With Rocco's penchant for stats, spreadsheets and optimizing match-ups, I'm surprised he made the Maeda to the BP announcement already. Seattle is a very realistic WC opponent and Maeda had back-to-back quality starts against them in July, allowing 3 ER in 12.2 IP with a 17/2 K/BB ratio. The Twins won both games, but Maeda got 2 no-decisions. He did not face Houston or Toronto this season.
Ryan, meanwhile, pitched against Seattle, Houston and Toronto, but not very well. He was 0-1 with a 9.82 ERA, a 7/2K/BB ratio and allowed 2 HR in 3.2 innings against Seattle. Against Houston he was 1-1 with a 8.10 ERA, a 16/4 K/BB ratio and allowed 4 HR in 10 innings. And against Toronto he was 0-0 with 4.50 ERA, a 4/1 K/BB ratio but allowed 0 HR in 6 innings.
And just to muddy the waters a bit, Ober pitched decently against both Toronto and Seattle, but did not face Houston. Against Seattle he was 1-0 with a 4.50 ERA, a 5/0 K/BB ratio and allowed 1 HR in 6 innings. Against Toronto he was 0-0 with a 3.60 ERA, a 7/1 K/BB ratio but allowed 0 HR in 5 innings.
