To determine the correct verb form to fill in the blanks in the given sentence, we need to understand the subject and the tense being used. Let's break it down:

1. The subject of the sentence is a "triumphant tennis player."
2. The verb tense being used in the sentence is the past tense, as indicated by words like "to feel," "to see," and "to claim."

Now, let's analyze each blank:

1. The triumphant tennis player (to feel) proud of himself.
The verb form we need here is "felt" because it matches the past tense and agrees with the subject. So, we can fill in the blank as: "The triumphant tennis player felt proud of himself."

2. He (to see) all of his efforts pay off in this one match.
The correct verb form here is "saw" because it matches the past tense and agrees with the subject. So, we can fill in the blank as: "He saw all of his efforts pay off in this one match."

3. The fans (to cheer), the cameras (to flash), and victory (to claim).
The verb forms we need here should also be in the past tense to match the rest of the sentence. So, we can fill in the blanks as follows:
- "The fans cheered."
- "The cameras flashed."
- "Victory was claimed."

Therefore, the complete sentence would be:
