For some time, I’ve been bizarrely intrigued by Elvis Andrus. Once, he appeared to be the next Jose Reyes, a 100+ run, 40+ steal, fantasy behemoth. While he has been a sturdy fantasy performer, he has often put together great first halves that were never a prelude to greatness. For whatever reason, people seem unaware that Andrus does a Jekyll and Hyde routine in the first and second halves of the season:

Andrus has been caught stealing more times in the second half despite 36 less attempts—both the lack of attempts and success are disconcerting. With pretty close on base rates, the logical conclusion is that the rigors of a season wear Andrus down.
Last week, prompted by a tweet from Matthew Pouliot, I began to wonder if there is a league wide decline in SB attempts and/or success rates for a certain type of players – and whether that is exploitable in fantasy baseball. Basically, are there other Elvis impersonators out there?
The crux of what I found:
- Bulk SBs and attempts went down in the second half by a decent amount. A lot of that came from the players who barely reached high rate thresholds (11 SBs, 16 SB attempts), suggesting that more marginal players who stole or attempted in large numbers (for the first time) likely won’t do so in the second half.
- That said there is always safety in numbers: the stalwarts (B.J. Upton, Angel Pagan, Drew Stubbs, Ichiro, Juan Pierre, and Michael Bourn) who steal at great rates hold speed value from the first to the second half far better than any other group.
- Since 2010, 30 times a player emerged in the second half with 16 or more stolen base attempts while not doing that in the first. In addition, 19 times a player stole 15 or more bags in the second half while not stealing that many in the first (only three of these attempted 16 or more steals in the first half).
- So, if you are trying to make up SBs in the second half, it makes sense to target two groups of players:
- The absolute leaders in SB attempts/bulk SBs from the first half or
- Injured stars and potential break-out younger players.
Basically, going for players who have little track record in accumulating SBs over a long period will likely not give you enough to catch up.
