It was almost too easy to call the demise of Ryan Dempster when he was dealt from the Cubs to the Rangers in July. DIPS theory will always have its share of headscratchers, but Dempster’s case was clear cut: with the Cubs, he managed a .242 BABIP and a 9.0% HR/FB compared to career marks of .301 and 10.5% respectively. Upon being moved out of one of the worst divisions and into one of the toughest — and one of the toughest parks to pitch in — Dempster has allowed a .319 BABIP and a 13.5% HR/FB. His ERA skyrocketed from 2.25 with Chicago to 4.64 with Texas. Simple stuff.
Now, thanks to a remarkable charge by Oakland, the Rangers are left with one last game to claim the American League West and avoid the dreaded Wild Card play-in game with Dempster on the hill. Even since being traded out of the cozy confines of the National League, Dempster has had success in the larger American League road parks. He allowed eight runs in six innings against the Yankees, but in his other five road starts, Dempster owns a 2.82 ERA with a 3.48 FIP, including 29 strikeouts against 10 walks in 28.2 innings.
The key difference between Dempster on the road — the Dempster we’ll see this afternoon in Oakland — and Dempster at home? Road Dempster attacks the strike zone.
