On a night when Halloween candy wasn’t on sale and game-time temperatures hit 77 degrees it certainly didn’t feel like October.

Then the game started.

For five innings the Fenway Faithful were on the edge of their seats focused in on every pitch as the Red Sox and Detroit Tigers traded leads.

It was intense. It was loud. It felt like postseason baseball — as did the first two games of the series.

But this wild back-and-forth affair eventually turned into a pumpkin for the Tigers as the Red Sox slugged a franchise record-tying eight home runs en route to a commanding 20-4 win. The AL East leaders took 2-of-3 from the Central-leading Tigers in a potential postseason preview.

After scoring a combined six runs in the first two tilts the two divisional leaders ended this series with an onslaught of offense. It was a fitting end to a series that gave fans a taste of everything October baseball is about — solid pitching timely hitting and monstrous home runs.

In the finale with both team’s No. 5 starters on the hill no lead was safe.

The Red Sox got their first home run of the night on a Stephen Drew two-run blast in the second inning. The 2-0 lead didn’t last long.

The Tigers responded by scoring three in the third capped off by a Prince Fielder two-run homer and the back-and-forth action continued. Jacoby Ellsbory led off the home half of the third with a solo shot to knot the game at 3.

Sox starter Ryan Dempster had more trouble in the fourth as Jose Iglesias beat out a potential inning-ending double play to give the Tigers back the lead. Shane Victorino gave Dempster some nice support leaping into the stands to make the final out of the inning.

As this game would have it Detroit’s lead didn’t last long.

David Ortiz led off the Sox fourth with a game-tying solo blast to center the first of his two homers on the night.
