I understand the Tigers and Rangers are not great offensive teams, but this is a great spot for the over. Eduardo Rodriguez has a 5.73 ERA in six career starts against Texas. The Rangers have also scored at least six runs in three straight games.
On the other side Keuchel has faced the Tigers since times over the past two seasons, and has a 6.84 ERA in those games.
Rodriguez has only made one big league start since May 18, and after his strong start against the Angels, I expect him to come back down to earth. Dallas Keuchel is with his third team this season and has been a mess with a 8.53 ERA.
The Tigers' bats have actually started to get going to, scoring at least four runs in four of their last five games.
