We are going with the Under here in Game 2 of the double header.

For Texas we have Jon Gray who did not even last 2 innings in his last game against Baltimore who will be upset and ready for a bounce back and you have Garrett who has pitched lights out this year despite pitching for the Marlins as he hasn't gotten much support. Texas has not seen him pitch this year, it makes sense to take the UNDER.

Some starters may also get the 2nd game off in the day/night doubleheader here on Monday.
Take the UNDER in game 2 at night.
