SAN FRANCISCO — As if the big-league season hasn’t been enough of a struggle for the Rays this season, there also have been some major disappointments at the minor-league level.

This was the 20th week of minor league play. According to FanGraphs ( which factors in age and proximity to the big leagues ), newcomer Jadher Areinamo remains the top hitter in the Rays system; the Rays acquired the 21-year old infielder from Milwaukee for Danny Jansen in late July.
