Athletics prospect Jeremy Barfield has continued this offseason to make the transition to pitching.

The 25-year-old outfielder, and son of former major leaguer Jesse Barfield, began the transition halfway through the 2013 season. He worked in the instructional league then pitched a handful of games in the Dominican Winter League, and is now working at the team's facility in Arizona. The A's are hoping that the hard-throwing lefty can replicate the successful transition that Sean Doolittle has made, now one of the premiere relievers in the league.
