South Africa will field debutant Corbin Bosch in the first Test against Pakistan, starting on Boxing Day.

Bosch features in an all-seamer bowling line-up and will be playing on his home ground at Centurion, winning a Test cap just days after making his one day international debut , hitting 40 not out and taking one wicket as South Africa lost to Pakistan in Johannesburg.

The 30-year-old Bosch joins Marco Jansen, Kagiso Rabada and Dane Paterson in the home attack, getting an opportunity because of a long injury list that sees Ottneil Baartman, Nandre Burger, Gerald Coetzee, Wiaan Mulder, Lungi Ngidi, Anrich Nortje and Lizaad Williams all out because of injury or lack of fitness.

"It's one thing making your debut, but then to make it where you've made a name for yourself in the provincial set-up is another thing," captain Temda Bavuma said of Bosch on Tuesday.

"I think Corbin adds an extra element to our bowling attack, he comes with the extra pace. Obviously, a big, strong guy as well, so one of the guys who can hit the deck hard.

"And he offers a role with the bat as well. We saw in the ODI that he can hold his own with the bat. We're excited for him to see what he can do with the red ball and strengthen our bowling line-up."

The all-pace attack means frontline spinner Keshav Maharaj sits out. "I think it's no different to what we've generally gone with. We back our seamers here in Centurion and nothing has changed," Bavuma added.

South Africa are chasing a win that would guarantee them a place in next June's World Test Championship, as they sit top of the standings after winning their last five tests.

"We accept and acknowledge the fact that expectation has risen. There will be pressure that comes with that. We're coming into the series to win 2-0, but we understand for us to do that, there's certain things that we need to do as a team," added Bavuma.

"Keep things simple, keep doing the small things right and allowing the result to take care of itself."
