Maton signed a one-year, $1.55 million contract with the Astros on Tuesday, avoiding arbitration, Chandler Rome of the Houston Chronicle reports.
Maton struggled to a 4.97 ERA in 25.1 innings for the Astros after a midseason move from Cleveland, with his strikeout rate plummeting from 34.3 percent prior to the deal to 20.2 percent for his new team.
