Match factsSeptember 27, 2016 Start time 1000 local (0800 GMT)Big PictureFollowing a Sri Lanka tour that was at times traumatic (the Tests) and at others more encouraging (the ODIs), there is an undoubted sense of anticipation among Australias cricketers about playing in more familiar South African climes. It is no mystery that this is the country where Australia have enjoyed the most away success over the past 20 years or so, for there is minimal adjustment to be made from Australian surfaces. That being said, batsmen and bowlers who strove for weeks to come to grips with Asian pitches and Sri Lankas phalanx of spin bowlers will now have to adjust back up to a little more bounce, pace and quantities of seam bowling.So too will Australias captain Steven Smith need to build a rapport with some new pace-bowling assets, after the decision to rest both Mitchell Starc and Josh Hazlewood from this tour. Daniel Worrall, Joe Mennie and Chris Tremain have all performed well for their states, but the shift to international-level scrutiny and responsibility always stretches the mental resources of young cricketers. A meeting with Ireland in South Africa may be to the slightly less demanding end of the international cricketing scale, but Smith will need to make sure his bowling attack is in good discipline nonetheless. They are being mentored, too, by a new figure - David Saker, the former England bowling coach, is on his first tour as Darren Lehmanns assistant.Ireland, meanwhile, have been stung by a heavy defeat at the hands of South Africa, and will want to make amends against opponents who have also served as useful allies in terms of encouraging this emerging teams rise to the cusp of full international status in the game. The flip side of administrative assistance from Cricket Australia has been several bruising defeats for William Porterfields men, but it should also be stated that their most recent meeting last year ended in a creditable 23-run margin of defeat. Whether the Irish can better that result against an Australian side gearing up to face South Africa will soon be known.Form guideAustralia WWWLW (last five completed matches, most recent first)Ireland LLWLWIn the spotlightWhen he returned home after the first two ODIs in Sri Lanka Steven Smith looked, for the first time in his brief Australian captaincy tenure, like he needed a break. This was as much a mental refresh as a physical one, ensuring his mind would be cleared of the failings of the Test side in Asia ahead of assignments in contrasting conditions. David Warner shone as stand-in captain during Smiths absence, and the full-time leader will be eager to reassert his primacy in charge by starting well against Ireland. He has spoken of wanting the Australian side to be more assertive under his leadership, and it will be fascinating to see how far chests are puffed out at Benoni.Celebrations of a dramatic County Championship victory with Middlesex did not stop Tim Murtagh from fronting up for Ireland against South Africa a few days later. He put in a reasonable shift too, going for fewer than six runs an over as South Africa teed off against other members of the Ireland attack. Against an Australian side new in the country and coming off a trip to Sri Lanka, it will be up to Murtagh in particular to probe for weaknesses in techniques that must now revert to more conventional, harder-wicket methods.Teams newsAustralia named their playing XI on the eve of the match, with right-arm fast bowler Daniel Worrall set to make his ODI debut.**Australia: 1 David Warner, 2 Usman Khawaja, 3 Steven Smith (capt), 4 George Bailey, 5 Travis Head, 6 Mitchell Marsh, 7 Matthew Wade (wk), 8 John Hastings, 9 Adam Zampa, 10 Scott Boland, 11 Daniel WorrallNiall OBrien, who was forced to sit out the match against South Africa because he slipped and hit his head in the bathroom before the game, has been ruled out of the Australia game with a concussion.* Andy McBrine is a possible inclusion for Ireland should they wish to change things up after the heavy loss to South Africa.Ireland (possible): 1 William Porterfield (capt), 2 Paul Stirling, 3 John Anderson, 4 Gary Wilson (wk), 5 Kevin OBrien, 6 Sean Terry, 7 Stuart Poynter, 8 George Dockrell , 9 Tim Murtagh, 10 Craig Young, 11 Peter ChasePitch and conditionsSouth Africa showed there are plenty of runs in the Benoni surface, although by the end of the day it had slowed up and was aiding JP Duminys off breaks. A similar pattern can be expected on Tuesday. The weather forecast is fine.Stats and triviaThis will be the fifth meeting between Ireland and Australia in ODIs.

The leagues said they believed they had found the right balance to help tens of thousands of athletes with a proposal they are calling Flex 21. The extra 21 days off would be in addition to the current mandatory off days, and could be tailored to fit each teams schedule with input from coaches and athletes.Formal proposals still need to be submitted, but the conferences could vote to turn them into NCAA rules at the next convention in January.College sports leaders have been looking into changes to ease the time demands on athletes for several years. At the last NCAA convention, the issue was delayed so more research could be done, including a survey of athletes from all sports. Conference officials seem eager to provide more benefits to athletes at a time when college sports is under legal and public pressure to make changes, including a push to pay athletes. Led by the College Athletes Players Association, members of the Northwestern football team made an attempt to unionize that ultimately failed.NCAA members schools and conferences have in recent years agreed to raise the value of athletic scholarships to cover the federally determined true cost of attendance that goes beyond tuition, books, room and board, and fees. They have also guaranteed four-year scholarships for many athletes and given athletes more say in making rules.We heard from our students that they would like more certainty in their schedules in order to engage in other activities, thhe commissioners said in a joint statement.dddddddddddd We recognize there will need to be a level of flexibility and reasonableness in carrying out these changes, especially with regard to travel, but students deserve time off and we want athletic departments to work in a sensible and appropriate way to provide it. We want administrators to have some degree of flexibility in implementing these rules, but they must be mindful that rest is important to a students health, in addition to their athletic and academic performance.Currently, athletes are generally limited during the school year to 20 countable hours toward their sports per week, with one day off. Countable hours mostly cover practices, competition and conditioning, but does not count travel to and from events. The commissioners proposed expanding the definition of required athletic activities to include but not be limited to activities such as media requirements and mandatory community service.The proposal also includes a mandatory free-time block of eight hours overnight.The 14 extra off days will be on top of the current required two calendar days off per week outside the season. The additional 14 days can be used during the season if agreed to by coaches and athletes.We believe we have found the right balance between helping students participate in sports while also providing them with more down time, the commissioners said. Different sports have different demands and we think the concepts weve agreed to will help tens of thousands of students achieve more balance as they pursue their academic and athletic commitments.---Online:Joint statement from the conferences: http://www.theacc.com/news/commissioners...orts-07-07-2016 ' ' '
