Using some very rough estimates of the cost of a failure to advance each base based on Run Expectancy charts, I get 8(0.18) + 6(0.5) + 1(0.6) = 5 runs per year. Throw in other baserunning situations for another run per year. Yeah, seems very plausible to me. Running it against other 1B only (minimum 10 games. Why 10? Because it's the fantasy limit too, and someone is hardly a 1B if they play the 18th inning at 1B because the manager ran out of players), Prince comes in the 38th percentile among baserunners (51st of 87 overall, 23rd of 37 qualified). Not great, of course, but not awful. Oddly enough, the one qualified that came out the best was Carlos Pena. Other high end offensive 1B (wOBA .350+) that came in ahead of Fielder: Miguel Cabrera, Albert Pujols, Joey Votto, Michael Cuddyer, Mark Teixeira, Mike Morse Other high end offensive 1B that came in behind Fielder: Paul Konerko, Ryan Howard, Adrian Gonzalez
