The first two sets aside, which were awful, these last two sets have been really impressive from Andy in different ways. He really upped his game in the third, and in the fourth after getting broken it would have been easy for him to roll over and die and basically say that he got everything he wanted from his return from injury, but he's really slogging this out and it's very impressive, regardless of what happens from here on in. I'd obviously prefer him to serve better, and to have fewer UFEs, but he's like a different player again (obviously partly helped by Lee's meltdown).
Good to see him not giving up like he might have done in the past when he wasn't playing well.
Everything he's hitting is flying in now - really good to see him work through the earlier problems.
