When Alcaraz won his first ATP title in Umag his elbow was heavily bandaged, this seems to be a recurring injury, as his coach JCF said before his matches at Hurlingham tournament, which he both lost, it is a exho tournament granted, still he said himself he needed more grass matches., at ;least he is not wearing the elbow brace.
I would have liked him to play a pre grass tournament before Wimbledon, though due to his current elbow problem he couldn't.
I am still out on Alcaraz on grass, not because he is Spanish, it is because of his lack of grass match play.
No doubt he has the skills to be capable on grass, I feel at present he is more suited to HC and clay.
Also the same reason I am out on grass with Ruud, who has not won a grass tour match, though I feel Alcaraz has more game than Ruud has overall.
