By all means, he is free to choose what he wants to do in relation to his personal expression of faith. But I am fully entitled to view this as an extreme choice in regards to the situation that he is in. As i mentioned earlier, Salah for me is not a tick box activity. It requires sincerity, dedication and a proper investment of one's time and attention.
If The Cricketer feels that this is his way of giving that time and dedication to Namaz due to a small window for prayer, by taking a 3 minute drink break to offer a 3 Raka'at Farz prayer, by all means thats his expression of faith. May Allah accept his prayer.
I personally would have waited for the innings to end or the match to end and offer my Maghrib prayer before offering Isha, with the correct Wudhu and a Niyyat that isn't restricted due to a time, and then I would pray with a relaxed mind before my Almighty lord. Im not here to debate on what is correct from a Fiqh, Sunnah, Hadhith perspective, because this is a never ending debate otherwise.
But yes, if A muslim feels that a laghw activity such as playing cricket can become an obstacle in offering prayer at its precise time, then he should avoid this laghw activity altogether.
