HEROIC, South America Rejects and Team Spirit secured the final three playoff spots Wednesday at the $1 million PGL Wallachia Season 8 event in Bucharest, Romania.

Sixteen teams began the Dota 2 tournament with the top eight advancing from the Swiss-system group stage. The double-elimination playoffs begin Thursday with all matches best-of-three until Sunday's best-of-five grand final, where the winner will take home $300,000.

Wednesday's do-or-die Round 5 matches pitted teams with 2-2 records. HEROIC swept GamerLegion, SAR knocked out MOUZ 2-1, and Spirit swept Xtreme Gaming.

HEROIC won in 42 minutes on red and 44 minutes on green. SAR sandwiched a 45-minute win on green and a 58-minute victory on red around MOUZ's 53-minute win on red. Spirit followed up a marathon 72-minute triumph on red with a 40-minute win on green.
