I wouldn't read too much in Mr. Murray's loss to Mr. Tsonga here.
I hope and rather expect Andy Murray will be back to his best form by Wimbledon or the US Open at the latest.
Any title sooner will be a blessing, but most of all let's hope his back has recovered well from surgery so it will be healthy as can be moving forward.
Mr. Murray says
he may never win more majors, but I think he might have some more in him if he stays healthy in body and strong in motivation. Of course, it also depends on how well his competition performs. We will see.

Respectfully,
