Frank Franklin II/AP As strikeouts continue to soar in baseball, so do strikeout-to-walk ratios. White Sox left-hander Carlos Rodon and Cubs right-hander Adbert Alzolay have joined the trend. In the American League-National League era starting in 1901, the top 11 seasons for K/BB ratio are the last 11. The 2019 season leads the parade with 2.69 strikeouts per walk. The ratio is a tad higher in 2021 — 2.70 — through Sunday. With 62 strikeouts and 12 walks, including 13 strikeouts and no walks in six innings Friday against the Yankees, Rodon’s ratio stands at 5.17. Alzolay, who struck out six and walked none in seven innings Saturday against the Cardinals, has an even better ratio at 6.43 (45 strikeouts, seven walks).
