The final day of the regular season pitted the top four teams in 9-6A against one another and they were both close affairs.
Sachse entered the night already owning a share of the district title, but Rowlett had a chance to grab a piece for itself with a regulation victory on Friday.
The Eagles (10-2-2, 33 points) were able to nab bragging rights for the night with a shootout victory, but in a rare circumstance where both teams had cause to celebrate, it was not enough to catch the Mustangs (11-1-2, 35), who secured the outright 9-6A championship.
Scoring chances were hard to come by for both teams throughout much of the match.
While Rowlett had the better chances early in the first half, Sachse turned up the pressure late, but the match went into halftime without a score.
The Mustangs picked it up during the early stages of the second half, but were denied, including one shot that rang off the post.
The Eagles also had their share of opportunities, but the match ended with a 0-0 tie at the end of regulation.
In the shootout, Rowlett inserted Hudson Meisner in at keeper and he delivered a pair of clutch saves.
That set the stage for Anthony Morales, who converted his penalty kick to give the Eagles the shootout win.
Though North Garland and Garland were already playoff-bound, there was still a matter of seeding at stake for them, as well, on Friday, but the Raiders earned the third spot with a 2-1 victory.
Eric Artega tallied both goals for North Garland (9-3-2, 31), as it closed the regular season on a high note. The Owls (7-5-2, 25) settle for fourth place and a date with 10-6A champion Rockwall in the opening round of the playoffs.
The rest of the bi-district round is yet to be determined as 10-6A still has matches to be played this week.
Although it had no impact on the playoff race, Naaman Forest closed out the district slate with a 4-2 win over Lakeview and South Garland topped Wylie, 5-1.
