<div class="news_article"><p>World number four Hideki Matsuyama lost his red-hot form from early this season but hopes a return to Muirfield Village will revitalise him at the Memorial Tournament starting on Thursday.</p><p><div class="getty embed image" style="background-color:#fff;display:inline-block;font-family:'Helvetica Neue',Helvetica,Arial,sans-serif;color:#a7a7a7;font-size:11px;width:100%;max-width:594px;"><div style="padding:0;margin:0;text-align:left;"><a href="http://www.gettyimages.co.uk/detail/690973362" target="_blank" style="color:#a7a7a7;text-decoration:none;font-weight:normal !important;border:none;display:inline-block;">Embed from Getty Images</a></div><div style="overflow:hidden;position:relative;height:0;padding:68.013468% 0 0 0;width:100%;"><iframe src="//embed.gettyimages.com/embed/690973362?et=dBsTDE9sTW1KPWm1AFKXpw&tld=co.uk&viewMoreLink=off&sig=VWgVw2WK5BdHuVRupIjW8Lkv3oiTN6bA3AkFu1hIV14=&caption=true" width="594" height="404" scrolling="no" frameborder="0" style="display:inline-block;position:absolute;top:0;left:0;width:100%;height:100%;margin:0;" ></iframe></div><p style="margin:0;"></p></div></p><p></p><p>Japan's Matsuyama, who won his first PGA Tour event at the 2014 event hosted by Jack Nicklaus at the challenging course he designed, has struggled recently after a superb start to the season.</p><p>&quot;It has been an up-and-down year,&quot; Matsuyama, 25, told reporters on a practice day at the Ohio layout. &quot;Hopefully I'm on the upswing, but to be honest, my swing isn't where I'd like it to be and I'm not putting very well.</p><p>&quot;Coming back to Muirfield Village, there are some special vibes here and hopefully that will encourage my game to play much better than I have been the last couple of months.&quot;</p><p>Matsuyama won the WGC-HSBC in Shanghai at the start of the wrap-around PGA Tour season, captured the Hero Challenge, Tiger Woods' unofficial charity event in the Bahamas, and claimed his fourth career Tour win at February's Phoenix Open.</p><p>Since then, his best result was a tie for 11th at the U.S. Masters and his general play slumped as the talented Japanese broke 70 in just eight of 22 rounds since his Phoenix win.</p><p>This invitational, contested by an elite field of 120, is a key test with the U.S. Open looming two weeks later at Erin Hills in Wisconsin.</p><p>Frustrated by unreliable putting, Matsuyama tried a switch to a center shaft putter but has gone back to his old flat stick.</p><p>&quot;I've been practising a lot with the center shaft putter, hoping to find something, to find a good feeling, to find something that suits me. But unfortunately I haven't,&quot; he said.</p><p>&quot;So I've gone back to my Ace putter this week and hopefully that will wake up and do some good.&quot;</p><p>Other featured players include world number one Dustin Johnson, number three Jason Day, one of a dozen Australians in the field, sixth-ranked Jordan Spieth and Players Championship winner Kim Si-woo of South Korea.</p><p>&quot;Winning here three years ago, I didn't realize how big a tournament this really is,&quot; Matsuyama said. &quot;I've come to realize what an important event the Memorial Tournament is.</p><p>&quot;There's a different feel here at the Memorial Tournament, whether it's the course, the fans, Mr. Nicklaus hosting, it's a special event and always will be to me.&quot;</p></div>
