This is mostly recycled from the Cardinals Lobby of Numbers entry. Damned if I want to sit down and write obituaries, but notice needs to be taken.

A couple things I picked up from BBTF - Seaver faced Brock more than any other hitter, and Brock faced Seaver more than any other pitcher. And, Brock was 35 when he stole 118 bases in a season.

Thanks Magpie.
The first MLB game I attended was left field at Jarry Park in 1969. They were playing the Cardinals, with Lou Brock playing left field. As a kid, I didn't see his defensive shortcomings, he was a star who became a Hall of Famer.
Left field was called 'Jonesville' that first year for the Expos left fielder Mack Jones. I wanted to call the bleachers 'Brock-ville'.

Another one.  Damn.  Lou Brock was the definitive leadoff hitter of his time, and a great World Series performer.  He was very durable, hardly missing any time until after he was 35 and hitting .300 at age 40. I'd venture a guess that a player who is still productive at age 40 is a very good bet to make the three score and twenty.

Lovely piece in The Athletic on Brock. The Great Saint Buck and Angelogoy figure into Brock's story. I have no comment or opinion on the existence of angels, but I am fairly confident that sometimes our attention is caught by something in the environment we need to see and others will miss. That something can terrify or inspire. The best stories are ones where we notice the details that inspire.

Funnily enough it was a fantastic defensive play by Brock that was largely responsible for the start of my lifelong curiosity about baseball (the love of the sport probably came later). It was '73 and my father and I were in Canada (literally) just off the boat from the UK. My father, an avid cricket fan, was trying to understand baseball so we were watching every Game of the Week broadcast possible. Anyway, I remember Brock made a fantastic leaping catch against the fence in Dodger Stadium (I think). The Dodgers had a runner on first who thought it was going to be a hit. Brock took a moment to throw the ball back in because he had hit the wall hard and then ... chaos ensued because the runner, in retreating to first had passed second and then forgotten to step on second on the way back to first. All leading to an inning ending double play. The next inning the first words from the broadcaster's mouth (probably Vin Scully) after the commercial were "as is always the case, the player who makes a spectacular defensive play, leads off the next inning". As an alien to all that is unique about baseball, it took me months to work out what had happened on the basepaths and to understand the baseball lore associated with the broadcaster's statement. Sail on Lou.

might have worked on a drill or two to help him with plate discipline.

Maybe he did. It did improve as his career went along. But Lou was always a free swinger who struck out a lot, and was regularly among the league leaders in Ks. More career strikeouts than Mickey Mantle, among others.

It's true.  His best two years in the plate discipline department were at age 32 and 35.  There aren't too many players who strike out less (per PA) from age 31-35 than from age 26-30, but Brock was one.
