An ongoing article calculating the 2011 Toronto Blue Jays aggressiveness on the base paths.While a crude manner in which to measure steals (as it does not take into account outs, additional baserunners, occupation of second base, etc), SBA (Stolen Base Attempt Percentage) is the ‘industry standard’ in fantasy baseball circles when measuring team & individual player SB aggressiveness.
Another crude metric for speed is the Speed Score, developed by Bill James. This metric will be revisited in a June update, once sample sizes have grown.
Also on tap, base advancement.
For now, back into SBA.
The equation is
(Stolen Base Attempts) / (Singles+Walks+Hit by Pitch)
Note: Some use HBP, others don’t. Since an HBP gets a runner to 1st base, it will stay in this set of data
Toronto Blue Jays
Heading into the 2011 season, the message coming from the Jays was clear > We’re going to run.
For reference’s sake, the 2010 Jays had an SBA score of 6.03%. This means they attempted a steal roughly 6% of the time that the opportunity represented itself, using the admittedly flawed SBA equation. This placed the Jays near the bottom of the AL, 12th out of 14 teams. The 2010 AL average was 9.45%.
Moving onto the 2011 season
2011 SBA Data in table format – As of April 13th
2011 AL SBA Chart
(red = average, star = Jays)
The AL SBA or attempt average is 10.7%, the Median is 10.82%.
The Jays are slightly above the pack, averaging 11.93%, which is quite a gain from 2010.
Will it Continue?
Will the Jays continue to stay above the AL average in SBA? Also, how will the team end up placing in other metrics such as Speed Score?
These stats will be revisited in early June.
