Yoshinobu Yamamoto won Games 2, 6 and 7 of the World Series. He threw a complete game in Game 2, six innings and 96 pitches on Friday and came back Saturday to throw 2.2 scoreless innings on 34 pitches and induce the World Series-winning double play. A legendary performance.
That was completely predictable. You can’t push it and run Ohtani out there with the heart of the Jays’ lineup coming up. Especially after the way he was throwing.

Powell says he is concerned about the impact of cuts at the statistical agencies. High-quality statistics are "a huge public good," he says. "I hate to see us cutting back on that... I would want to continue investing in that for the good of the general public."
