The often confusing Super Two tag means that Buck and Ziegler ranked among the highest 17 percent of players who have tallied between two and three years of service time. That threshold is always changing, with the cutoff this year coming at two years, 122 days.
Sitting right at the edge was Ziegler, who finished the 2010 season with two years and 122 days. Buck, meanwhile, has racked up two years, 123 days of service time. Prior to this year, no player was awarded Super Two status with less than two years and 130 days of time.
By qualifying for arbitration a year early, Buck and Ziegler -- who both made $410,000 this year -- will be rewarded with a larger salary jump than most players with less than three years of service time. Buck, though, could be subject to a non-tendered contract following another year limited by injury.
Last year, the A's saw Rajai Davis and Joey Devine reach Super Two status. They made $410,000 in 2009 and, by being eligible for arbitration, both received hefty raises, especially the former. Davis took home $1.35 million this year, while Devine earned a paycheck worth $557,500.
Ziegler could potentially double his 2010 salary after compiling a 3.26 ERA and 1.35 WHIP in 60 2/3 innings this season. During his three years in Oakland, the right-handed submariner has put together a career 8-11 record and 2.51 ERA.
Super Twos get to go to arbitration four times instead of the usual three, but don't become free agents earlier than other players, as six years of service time are still required.
Buck and Ziegler join teammates Davis, Devine, Craig Breslow, Dallas Braden, Ryan Sweeney, Kevin Kouzmanoff, Conor Jackson and Jack Cust as arbitration-eligible players.
