Astrology is important in India; even powerful politicians dare not do anything without consulting their preferred purveyor of predictions. So, perhaps South Africa's cricket tourists should join the guru queue with their own list of questions:Is JP Duminy over his hand injury? Will Morné Morkel's quad hold up? How many spinners, and which spinners? And what's up with Hash?The four-match Test series starts in Mohali on Thursday and, having taken the one-day and Twenty20 trophies off India, South Africa know they are near the top of their game.But the XI they will take into the opening engagement of what could be their crowning glory is far from settled.Whether he is batting, bowling or in the field, Duminy is to SA's team what reinforcing is to concrete: the sturdy stuff that holds it all together.So much so that he was not risked in the tour match against a Board XI in Mumbai last week.Russell Domingo seemed less than hopeful that Duminy would be in the mix on Thursday."It needs to heal properly because if something [more] happens he could be out for a long time," Domingo said.No Duminy should mean a fifth cap for Temba Bavuma, who grafted hard for almost an hour for his 15 in Mumbai.Morkel bowled five maidens for no reward on Friday and four overs in the nets on Saturday. Domingo said he had "felt it a little bit" after Friday's play.Morkel's absence could hand a Test debut for Kagiso Rabada who, like Morkel, also went wicketless but bowled with enough fire to catch the eye of a crowd which was chanting his name by the end of the match.But will SA have room for seam bowlers beyond Dale Steyn and Vernon Philander?When asked whether the visitors would field "three pacemen and a spinner or three pacemen and two spinners", a naughty gleam lit Domingo's eyes: "It's one of those options."The opinion that Mohali is among India's faster pitches only complicates the conversation; more so because the wounded Indians are likely to prepare 22 yards of desert.Another twist is that in the most recent Test here - against Australia in March 2013 - spinners took 18 wickets to 15 for fast bowlers - which including a haul of 5-71 for Peter Siddle.Spinners, three in each team, bowled almost two thirds of the total overs. So, go figure.And what of Hashim Amla, who has scored two half-centuries, three hundreds and a double ton in his 10 previous Test innings in India, but has scraped together just 128 runs in eight innings on this visit?That gave Domingo the chance to proffer a prediction: "All players go through periods when they are not as prolific as we've become used to, but you know with Hashim a big knock is just around the corner."Nodding at the window, he added: "He's in the nets now."So Amla was. He won't believe in astrology but, in his inimitable way, he was shooting for the stars...
