The Cubs continue to expand their roster to include young guys who’ve already spent some time with the big league club this year, yesterday calling up Esmailin Caridad.

Caridad, 25, was effective in seven plus innings with the Cubs earlier this year. With AAA Iowa as a starter, he’s put up a 4.17 ERA. If the Cubs let Rich Harden walk next year, Caridad will be among the guys given a shot to win the 5th starter’s spot in Spring Training.
