Giants Pitcher Carson Seymour Struggles in Third Career Start Against Diamondbacks

San Francisco Giants pitcher Carson Seymour experienced a challenging outing in his third career MLB start on September 10, 2025, against the Arizona Diamondbacks. After securing his first big league win in his second start just days prior, Seymour lasted only 1 1/3 innings, surrendering six hits and four earned runs. His start began with a leadoff home run and he faced 10 batters, failing to fool any of them. This performance contributed to the Giants' 5-3 loss, dropping their season record to 74-72. Seymour's ERA at Oracle Park this season now stands at 7.71 over 15 innings.
