​As the best starting pitcher left on the free agent market, Dallas Keuchel has drawn interest from teams like the Atlanta Braves and ​Cincinnati Reds. However, most teams aren't willing to meet his reportedly high asking price. 

If he remains on the market long enough, a return to Houston could be feasible. 

​​Counting Keuchel, the Houston Astros have lost three-fifths of their 2018 rotation, as free agent Charlie Morton signed with the Tampa Bay Rays and Lance ​McCullers Jr. likely won't pitch in 2019 after undergoing Tommy John surgery. This leaves the Stros with a big need.

But if Keuchel is asking for a contract similar to what Yu Darvish received last offseason, it makes sense that there hasn't been much progress in talks with teams interested in him.

​​If Keuchel's market fails to develop much in the coming weeks, there's a chance his price could drop enough for the Astros to afford him. They may be able to sign him to deal similar to the three-year, $75 million contract Jake Arrieta received from the Philadelphia Phillies during Spring Training, but even that might be a little too steep.

This one could drag on for a while.
