Astros manager A.J. Hinch said he doesn't feel a need to formally declare a closer, Brian McTaggart of MLB.com reports.
Hinch also said naming a closer doesn't necessarily mean that's who he will give the ball to in the ninth inning of a close game every time. While that doesn't help fantasy owners, the Astros gave up a lot to acquire Giles this offseason and he's still expected to get more save opportunities than Luke Gregerson, who hasn't pitched much this spring due to a mild oblique strain. Giles struggled in camp (7.00 ERA), but Hinch expressed confidence in him despite his rocky spring.
