Astros vs. Padres MLB Game Betting Analysis

The Under seems to have the most conviction in the betting markets after going through the data, notably the Under hitting in six of the last eight meetings between Houston and San Diego. The Astros have gone Under the total in five of six games when playing inside Petco Park, while also seeing the NRFI hit in seven of eight games – adding more conviction to the Under. Finally, San Diego sports a 26-32-1 O/U record at home this season to average just under eight runs.

Houston to cover the run line seems likely, but is far too expensive. The Astros have covered four of five run lines against the Padres, while the underdog has also covered the run line in four straight meetings – Houston the underdog tonight. While Houston to cover is too expensive, winning outright is plus-money, as they have won eight straight games when facing a team over .500 at night while also winning four straight games off a loss.
