Lucas Harrell and Bud Norris are the Astros' two best pitchers.

And, according to a report, they've caught the eyes of the St. Louis Cardinals. MLB Network's Peter Gammons says that the Cardinals are interested in Harrell and Norris.

Our friends at HardballTalk see the interest as a "head-scratcher" because the Cardinals have plenty of starters even after the loss of Chris Carpenter.

Harrell won a team-high 11 games in 2012 with a 3.76 ERA.

Norris, meanwhile is set to be the team's highest paid player in 2013, when he'll make $3 million. He went 7-13 last season with a 4.65 ERA.
