In case you're wondering, that did in fact lead the league. How did he accomplish that?
With his blazing speed? Nine stolen bases in 15 chances. Nope.
His patience? 107 walks in 719 plate appearances. A little bit of it.
His .310 average? 183 hits in 719 plate appearances. Again, a little bit.
With his power? 47 homeruns, one triple and 37 doubles. That accounts for a third of it.
Here's the thing runs are a nice stat, but they're reliant on lineup construction and in 2000 the Astros had a pretty powerful lineup. Bagwell being the on-base, power hitting machine he was benefited from all the good hitters hitting behind him. Heck Craig Biggio the guy hitting first or second only had 67 runs scored that year. You would expect for him to score more, but in reality while his .388 on base was nice, his lack of power .393 slugging really hurt his ability to get extra base hits and then be driven in. It also doesn't help when you only play in 101 games, but still, there was no way he was catching Bagwell in runs scored.
This is why sabermetrics lumps runs in with runs batted in, it's a nice stat, but tells very little about a player. Case in point Bagwell, in three more games, 10 more plate appearance, 42 more walks, 21 more steals, five less homeruns, 1 less triple and two less doubles, in 1999, he actually scored nine less runs.Why?
He only had Ken Caminiti and Carl Everett as above average hitters hitting behind him.
Runs are nice, but they're heavily reliant on the lineup behind a player.
