The first right fielder for the Mariners was LeRoy Stanton. He played the first two years in the Mariners existence. He had a pretty good year for the expansion team. He hit .275 with 27 home runs and 90 RBIs in 1977.
The next season, he spent more time at DH and LF. His second and last year in Seattle, his performance went down. He hit .185 with three home runs and 24 runs driven in. I have to remember the expansion year for his success.
The next right fielder to come onto the scene was Leon Roberts.
