2015 Offensive Player Stats — Interactive
Before the season began I made an interactive graphic showing the on-base plus slugging percentage (OPS) of our Depth Charts projections for each team. Since the season is almost over and players’ offensive output stats won’t change much between now and October 4, I remade the interactive visual using the player’s 2015 OPS and weighted on-base average (wOBA).
The original Depth Charts projections use a combination of ZiPS and Steamers for OPS and wOBA. The original chart from March is at the bottom of the page for reference. Projections — the expected performance of a player — should fall in the middle of the possible performance spectrum, so the season results will have more spread than the projections do.
The visualization shows each player’s OPS or wOBA as a circle with the size of the circle corresponding to plate appearance. The gray box and yellow line represent summary information about the team. The gray box brackets the middle 50% of players on each team and the yellow line is the team OPS or wOBA. Please note this isn’t the average or median OPS or wOBA but rather how the team performed on the aggregate. Together these elements create a psuedo boxplot.
There isn’t much surprising in the visualization. Bryce Harper is quite the outlier for both OPS and wOBA, and the Blue Jays top the charts as a team. The original visualization with the projections from March are below.
NOTES: The 2015 stats are current as of 10/1/2015 and I limited the players to a those who had a minimum of 50 PAs. The player stats are also broken up by team, so a player traded mid-season will have stats for two or more teams.
I build things here.
Offensive player stats, indeed.
Trayce though!
