Earlier in the offseason, we highlighted a rumor that the Houston Astros were considering pursuit of a top-flight starter. On Monday, Astros owner Jim Crane confirmed that interest.

Here's Crane discussing the Astros' offseason at City Hall as part of the club's World Series trophy tour, courtesy of MLB.com's Alyson Footer:

For those unwilling or unable to listen, here's what Crane says:

"Our group, [general manager Jeff Luhnow] and his team, are actively pursuing a high-end starter. We don't have anything done yet, and it may not be come to be, but we're constantly looking to improve the team."

Crane later added this note, clarifying that the Astros were looking into trades as well as free agents:

The most natural, human-like response is to speculate wildly. As such, it's fair to wonder if Crane is referencing a potential deal with the Tampa Bay Rays for Chris Archer -- in part because the Astros were already known to be interested in Archer, and in part because the Rays would seem to be in a position where they'd be more willing to move Archer than before. However, it seems like the Astros are instead focused upon Pittsburgh Pirates starter Gerrit Cole:

The Pirates had been talking turkey with the New York Yankees about Cole prior to the holiday season. Yet those talks seemingly fizzled for whatever reason. 

Obviously there's no telling if Cole is the pitcher Crane had in mind -- there are free-agent starters available who could be described as "high-end," like Yu Darvish -- or if anything will get done. But the defending champions aren't complacent, and that's bad news for the rest of the league.
