First, Mahle cannot pitch in GABP, second, the Reds are not extending Castillo. He will be 30 next season and looking for $100m+. Third why would you extend two players that are making $750k per year. That’s how the Reds got in the situation with Suarez. Let it play out and spend money wisely. Your plan is the same plan they have tried over and over and it just doesn’t work. Trade, draft, development, and turn the roster over every 5 years
