Former South African captain Shaun Pollock believes Indian opener Shubman Gill could be lacking in match practice upon return from his neck injury in the ongoing T20I series against the Proteas. The 26-year-old registered a golden duck in the second T20I in New Chandigarh, following his two-ball four in the series opener.Gill suffered a neck injury in the first Test of the recent home series against South Africa. He missed the remainder of that game, followed by the second Test and the three ODIs against the Proteas.Gill aside, skipper Suryakumar Yadav also continued his dismal T20I form, scoring only five in India's 51-run loss in the second T20I.Talking about the duo's extended lean run post-game on Cricbuzz, Pollock said (6:46):"Surya is not getting enough runs, so he may be short of form. Shubman Gill was in good touch but then he misses the two Tests and doesn't play the ODIs. And then now what cricket are you coming in with? For now, South Africa have to play on it. They've to try and take advantage of this top three besides Abhishek aren't performing, and they need to keep the pressure on them."He added:"South Africa should start talking about them not getting runs, asking them to play big shots. Keep applying the pressure in different ways because if you don't get off to a good start and are three down, you are basically done. You win like less than 10% of your matches. So once India were three down, it was over even with these long batting lineups."Gill has been in woeful form since returning to the Indian T20I side for the Asia Cup earlier this year. The right-hander has averaged under 24 at a strike rate of 142.93 in 14 matches."From an Indian perspective, they are saving all their runs for the important World Cup" - Shaun PollockShaun Pollock was stunned by the fact that neither Shubman Gill nor Suryakumar Yadav has scored a T20I half-century between them in a combined 31 innings this year. Like Gill, Surya has endured a dismal T20I season, averaging 14.35 at a strike rate of 126.41 in 19 outings."If you had said to me 31 innings between the two of them this year and not one of them would get a 50, you could have bet anything on that. There wouldn't be one Indian fan who wouldn't have bet their whole house, their livelihood, and everything on them getting at least one fifty. So it comes as a surprise. But the only thing I can hope for from an Indian perspective is that they are saving all their runs for the important World Cup when it arrives," said Pollock (via the aforementioned source).Team India has remained dominant in T20Is despite the duo's struggles, winning 14 out of their 17 completed matches this year.
