The fantasy season has largely drawn to a close — sure there’s Pick Six all the way until the final out — so it’s time to start thinking about the offseason. Here at RotoGraphs we’ll be unveiling our keeper rankings, tier by tier, position by position. For outfielders and pitchers, we’ll combine them at some point, too.
Here are your top tier National League outfielder keepers this offseason:
Matt Kemp
The number one producer in fantasy baseball last year according to Zach Sanders’ new calculator, Kemp had a season for the ages. One more home run and he would have had the fifth 40/40 season in the history of baseball. Even with slightly more power/speed combo players in baseball these days, it was an exemplary year. The mercurial 27-year-old center fielder put up career highs in hits, home runs, RBI, runs, walks, and stolen bases. That alone makes him a candidate for regression, but it’s nice to see what peripherals were actually in line with his career work. His strikeout rate, for one, improved over last year (23.1% this year, 25.4% last year) but really just settled into to his career rate (23.4%). Maybe his 10.7% walk rate won’t happen again (career 7.9%), but maybe it will. Kemp walked at about an average rate in the minor leagues and patience and power come with age. Speaking of power, his .262 ISO was a career high, but it comes off a steady three-year improvement in that category. He’s also slowly been shifting from hitting ground balls to hitting fly balls — after putting up a 1.4 GB/FB in 2008, he’s steadily pushed that ratio to the 0.9 he showed last year. First you get the fly balls, then you get the power. His HR/FB rate has followed the same steady progression.
