Jason Holder's defiant 81 not out helped West Indies recover from an early collapse against South Africa, but the tourists still trail by 73 after day two of the second Test.
The former captain arrived at the crease with his side at 116-6, after a Proteas attack led by Gerald Coetzee had torn through their top order at Wanderers Stadium.
With a diligently impressive performance however, the former number one all-rounder in the world dug his side out of dire straits for a final total of 251 all out in Johannesburg.
His efforts will have spared the blushes of Kraigg Brathwaite's men, though Temba Bavuma's side will still feel they have the advantage heading into the rest of the week.
West Indies had made the best possible start to the first session, dismissing South Africa for a final total of 320 after taking their remaining three wickets for the loss of just nine runs.
Any hope of mounting a steadfast pursuit though appeared to crumble quickly though, with the loss of openers Kraigg Brathwaite (17) and Tagenarine Chanderpaul (1) inside the first dozen overs.
Coetzee, who finished with figures of 3-41, subsequently removed Reifer and Blackwood in quick succession, reducing the visitors to 51-4.
Roston Chase (28) and Kyle Mayers (29) mustered a half-century partnership before they too were dismissed, leaving West Indies over 200 behind with just four wickets in hand.
South Africa likely had high hopes of finishing off the tail with little further effort, but they did not count on the stubborn resistance offered by Holder, who guided their fightback on the front foot.
A 58-run stand for the 10th wicket saw him drag West Indies within three figures of the Proteas, before Gudakesh Motie was caught off Simon Harmer for 17 to curtail their resistance.
Dean Elgar (3 not out) and Aiden Markram (1 not out) added four without loss for the hosts in the final three overs of the day, but at stumps, they could yet come to rue their inability to maintain their cushion.
Holder sets number eight record
Arriving as the late-breaking cavalry for his team, not only did the 31-year-old put his side firmly back in contention but he entered the history books too.
His score of 81 is the best by a batter at number eight in a Test at Wanderers Stadium, exceeding the 78 set by Mark Boucher for South Africa against Pakistan in 1998.
Coetzee justifies inclusion
Having only made his Test bow in the pair's first game last month, it was a less-than-auspicious debut for the 22-year-old, with three wickets across both innings.
Here, he matched that figure in less overs, though his ultimate average was hurt by West Indies' late resistance.
