What happened: Nationals left-hander Foster Griffin detailed how he leans on a seven-pitch arsenal, saying he can mix and match to throw any pitch in any count and at any location. Without top-end velocity, he described using variety and command rather than power as his primary weapon on the mound.

Why it matters: The command-first approach has defined Griffin's recent run of low-scoring starts, giving Washington a dependable arm as the club sits at .500 on the season. A deep, adaptable mix keeps hitters from sitting on any single pitch, a formula that travels regardless of radar-gun readings.

What to watch: Griffin's next turn in the rotation will test whether the seven-pitch approach keeps suppressing runs against a lineup seeing him a second time.
