Wednesday night, Tobi Stoner tossed six shutout innings to help his Indios de Mayaguez in the Puerto Rican Winter Leauge clinch a playoff spot. Stoner, who walked three and fanned three, yielded just two hits. He has allowed as many as two runs just once in his five PWL appearances.
Stoner has a sterlig 1.50 ERA in his five PWL appearances. The chart below compares Stoner’s performance in AA, the Arizona Fall League and the PWL seasons.
-Stoner always throws strikes. This is good.
-Stoner’s K/rate has stagnated below 7/9 innings. This is less good.
-Stoner is durable. This is also good.
I’m left wondering whether the decline in Stoner’s walk rate in the PWL and the associated drop in his ERA isn’t due more to the level of play in the league than any dramatic change or improvement in his own pitching.
Stoner’s Indios team opens the playoffs Friday night with a best-of-seven series against Michael Antonini and Ricky Bones’ Leones de Ponce.
