( CNN ) It was an act of frustration perhaps more commonly associated with golf 's fictional anti-hero Happy Gilmore than the world 's reigning No 1. player . But when Rory McIlroy pulled his second shot on the eighth hole of the WGC Cadillac Championship into a lake Friday , he might as well have been channeling the much loved Adam Sandler character . Before continuing his round with a dropped ball , the four-time major winner launched the 3-iron used to play the offending shot into the water as well . `` ( It ) felt good at the time , '' a rueful McIlroy later said of the incident in comments carried by the PGA Tour website . `` I just let frustration get the better of me . It was heat of the moment , and I mean , if it had of been any other club I probably would n't have but I did n't need a 3‑iron for the rest of the round so I thought , why not . '' The club `` must have went a good 60 , 70 yards , '' he joked . McIlroy composed himself to finish with a second round of 70 , leaving him one-under for the tournament and eight shots off the pace set by leader JB Holmes . While an improvement on last weeks performance at the Honda Classic event , where he failed to make the cut , the Northern Irishman 's frustration with elements of his game was still clear . `` I think every golfer feels it because I do n't hit shots like the one I hit on 8 on the range , '' he said . `` That 's what really bothers me , the fact that I get out on the course and I hit shots that I 'm not seeing when I 'm in a more relaxed environment . `` So it 's a little bit of mental , a little bit of physical . It 's just everything is not quite matching up . '' Elsewhere on the course , Ryan Holmes scored a two-under-par 71 to remain in second position overall , two shots behind Holmes . Former world No 1. , Adam Scott carded an impressive 68 to finish the day three shots off the pace at six-under while Bubba Watson and Henrik Stenson are tied for fourth on four-under .
