For the last few seasons, Ian Kinsler has been one of the more under-appreciated stars in Major League Baseball. From 2009 to 2011, Kinsler produced +15.8 WAR for the Rangers, putting him in a near dead heat with Robinson Cano (+16.4) and Dustin Pedroia (+16.2) at second base, and ranking him ahead of high profile players such as Prince Fielder (+15.3), Matt Kemp (+14.3), and even his teammate Josh Hamilton (+14.1). Even if you think defensive metrics are completely useless and you want to assume that every player is an average defender at their position, Kinsler would still grade out as top 25 position player, and he’d still grade out ahead of Hamilton. His combination of plate discipline, elite contact skills, rare power for a middle infielder, and his ability to add value on the bases makes him one of the most complete players in the game.
Recognizing his value to the franchise, the Rangers rewarded him with a new five year contract extension today, agreeing to pay him $75 million from 2013 to 2017. This deal will keep Kinsler from becoming a free agent after the 2013 season and allows Texas to retain one of the core players at a price that shouldn’t prove too prohibitive going forward. At $15 million per year, Kinsler won’t have to remain a superstar in his mid-30s to justify the contract – as long as he’s healthy and retains some of the skills he’s shown up to this point in his career, it should prove to be a solid investment by the Rangers.
However, there’s a bit of an asterisk when you deal with second baseman on the wrong side of 30 – they don’t age very well at all. While the reasons behind the phenomenon aren’t perfectly understood (best guesses at the moment include the physical toll taken via turning the double play, and a selection bias effect based on what traits 2Bs get selected for having), the evidence is too strong to ignore.
