Vizcaino threw a bullpen session Sunday and will be available to pitch Friday, Kevin McAlpin of the Braves Radio Network reports.
Vizcaino's arm ailment isn't an internal issue and was described by Braves' manager, Brian Snitker, as being a "spot" on his elbow. Although Vizcaino hasn't been a reliable closer, having blown three of his 13 save opportunities, he's been a solid source of strikeouts and is posting a strikeout rate of 29 percent.
