Gonzales threw 40-50 pitches in the bullpen during the Mariners' first day of summer camp Friday, Greg Johns of MLB.com reports.
The projected Opening Day starter was excited to get back to throwing off a dirt mound for the first time in months, and his arm seemed to be in good condition after he regularly worked off turf during the shutdown. Gonzales had progressed up to 60 pitches in his final Cactus League start back in March, and given the workload he tolerated during his first day of summer camp, he should be able to handle a pitch count close to normal by the time the regular season arrives.
