DETROIT -- The Tigers didn’t end their six-game losing streak Sunday at Comerica Park. They didn’t lose, either.

The fate of the Tigers’ series finale against the A’s won’t be determined until Sept. 6, when the two sides begin a series in Oakland. The teams will resume their game in the bottom of the seventh inning with the A’s holding a 5-3 lead.

Oakland pulled ahead with two runs in the top of the seventh. By rule, the inning would’ve had to be completed, with the Tigers given a full chance of at-bats to respond, for the A’s to be declared winners.

Who will be in Tigers uniforms by that point is also to be determined, partly by the July 31 non-waiver Trade Deadline, partly by expanded September rosters that could bring Tigers prospects into the picture.

If that sounds confusing, imagine the sense Tigers hitters had as umpires called for the tarp as Josh Harrison led off the bottom of the seventh inning against Liam Hendriks.

“I saw [plate umpire] Tim [Timmons] behind the plate peek around me down to [crew chief] Mike Winters at third,” Harrison said, “and I’m like, ‘What are you peeking at him for? We’re in the middle of an at-bat.’ And when I looked him, I saw him [nod]. And I’m like, ‘It’s not even raining.’”

The rain had started, enough to send fans scurrying for the concourse. It stopped for a minute, then resumed. The concern was the heavy rain and wind that was to come, and the risk it would’ve put on grounds crew members scurrying to put on the tarp and fans scrambling for cover.

The game was stopped at 3:29 p.m. ET. A’s players stood in front of their dugout, asking why they couldn’t complete the inning to make the game official. Tigers right fielder Nicholas Castellanos was at the Tigers' dugout steps asking the same. The downpour arrived about five minutes later.

It was a tricky situation for Winters and his crew. The Tigers and Pirates played through forecast severe weather last month at Comerica Park, producing the odd sight of two teams playing in front of a completely empty stadium. Fans had been evacuated to the concourse due to looming storms, but the game continued. Christin Stewart slipped on the grass in that game and suffered a right quad strain that forced him onto the injured list.

On Sunday, both teams and the umpires knew a line of heavy storms was headed for Detroit. Tigers manager Ron Gardenhire said he lined up his pitching anticipating a potential delay, holding back long reliever Nick Ramirez and using middle reliever Buck Farmer to replace starter Gregory Soto in the fifth inning.

“We knew it was coming,” Gardenhire said. “We just didn’t know when it was going to get here.”

The temperature dropped from 76 degrees at first pitch to 67 degrees by the seventh inning, and the skies grew dark enough that the lights were on by the sixth inning in mid-afternoon.

Castellanos had a heavy influence in Sunday’s game, scoring two of Detroit’s three runs and preventing at least one Oakland run with a leaping catch on the right-field warning track. He could be off the Tigers' roster by the time the game resumes in September. The slugging right fielder and pending free agent is a strong trade candidate come July. Harrison, too, could be moved, requiring the game to resume with a pinch-hitter.

Likewise, the Tigers could have outfield prospect Daz Cameron and shortstop prospect Willi Castro on their roster by Sept. 6, thanks to expanded rosters.
