will they be willing to go? Can they pay $20 million or more for a set-up guy when they have other areas they need to address, including bringing in another starter and retaining Adam LaRoche? We shall see.
