The Rangers and free agent A.J. Pierzynski are closing in on a one-year deal, sources tell Ken Rosenthal of FOX Sports (via Twitter). The deal is still pending a physical and is not yet done.

The Octagon client met with Rangers brass on Tuesday in Arlington and the club reportedly has done extensive homework on him. Pierzynski would fill a major gap behind the plate for the Rangers, who lost Mike Napoli. The catcher posted a .278/.326/.501 batting line in 520 plate appearances with 27 home runs in 2012. Pierzynski also appeared in 135 games, reaching the 100 games threshold for the 12th consecutive season.

Texas lost out on a big name free agent earlier today when Edwin Jackson agreed to a four-year, $52MM deal. If Pierzynski signs with the Rangers, he'll have Geovany Soto as his primary backup with Eli Whiteside as an additional option. The 35-year-old ranked 30th in MLBTR's list of top 50 free agents this winter.
