Rory McIlroy shot 10-over through 36 holes at the Players Championship and missed the projected cut line by 10 strokes.
After his second round, McIlroy spoke with reporters about his frustrations regarding his swing changes.
"Probably the swing issues and where it all stems from, probably like October last year, doing a little bit of speed training, started getting sucked into that stuff, swing got flat, long, and too rotational,'' McIlroy said, per ESPN's Bob Harig.
"Obviously I added some speed and am hitting the ball longer, but what that did to my swing as a whole probably wasn't a good thing, so I'm sort of fighting to get back out of that.
