What happened: DeRo identified reduced hand movement as the central adjustment in Gabriel Moreno's swing. The Arizona catcher has eliminated unnecessary moves while building toward elite velocity over the past few years.
Why it matters: Moreno has drawn 49 walks against 65 strikeouts, reflecting the control behind his .303/.382/.464 line. Arizona entered Monday after a 7-1 win secured a series victory.
By the numbers: Moreno recorded 113 hits, 10 home runs, 65 RBIs and 56 runs through 104 games, producing an .845 OPS.
What to watch: Moreno's plate discipline and extra-base production will test whether the adjustment holds through September.
