Last season, 24-year-old rookie Aaron Fletcher made his Major League debut for the Seattle Mariners. Fletcher, who came to the Mariners in the 2019 Roenis Elías trade, did not pitch very well. His ERA sky scraped to 12.46, though most of that is due to pitching just 4.1 total innings. In those 4.1 innings, Fletcher served up six earned runs and seven walks, even hitting two batters just for fun. I’ve always said that hitting a batter is more efficient and intimidating than walking them.
With such a small amount of MLB service to work with, it’s hard to draw any conclusions about Aaron Fletcher.
