You factored in Yelich’s first (age-21) season when he made his major league debut in late July and only played in 62 games. In the four seasons since he has played in 144, 126, 155, 156 games, respectively. True but those numbers are just place holders. I also didn't account for missed games due to injury for Braun and Cain, who have a tendency to miss games due to injury. The point, which is being missed here, is that between the 3 OF positions there is a good chance that there will be 60-80+ starts for a 4th outfielder. Lorenzo cain has averaged 129 starts over his last 5, prime years. Braun, starting at the year of his suspension(when he missed much of the rest of the year with thumb nerve damage), has averaged 115 starts. Even if we didnt include his suspension year he still has averaged less than/basically 130 starts per year over last 4. Regardless of where the OF starts would come from the fact remains that there would be a good number of starts for a 4th OF. So not including starts from a 1st base platoon for braun and DH on road interleague games i still think its doable to keep all 4. That being said i would try to trade Santana, but only for good value. I was reading how the brewers have hurt themselves bc now team know they need to trade Santana and that, to me, is wrong. That was the reason for my iniitial post, I enjoy the back and forth on this forum. Go Brewers!!
