Extreme heat and howling winds made for a home-run heaven for hitters, but it wreaked havoc on defenders and even got dangerous, with an umpire and Mariners pitcher leaving the game.

Ian Happ homered twice and drove in four runs, and the Chicago Cubs held off Cal Raleigh and the Seattle Mariners for a 10-7 victory.

The Mariners lost to the Cubs in a game that featured five home runs, surely aided some by the wind, some erratic fielding and a couple of scary moments.

Chicago Cubs lefty Shota Imanaga, on the injured list since May 5 with a left hamstring strain, will return and pitch in St. Louis next week.

Imanaga's return could carry the Cubs' momentum as they make a push into the postseason. They defeated the Mariners 10-7 on Saturday.
