Initially a ploy to end the run of mound dominance seen in the late 60's, the designated hitter has certainly been the most controversial position in the game since its inception forty years ago. While the National League remains tied to strategy and small-ball, the American League's adoption of the rule has eschewed this facet of the game with the sole purpose of maximizing offensive production. Undoubtedly, the DH has created the opportunity for many to showcase their great offensive talents, with no better example than all-time great, Edgar Martinez. Of course, DHs don't quite bring the same value as a field player, because they can only impact the game one way: with the bat. So, it's only appropriate that this list will focus on the best full-time hitters at the position. I say full-time, because more and more teams use the DH as a platoon/day-off arrangement, with permanent DHs as sort of a dying breed. Because of the dearth of full-time DHs, we only have the top three designated hitters listed. Onto the rankings...
3. David Ortiz, Boston Red Sox
Following his poor 2009, folks throughout the game were calling for the retirement of David Ortiz. That year, Ortiz hit just .238/.332/.462 and posted the worst K and BB rates of his Red Sox career. However, Ortiz has since silenced his critics by actually steadily improving since that '09 slump, culminating in 2012 with a career high in OPS+ (171) and career low in K%. While Ortiz's late career revival is one that certainly goes against the norms that come with player aging, that doesn't mean Ortiz can't sustain it, at least for a year or two. However, if there is something to derail Ortiz's production, it would be his recent run of injuries. Last year, Ortiz only played in 90 games because of an Achilles strain, forcing him to go on the DL on two separate occasions. As a big-bodied, one-dimensional, aging player, these Achilles issues are certainly concerns with Ortiz's future production. With that said, every significant offensive statistic of Ortiz has been trending upward for several years now, and even if he were not able to duplicate his excellent 2012, he should remain a valuable offensive force anchoring the Red Sox lineup. He was about 3 wins in only 90 games last year, so if healthy, he should be worth at least that much in 2013.
2. Billy Butler, Kansas City Royals
Nicknamed "Country Breakfast" (or at least according to his B-Ref page), Butler ate AL pitchers alive this past season, with a .313/.373/.510 line, including a career high 29 HRs and 107 RBI. Entering his age 27 season, Butler has been remarkably consistent arriving on the big league stage during his 21 year old rookie campaign. The past four years are an especially good example of this consistency, as he has had at least a .291 BA (but never higher than .318), a .361 OBP (but never higher than .388), and a .461 SLG (but never higher than .510). Previously one of the best doubles hitters in the game, Butler finally developed the power Royals fans have been praying for, hitting the aforementioned career high 29 home runs. Assuming last year's power display wasn't a fluke (although you know what they say about assuming...), Butler could very well see his power continue to develop as he enters his physical prime. There's no hiding Butler can't run and can't field, but the very absence of these skills allows Butler to flourish at the designated hitter position and highlights what he is truly good at: flat-out raking. Last year, Butler tied his career high in WAR at 2.9, so it would be pretty plausible for Butler to be around and/or surpass that total this year.
1. Edwin Encarnación, Toronto Blue Jays
Affectionately nicknamed E5 (an homage to his more forgettable times as a starting third baseman), Edwin Encarnacion absolutely exploded onto the baseball landscape in 2012, spending a majority of the season penciled in as Toronto's DH. Although he was always a productive bat, Encarnacion established career highs in just about every offensive category hitting .280/.384/.557 with 42 bombs and 152 OPS+. Without having to worry about his defensive shortcomings, E5 (much quicker to type than Encarnacion...) has thrived in his new role. Thus, perhaps it is no coincidence that E5 has seen his two best offensive production (using OPS+) the past two seasons while spending a majority of his games at DH. One concern with E5 is whether his 2012 is sustainable or not. Last year could very well have been a fluke; it also could have been a sign of a player entering his prime and finally being comfortable. I honestly have no idea which it is, but like with most questions in life, the answer probably resides somewhere in between. Encarnacion put up a career high 4.6 WAR last year, and while I don't think he'll replicate last year's extraordinary offensive performance, I like his chances to at least be a 3.5+ win player next year.
