The Tigers, possibly spurred on by the toll playing third base took on Miguel Cabrera's body last season, sent Prince Fielder to Texas for second baseman Ian Kinsler in a rare one-for-one blockbuster trade.
It made sense for both teams, but especially for the Tigers because, as Michael Rosenberg of Sports Illustrated wrote shortly after the deal, they already had the best offensive first baseman in baseball when they signed Fielder in 2012.
The Tigers could have kept Fielder, withstood a few April boos, and watched him produce. The problem was not Fielder himself, or his postseason flop (figuratively and literally), or even his huge contract. The problem was the exact problem everybody saw coming when they signed him: He was the second-best first baseman on the roster, and they owed him a bunch of money into his mid-30s.
Kinsler hasn't been the same player the last two years that he was in 2011, when he had a 30-30 season, but does provide solid on-base percentage numbers (.344 last season) and average defense at second base.
Kinsler will take the place of Omar Infante, who signed a contract with division rival Kansas City in the offseason.
Joe Nathan is the other major addition to the roster, taking over the closer's role vacated by Joaquin Benoit.
The Tigers are betting a lot of money ($20 million through 2016 with an option for 2017) on the 39-year-old Nathan. He's been fantastic the last two years with Texas but also had the lowest average fastball velocity (92.2) and highest slider use (35.4 percent) of his career in 2013.
Doug Fister was traded to Washington in a surprise move for utility infielder Steve Lombardozzi and minor league pitchers Robbie Ray and Ian Krol. It was a baffling move, given how good Fister had been for Detroit since being acquired from Seattle and how little the Tigers received in return.
Dave Cameron of FanGraphs declared the deal a "steal" for the Nationals, citing the low cost for Fister over the next two years and lack of impact talent dealt by Washington.
Dealing Fister does open a rotation spot for Drew Smyly, who was an effective multi-inning reliever for the Tigers last season and has the ability to start but isn't likely to be as immediately valuable as Fister would have been.
Jhonny Peralta will be the biggest free-agent loss for the Tigers. He had the 50-game suspension last season for being involved with the Biogenesis scandal but led all AL shortstops with an .815 OPS in 2013 (min. 425 plate appearances).
Jose Iglesias, acquired from Boston last July, has star potential with the glove at shortstop, but there are real doubts about his ability to hit enough to play every day. He hit just .235/.274/.306 in the second half, which isn't going to play in the big leagues regardless of how good the glove is.
