Yastrzemski, 34, spent six years in the Baltimore Orioles’ farm system before being traded to the Giants in March 2019. Despite making his debut at 28, Yastrzemski established himself as a mainstay in San Francisco’s outfield and played 790 games over seven major-league seasons. During that time, he hit 114 home runs and posted a .768 OPS.

The San Francisco Giants were once in a position to make a postseason push, but they ended up selling at the trade deadline.

It might surprise you that Posey would take such a clear selling posture, but the warnings have been there for months.
