Over at tangotiger.com, MGL asks if the following statement is true.
“Of all of the skills to sign up for past a players prime, however, plate discipline is probably the best one.”
I decided to create an wRC+ aging curve of high walk players. I know the quote is for high plate discipline, but I am not sure how exactly plate discipline should be defined. The article focused on Shin-Soo Choo, so I waned to players with similar walk rates. Over the past three seasons (age 28 to 30 seasons), Choo has walked (NIBB) 12% of the time. So for the curve, I used players since 1980 who had less than or greater than a 10% walk rate between their age 28 and 30 seaons (min 300 PA).
While the high walk players plateau sooner, they begin to decline at the same rate around age 28. High walk players don’t really age any better than lower walk players.
