5:40pm: The Astros are in “serious discussions” with free agent righty Ryan Vogelsong, sources tell Ken Rosenthal of FOX Sports (via Twitter). Evan Drellich of the Houston Chronicle reported earlier today that Houston was not done with its roster, noting that a pitching addition was possible and that Vogelsong was a player the club had confirmed interest in.

Houston added some rotation depth today by dealing for a package that included former MLB starter Dan Straily. But the team is obviously still looking for innings.

Vogelsong, 37, has been a steady presence at the back of the Giants’ bullpen since re-emerging with a stunning season back in 2011. Though his results have been up and down, he has averaged 164 frames per year of 3.74 ERA ball, to go with a 3.92 FIP on the back of 7.0 K/9 and 3.0 BB/9. And it is worth noting both that Vogelsong has posted fairly consistent regular season velocity figures (and was able to amp up his fastball into the mid-90s during the postseason.
