Before we get into the steal-iest steals of them all, here are a few that didn't quite make the cut.
Jose Bautista, Toronto Blue Jays: The five-year, $65 million extension Bautista began in 2011 would look like one of the great steals in baseball had he not missed much of 2012 and 2013 with injuries.
Jay Bruce, Cincinnati Reds: Consistency isn't really Bruce's thing, but he's given the Reds plenty of power for a six-year, $51 million extension that began in 2011.
Edwin Encarnacion, Toronto Blue Jays: He's not giving Toronto the same kind of defensive versatility that Bautista is, but the three-year, $29 million extension that Encarnacion began in 2013 is more than a fair price for his power.
Gio Gonzalez, Washington Nationals: He's slipped a bit since his Cy Young-caliber season in 2012, but $42 million over five years is still a good deal for a lefty with Gonzalez's talent.
Alex Gordon, Kansas City Royals: Gordon wields an above-average stick and is baseball's best defensive left fielder, a pretty good package for a four-year, $37.5 million deal that began in 2012.
Jon Lester, Boston Red Sox: A notable hiccup in 2012 aside, the Boston Red Sox have gotten excellent value on a five-year, $30 million extension for Lester that started back in 2009.
Carlos Santana, Cleveland Indians: Though Santana hasn't gotten going yet in 2014, the .784 OPS he has since 2012 is a pretty good return on a five-year, $21 million extension that began that year.
Troy Tulowitzki, Colorado Rockies: My understanding is that the mega-extension he tacked on to an already big extension in 2010 is technically beginning this year, but what he's done for the Rockies so far for relatively cheap is at least worth a shoutout.
