Miley extends himself since the bully has been extended. He can't get the W... and he doesn't deserve one either.
So, after the Altuve out at second trying to get that double, I got interested in some sort of metric that would define team baserunning and have spent the past few innings digging into that. Here's what I found. BsR. It's a metric from Fangraphs that's basically the "baserunning component of WAR." It takes into account weighted scores concerning stolen bases, GIDPs, and other things. Read about it here. The league average is normalized to zero every year. The link I just posted talks about an individual player's BsR, but Fangraphs also has team BsR. I don't know if interpretation of the absolute numbers differs between individual and team. FanGraphs says in the link above that "every nine or ten runs above or below average is equal to about one win." The relative data is illuminating, though. Here's the data for the 2019 AL. Spoilers: The Astros are dead last in the American League. They have a team BsR of -5.7. Assuming Fangraph's Rules of Thumb chart for individuals applies equally to teams, that's considered "AWFUL". (Interestingly, the Rangers are first in the AL with a BsR of 10.2, and after seeing how they beat us partially with baserunning in the bottom of the 9th last night, I can see why they've got a high number.) So, yeah, it's not just your gut feel that our baserunning sucks. It's quantifiable.
