Toronto Blue Jays Suddenly Promote 4.82 ERA Strikeout Machine Before Athletics Series

The Toronto Blue Jays suffered a 6-1 loss to the Kansas City Royals in their most recent game, with Spencer Arrighetti on the mound and a few defensive miscues compounding the early trouble. Now, Toronto begins a new series against the Oakland Athletics on Monday, featuring Dylan Cease against Jacob Lopez. Before that stretch, the Blue Jays announced a roster move: they promoted 22-year-old RHP Gage Stanifer to Buffalo (Triple-A). In 97.0 innings with the New Hampshire Fisher Cats, Stanifer posted a 4.82 ERA and 133 strikeouts. He has generated strong strikeout rates of 12.34 K/9 in 2026 and 13.17 K/9 in 2025, ranking him as Toronto’s 10th-best prospect.
