Stowers will undergo medical imaging after being scratched from Saturday's Grapefruit League lineup due to hamstring tightness, Christina De Nicola of MLB.com reports.
Stowers should be considered day-to-day for now, but if it's any sort of strain, it could jeopardize the outfielder's availability for Opening Day. The 28-year-old has gone 1-for-6 with two walks and two strikeouts in his limited action so far this spring.
