Arizona Diamondbacks starting pitcher Zack Greinke surrendered three earned runs over four innings Tuesday in his final Cactus League outing against the Seattle Mariners.
Greinke hovered around 88-89 miles per hour (mph) with his fastball and topped out at 90.4 mph, according to beat writer Nick Piecoro of the Arizona Republic. It's an alarming sign of decline for a 33-year-old right-hander who averaged 91.3 mph on that pitch in 2016 and 91.8 mph in 2015.
numberFire's algorithms project Greinke to record a 3.69 ERA, 1.25 WHIP and 21.5 strikeout percentage across 183 innings in 2017 while earning a 13-10 record.
