Hendricks had to send him clips of his bowling practices, so that Barnes could check whether he still maintained the same bowling action and did not endanger his own back through accidental bad habits.
In 2014, Hendricks spent a lengthy period on the substitute bench and consequently did much training in virtual isolation.
He developed a stress fracture and required a lengthy rehabilitation period in the first part of the summer.
Barnes monitored Hendricks closely to prevent a repeat of the mishap of 2014.
Hendricks nipped out five batsmen in four matches for Punjab this season at an average of 21.80 and an economy-rate of 8.38.
After the first match for Punjab, which was closely watched by Barnes, he notified Hendricks that he was falling away slightly and that his wrist position was not ideal.
“He got better and better,” Barnes said about Hendricks’ performances. He also announced himself happy with Hendricks’ improved fitness levels and the way in which he generally sustained his own action in the IPL.
The high performance manager told Hendricks to improve his fitness levels after the left-arm bowler laboured through the South Africa A-series against the England Lions.
He needed to perform and bowl at pace for at least three bowling sessions per day. He usually started off well, but faded somewhat at the back-end of the day.
“I wanted him to still run in and bowl at pace with the second new ball,” said Barnes.
Hendricks was sensational in the winter of 2013, and captured 11 for 63 in an unofficial test match for South Africa A against India A.
He was also superb in the Ram Slam T20 Challenge, nipping out 28 batsmen in 11 matches for the Cape Cobras in 2013/2014.
His progress was curbed by the back injury and he only played in a couple of Momentum One Day Cup matches and Sunfoil Series matches for the Cape champions in the 2014/2015-season
He showed glimpses of his match-winning qualities with a match-haul of seven for 74 in the final four-day match of the season against the Sunfoil Dolphins.
Hendricks might be selected for South Africa A’s matches against India A later in 2015.
