What happened: Walker reached 20 home runs, 20 stolen bases and 100 RBI in the same season. That made him the third player in Cardinals history to clear all three benchmarks in a year.
Why it matters: Walker had already built a notable power-speed line earlier this summer, and the 100-RBI threshold adds a run-production stamp to it. The combination matters because it captures impact in slugging, baserunning and middle-of-the-order production at once.
By the numbers: 20 home runs, 20 stolen bases, 100 RBI; third player in Cardinals history to reach all three in one season.
What to watch: The next watch is how much higher Walker can push each total before the season closes.
