Almost a year ago to the day, Jordan wrote a post exploring Billy Hamilton‘s value in our league. To sum his piece up: Hamilton doesn’t have much value because his only offensive skill is stealing bases, and our scoring system does not reward those much (and in fact, penalizes caught stealings more heavily than it rewards the steals themselves).
So the first question then is: why aren’t SBs worth much here?
The short answer to that is, our scoring system uses linear weights, which tries to match how points are awarded to how valuable real life events are. I suggest pausing this post, reading this explanation of linear weights, and then coming back. It does a better job explaining it than I would, and the explanation is already written. So go do that, then come back.
OK, got it?
Now that you’ve read that and understand the philosophy behind our scoring mechanisms, let’s ask this question: what, then, are SBs worth? We do give points for them, so they aren’t worth nothing.
Of hitters with 1,000 plate appearances between 2014 and 2016 (235 qualified hitters), Hamilton ranks 219th in on-base percentage, 192nd in batting average, 217th in home runs, 232nd in slugging percentage, and 234th in wOBA. Objectively speaking, these numbers define Hamilton as one of the worst offensive players in all of baseball over the last three seasons.
Of course, he ranks first of that same group in stolen bases with 171. Dee Gordon comes in second with 152.
These two players are actually very interesting, because Gordon has proven valuable in our scoring while Hamilton has not. It’s not like Gordon has any pop at all. They have very similar infield hit and line drive percentages, but the dramatic difference is a whopping 14.8% disparity in ground ball percentage and fly ball percentage. Basically, by putting the ball on the ground more, Gordon avoids easy outs, gets singles instead, and ratchets up his points totals little by little.
(To be fair to Hamilton, he’s a tremendous defender. I guess ideally defense would be rolled into our scoring, but there’s just not a good way of doing that just yet.)
Anyway, in a category (4×4, 5×5, whatever) league where stolen bases count, Hamilton goes from being one of the worst offensive players in baseball to being a weapon that can singlehandedly win you a category. Current NFBC ADP data has him as the 12th outfielder off the board and the 54th overall player off the board. But we’ve already established that he has only one offensive skill, that that particular offensive skill is not particularly valuable to real life run scoring, and that literally every other component of his offensive profile ranks at or near the bottom of leaderboards over an ample three year period. So you see the flaw here? Like, it’s very, very clear, right?
Through the lens of our league’s scoring, let’s look at Hamilton over the last three years with (top) and without (bottom) stolen bases:
In 2014, Hamilton got caught stealing a bunch of times. Getting caught stealing a base is one of the worst things a baseball player can do on the offensive side of the ball, and so doing it 23 times in a year will wipe away most of the value provided by those successful steals. Even still, he added over 70 points in 2014 from his baserunning abilities. He’s been more efficient in the two seasons since.
Without the steals, Hamilton is just kinda… bad? He would have scored 288.2 points in 2015 and 417.1 points in 2016. Even with the steals, he’s not worth much. But in 2015 he gained 118.5 points from steals and in 2016 his totals were bumped up by 122. That’s a lot! His steals are essentially adding almost six per week to his totals. It seems small, but in 2016, the difference between being worth 418.1 points and 539.1 points might be rosterability. The former might not even warrant a spot. The latter seems like a useful bench piece.
The other problem with Hamilton specifically is that, because he’s such a horrible hitter, he lends himself to being used as a pinch runner. This means that he likely isn’t in the Reds’ lineup on a particular day, thus he’s not in your fantasy lineup that day, and maybe he pinch runs and steals a base or two. So he’s accruing those points, but your team isn’t. That matters.
But this isn’t about Hamilton. It’s about stolen bases. So let’s look at a couple guys near the top of the SB leaderboard in 2016…
Last year, Jonathan Villar led baseball with 62 stolen bases. But of qualified hitters, he also ranked 23rd in OBP and 42nd in wOBA. So SBs aside, he had quite a good season hitting the baseball. With SB and CS included, he scored 1,042.2 points last year. Without them, he scored 941.2. But while he led the league in steals, he also led the league in times caught stealing, so he sort of cannibalized some of the value of his stolen bases. Still though, what he did on the base paths added more than 100 points to his total. That’s significant.
One of the most efficient base stealers last year was, surprisingly, Paul Goldschmidt. He swiped 32 bags and only got caught 5 times. With those factored in, he amassed 1,197.1 points and without them he would’ve accrued 65 fewer. So that’s 6.5 points per week which, again, is quite a lot even if it doesn’t seem like much.
My take away from this is that stolen bases actually are valuable in our league, but the offensive profile that goes with them must be sound. It’s not really a new revelation, rather confirmation of an existing one. Being fast and fast alone does not (and I’d argue should not) morph you into a valuable player, but being a quality hitter that is also fast can provide a nice opportunity to grab some extra points along the way.
