Oh boy, this is a long one so strap in. For most of the 2010s, the Pittsburgh Pirates never had a steady first baseman. Even when they were in the playoffs in 2013 to 2015, they never had one guy who consistently was considered an answer at the position.
In 2010, the Pittsburgh Pirates opened the decade with a former 1st round pick at first base – Jeff Clement. Clement was a 1st round pick, and 3rd overall selection by the Seattle Mariners in the 2005 draft. Yes, Clement was selected before players such as Andrew McCutchen, Ryan Zimmerman, Ryan Braun, Troy Tulowitzki, Jay Bruce, and a bunch of other names the Mariners probably wish they had taken instead.
