Mariners 4, Rockies 2 at Salt River Field
Notable
Mariners starter Wade LeBlanc pitched two innings, allowing two runs on three hits with a walk and two strikeouts. Nolan Arenado smashed a towering solo homer to center on a misplaced cutter in the first. A one-out double in the second led to another run. LeBlanc threw 28 pitches with 19 strikes. He threw some extra pitches in the bullpen after his outing to build his pitch count to 45.
