Before you play summer ball, genuinely weigh the options against your goal. Putting on 10-12 lbs and adding 15-20% to your lifts may be a better use of those precious months than getting 20 sporadic innings across 2 months of long bus rides. You can work on executing that 72 mph curveball all summer, but the best thing for that pitch might actually be not being 170 lbs with average strength and numerous mechanical inefficiencies.
