In many situations, there can be some 'overlap' in possible verb tenses, and it's generally best to use the simplest. The given example is a series of individual events, not a continuous situation, so it's easier to find and talk about definite breaks in a time line.
I'd like to mention a couple of problems with the example sentence:
Every time this year he got walk- through he won a tournament.
1. I'm not very familiar with tennis terms, but I've never heard of 'walk- through'. If it's the name of a specific thing associated with the game of tennis, the it should be capitalized, and there should not be a space after the hyphen. If it refers (as I assume) to permission granted by drawing of lots to advance without playing because of an odd number of players (We call this a 'bye'), then the indefinite article 'a' should precede 'walk-through'.
2. Before the word 'tournament', the article should be the definite 'the'. As written, the tournament he got the walk-through is not necessarily the same tournament he won.
