Astros manager Joe Espada made the declaration before today’s spring training game vs. the Mets.
Today, Houston Astros manager Joe Espada declared the team would open the season with a 5-man rotation, a reversal from earlier statements about using a 6-man rotation this season.
While the Astros can still employ a 6-man rotation at various points this season, it does perhaps signal a lean towards more traditional relievers on the team to start the season, before swapping arms and moving to a 6-man rotation later on.
The Astros signed Tatsuya Imai from Japan this offseason, and he is used to only pitching once per week on the NPB schedule. It is one of the biggest reasons the Astros will likely use a 6-man rotation this season, to keep things as close to “normal” for Imai in his first season in MLB.
Most likely projection for the Astros initial 5-man rotation would be Hunter Brown, Mike Burrows, Tatsuya Imai, Cristian Javier and Lance McCullers Jr.
It will be worth watching to see if pitchers like Spencer Arrighetti, A.J. Blubaugh, and Ryan Weiss pitch out of the pen to start the season, or go to Triple-A Sugar Land to stay stretched out. All three would be unlikely to be in the bullpen at the same time, as at least one of them would be the proposed sixth starter, and would need to be stretched out to go 5 or more innings.
