Astros rumors: Ryan Vogelsong, Kyle Kendrick possible starting pitching targets

The (usually) venerable Ken Rosenthal just fired off a tweet indicating that the Astros might be in the market for a back-end starter, naming Kyle Kendrick and Ryan Vogelsong as possibilities.

#Astros still could add back-of-the-rotation starter, someone like Kyle Kendrick or Ryan Vogelsong. Both still on free-agent market.

It's not clear if he's specifically heard those names attached to Houston, or if this is simple speculation on his part. Both pitchers have provided serviceable innings for their clubs for years now, though neither are the type of player to get excited about.

Vogelsong, 37, threw 184 innings last season for the World Series champion Giants with a 3.85 ERA and 151 strikeouts. Vogelsong had a FIP under 4.00 in three of his four years as part of the Giants rotation, topping 179 innings in each of those three years as well.

Kendrick, 30, threw 199 innings for the Phillies last season with a 4.61 ERA and a 4.57 FIP. Kendrick ahd a great ERA in 2011, but his FIP has consistently stayed over 4.00 for the past five years as a starter.

It's possible they could fill the Jerome Williams role for 2015, though hopefully better than, well, Williams filled it.

What do you think? Any interest in either of those guys? Kendrick has shown some ground ball ability while Vogelsong boasts better overall numbers and is much older. What back-end starter would you be interested in kicking the tires on?
