ROTISSERIE: We're still running, against the chagrined (defense)

The All-Star break gives us a chance to check back in on the stolen base category, to see if the gains noted in our last look at the quarter mark are still holding. Although the break is slightly past the midpoint of the season (AL teams average 91 games played, NL teams average 90 games played to date), our use of the rate stats should normalize the handful of extra games. As a reminder:

Stolen Base Opportunity % -- how often does the runner steal when he gets on first base: (SBO%) = (SB + CS) / (BB + Singles + HBP)

Stolen Base Success Rate: (SB%) = SB / (SB + CS)

 

League level data

Both leagues are still running at a 10% SBO% rate, but the NL has boosted its success rate from 78% in the first quarter to 82% in the second quarter....
