Here are some more details. Here's what Powell's streak really looked like:

8/1 @ DET:
1ST P2
4TH 1B
7TH 1B
9TH 1B

8/2 V CHA:
1ST HR
3RD 1B
6TH 1B
8TH BB

8/4 V CHA:
1ST: 2B
3RD: 1B
5TH: 1B
8TH: 1B
9TH: BB

8/6 @ NYN:
2ND: 1B
4TH: 1B
6TH: ROE6

So he had 12 straight hits (8/1[4th inning] thru 8/6[4th inning]) and 14 straight times on base safely (8/1[4th inning] thru 8/6[4th inning]), but Trilogy says he had only 6 straight hits (8/1[4th inning] until 8/2[8th inning]) and only 12 straight times on base safely (8/1[4th inning] until 8/6[1st inning])....even though he didn't even bat in the first inning on 8/6.
