Last year Harper was on base almost 15 extra times out of 100. Nobody is saying a walk is better than a hit. It's not. It's just better than an out 99% of the time. Teams that are on base more score more. Therefore they win more. Your point is valid. The thing is are run producing hits are more valuable than walks. My point is to not just look at OBP but OPS. They had a similar year in that department last year. So one cannot say Harper is a big upgrade over Machado offensively. Harper may have been on base more, but Machado wasnt that far behind offensively overall. Link to comment Share on other sites More sharing options...
ptatc Posted February 1, 2019 Share Posted February 1, 2019 24 minutes ago, Look at Ray Ray Run said: Well, OPS is just saying how many bases you can expect to get per at-bat. That means... that it is a very strong correlation since 4 bases = a run, so someone who averages more bases every at bat, contributes more runs. None of that has anything to do with how strong the predictive correlation is. All that sounds good but until you run the numbers, you don't know.

Sometimes, coaches are willing to accept them as a cost to create a run scoring situation. But in literally every one of those situations, a hit is even better, and in most of those situations, a walk is better. It’s a subtle but important distinction from what you’re saying. Outs aren't a joy, and coaches prefer hits, bit baseball is a sport where a strong of hits is unlikely, especially with the bottom of the lineup. Coaches sacrificing outs to get runs means they don't like the odds of their batters succeeding without sacrificing. So outs aren't great obviously, but they are the better bet in many cases.

It looks like most years it's better than that, but over some long time periods that people tried, wOBA had a higher correlation coefficient than wRC+. I don't see anyone who did just raw OPS in that thread, but raw OPS as I showed above is approximately as good as wOBA and maybe sometimes better. So yeah, OPS has a good chance of being more tightly correlated with runs scored than wRC+. .83 is pretty strong. It would be good to see if OPS was better.

You are correct the adjustment for parks and etc harm it. Similarly to how ops+ is less efficient wRC+ is more efficient than OPS+. if it comes down to it - wRC+ probably does a better job of summing up how truly valuable a hitter is compared to OPS, but the correlation between OPS and runs scored is so strong that you're almost never going to see somewhere where they are a consistent outlier between wRC+, OPS, and runs scored. It's like the difference between walking at 89.9 degrees from north and Due East - you're still going to wind up heading east. So, OPS really does do a great job of summing up a person's performance.

Outs, in general, are almost always bad. Again, it makes common sense but that doesn't meanit's TRUE. Until someone calculates it, you can't definitively conclude this.

Here's someone who did the teams for 2002 and found that runs scored has R2 = 0.46 with wins and runs allowed was 0.70. So neither one of them is a great predictor overall but they're both related, with runs allowed being slightly more correlated at that time. That gets you almost to the Bill James Pythagorean Wins, of (runs scored)^2 divided by (runs scored^2 + runs allowed ^2) as quite strongly correlated with wins. Basically that's a version of "run differential", which is the thing that translates most strongly to wins. Link to comment Share on other sites More sharing options...

The .24 differential is significant. In that year defense had a much stronger correlation. It would be interesting to see it year after year. The differential is obviously the better way. However, as a GM, if it came down to adding the hitter or pitcher, the pitcher would be the answer. In today's game the answer may be different.

Eh, the problem is your giving the pitchers in general the duty of preventing runs while ignoring the fact that pitchers are much more volatile and dangerous commodity... In today's game, adding the position player is probably the answer if both players are equal in value because of the increased pitched volatility.

I don't think the pitchers are more volatile or dangerous. It's more that the analytics are farther along for the hitters than the pitchers. It's more difficult to quantify pitching because of other variables such as the defense. Link to comment Share on other sites More sharing options...

I think the big difference is that something like OPS tells you what happened while wRC+ can tell you what will happen in different situations. A better hitting environment will result in a higher OPS and more runs, but if they moved to somewhere else they would have a lower OPS even if they stayed the exact same talent level. wRC+ is adjusted so it doesn't match the results of what happened exactly, but it can tell you the difference in quality of player in a neutral environment which is probably better for predicting future performance. Of course expected stats should be even more predictive of future performance which will likely mean they are also much worse at telling you what actually happened.

It's rare that a single run will be the difference in a win unless of course it leads to a big inning, but only having two outs to do so is also rare.

I wasn't taking dangerous as likelyhood of injury. I took it in the context of volatile and dangerous to predict performance. I agree that they have a greater likelyhood to get injured. All the more reason to have a greater number of quality ones. Link to comment Share on other sites More sharing options...

It suggests that even at age 26, Harper and Machado's best years are already behind them. If that is the case, I really don't know how the players can deal with this in upcoming negotiations. The only answer is to pay players based on potential, and we already saw in the NFL that they don't like that either. I really don't know what the solution to this is for the players.

It would go against the idea of investing time and energy in following the prospects during a rebuild if you were just going to lose them. There needs to be something like a franchise player tag or max contract or whatever to give those teams a shot. Perhaps the current freeze is giving those guys like Jiminez and Vladimir Jr. an incentive to sign a huge long term deal before they ever set foot on a MLB field...buying out a year or two of free agency.

However, I have no idea what they would need to give up to get that. With most players making their MLB debut at age 22-25, I don't really think there is much they can do. Teams aren't giving up control immediately after a player's rookie season. That is the only way to get them paid during their most productive years. That aging curve is so crazy that there is no practical way to get around it. Teams aren't going to want to pay for potential or decline. If they argue that, there is pretty much zero counter argument from the players standpoint. By the time they've established themselves enough, they're already depreciating assets. It is a losing argument. I think the players have to negotiate a slice of the pie, along with giving up a cap and floor. Otherwise, they have zero leverage. 1 Link to comment Share on other sites More sharing options...
