With the 2011 MLB draft approaching quickly, it's exciting to speculate on who the Mariners will get with their second overall pick. I say "who they will get," rather than "who they will take," because it largely (well, entirely) depends on who the Pirates take with the first pick.
The top two projected picks are UCLA pitcher Gerrit Cole and Rice University third baseman Anthony Rendon. If the Pirates take Cole, the Mariners will grab Rendon, and vice versa.
I've already explained why I think Pittsburgh will go for Cole, and that would work nicely for Seattle; Rendon is the perfect fit for their up-and-coming team.
It's likely that we wouldn't see him in the majors before 2013, but that lines up with the expected arrival date of most of the other young guys in the Mariners organization.
However, there's still the possibility that Pittsburgh takes Rendon first (maybe if they lose faith in Pedro Alvarez?), so I'm going to examine both situations.
