They now have a sortable page up where you can look at opportunities and conversion rates of outfielders on 5-star, 4-star, etc. https://baseballsavant.mlb.com/catch_probability_leaderboard?min=25&year=2017 I'd suggest that this forum be a place to discuss these stats throughout the year. They are new, so it is going to take some time to get used to them in order to figure out what they mean. For example, Buxton is currently (as of 5/31/17) 0 for 7 on 5-star plays. Meanwhile, Ender Inciarte has converted 4 of 7 of his 5-star opportunities. Does this mean Inciarte is the better outfielder? Perhaps one way to start looking at these stats is to look at all of the 4 and 5 star plays together. That represents all of the balls that 50% of outfielders wouldn't normally catch. Here is a short list, of all outfielders who have recorded at least 6 of these plays on the year: Jarrod Dyson 9 out of 14 = 64.2% Odubel Herrera 7 out of 12 = 58.3% Byron Buxton 10 out of 18 = 55.5% Jackie Bradley 7 out of 13 = 53.8% Kevin Kiermaier 6 out of 13 = 46.2% Ender Inciarte 9 out of 24 = 37.5% Mookie Betts 7 out of 19 = 36.8% Keon Broxton. 6 out of 19 = 31.6% Other players of note: Max Kepler, 2 for 6, Alex Gordon 1 for 8, Aaron Hicks 0 for 11, Mike Trout 0 for 7, and Denard Span 1 for 10, Billy Hamilton 4 for 12. Is this a good way of looking at it? Then again, Dyson has missed two 3-star oppportunites this year, as has Jackie Bradley, while Buxton hasn't missed any. This would be an interesting set of stats to monitor throughout the season.
