Boxberger (lat/back) will throw a live batting practice session Saturday and could pitch in a minor league game as soon as Tuesday, the Tampa Bay Times' Marc Topkin reports.
He threw a bullpen session earlier this week, and this latest news indicates that everything is going quite well in his recovery. Boxberger is firmly behind Alex Colome in the Rays' bullpen, but he could be next in line for saves if Colome gets hurt or traded.
