Steyn took 3/37 and Abbott 5/31 as Hampshire bowled out Somerset for 106.
Abbott's is the second hat-trick of the 2018 Championship. The first one was by Jordan Clark.
Kyle Abbott was also involved in one of the most controversial moments in South Africa's World Cup history after being dropped at the last moment from the side to accommodate the return of injured Vernon Philander
The 31-year-old, who had two spells at Sussex last season, has played six One-Day internationals (ODIs) and 20 Twenty20 (T20s) for South Africa.
The news of Rillee Rossouw was sudden and Cricket South Africa (CSA) as well as coach Russell Domingo were ‘bitterly disappointed.'
Just like the first day, there were a few sparkling highlights from Day Two as well. We take you through them here.
CSA said Tuesday it wants to hold talks with the agent of Kyle Abbott to discuss a report that the Test fast bowler is on the verge of signing a contract to play county cricket for Hampshire.
Abbott, who played a crucial role in an away series win in Australia — South Africa’s third in a row — is reported to have agreed to sign a deal for three or four years.
He lacks the apparent aggression of Dale Steyn. He lacks the pace of Kagiso Rabada and bounce of Morne Morkel. He may not move the ball like a Vernon Philander would. But throw the ball to Kyle Abbott, and he will win you games.
South Africa's Kyle Abbott cracked open the porous Australian batting with the figures of six wickets for 77 to finish with nine wickets for the match.
