90.7z

"90.7z" refers to a 90.7% Zone Contact (Z-Con) percentage, an elite sabermetric indicating a batter's high ability to make contact with pitches inside the strike zone [13]. This metric is used to identify high-floor hitters, such as Yankees prospect Oswald Peraza, who achieved this rate during 2026 Spring Training [13].
