Diamondbacks 7, Nationals 4

The Diamondbacks are 16-8 in their last 24 games and are 7-0-1 in their last 8 series.

The Nationals have been streaky. They lost 5 in a row, then won 5 of 6, then lost 4 of 6. They are 26-30 on the road and 27-45 against teams with a winning record.

Arizona has won 4 of Montgomery’s 5 outings, but -165 odds don’t give you the value you want on a bet.

PASS.

Thirteen of the Diamondbacks’ last 16 wins have been by multiple runs. They have scored 5 or more runs in Montgomery’s last 5 starts, averaging 7.6 runs of support.

Nine of the Nationals’ last 10 losses have been by multiple runs.

BET DIAMONDBACKS -1.5 (+115).

The highest total in their 3 meetings this season has been 7. Four of Arizona’s last 6 games have had at least 9 total runs while 7 of Washington’s last 11 have reached at least 9 runs.
