Twins rookie Bailey Ober starts against Astros ace Zack Greinke

HOUSTON — Another hot and steamy day in Texas, but the roof will be closed at Minute Maid Park as the Twins and Astros meet in the second of a four-game series (7:10 p.m., BSN).

Griffin Jax pitched five strong innings on Thursday as the Twins won the opener 5-3.

Bailey Ober (1-1, 4.94) gets the start for the Twins against the AL West-leading Astros, who will use ace Zack Greinke (10-3, 3.65).

Josh Donaldson's gig at DH Thursday night was successful as he recovers from a slight hamstring strain, and he'll be back at third base tonight for the first time in a week.
