I agree on WPA and hitters, actually. But I'm not the one who brought up pressure and clutch performance, either. It's not something I really believe in for hitters so my point was to show how it's mostly bunk, not because I believe Rosario is either clutch or un-clutch. Regarding Late & Close versus High Leverage (WPA), you're missing the most important component: weighted plate appearances. Late & Close treats all late and close PAs the same. High Leverage weights the most important PAs and grades them according to expected outcome versus actual outcome. In the same inning, one can see PAs of wildly different values based on score and situation. Late & Close would judge these two PAs identically. - Eighth inning, no outs, down by two runs, bases empty. - Ninth inning, two outs, down by one run, bases juiced. Whereas High Leverage would grade those two PAs *very* differently.
