Kahnle (elbow) threw a bullpen session over the weekend, Bill Plunkett of The Orange County Register reports.
This is the first report from the team of Kahnle throwing off a mound this spring. While this is undoubtedly a step in the right direction for the right-hander and shows that he is progressing through his throwing program, Plunkett notes that Kahnle remains unlikely to be ready for the season opener.
