'XSET jumped out to a commanding 9-3 lead on Haven, but was slowly reeled in by 100T over the course of the second half. Despite reaching map point at 12-9, XSET was unable to close Haven and wound up losing the first map."
Oops, also this was 11-9, so not quite map point.
"XSET started the series with a 9-3 lead on the first map and ended the series by winning the second map's final six rounds." - might help to specify that these 6 rounds were in the 2nd half. I had to go look up the match to figure out what this sentence meant.
