Some innings are huge for more than one reason — as the bottom of the seventh was for the Tigers on Thursday.

Not only did they get the good news that X-rays on Jose Iglesias’ left hand were negative — he was hit in the sixth by a 95 mph fastball but it was also in the bottom of the seventh the Tigers scored the two runs that enabled them to down the Seattle Mariners 5-4 at Comerica Park.

With the victory the Tigers lowered their magic number in the American League Central to four — with the chance it could tick down further if the Cleveland Indians lose at home against the Houston Astros on Thursday night.

Either way the Tigers did what they needed to do on the field against the Mariners winning three games in the four-game series.

Iglesias has a bruised left hand and is day to day. Judging by the severe pain he was in when the pitch thrown by the Mariners’ Tom Wilhelmsen hit him; and judging by the speed with which he was whisked away for X-rays the Tigers couldn’t have been faulted for fearing the worst — that Iglesias’ hand might be broken.

But it wasn’t.

As for the game Doug Fister lasted 7-2/3 innings striking out 10 for the win. He’s 13-9.

As they headed into the bottom of the seventh down by a run it was clear the Tigers needed some help offensively.
