Yup. Yorvit Torrealba: Designated Hitter.
First baseman Mitch Moreland's been struggling lately and Torrealba got three hits in Game 3, and if there's anything we know about baseball managers and postseason baseball, it's that they have short memories. Still, it's worth mentioning, if only in passing, that Torrealba's career OPS (697) against right-handed pitchers is more than a hundred points lower than Moreland's (806).
There's a change in left field, where David Murphy replaces Endy Chavez, who started in Game 3 but went hitless in three at-bats.
Oh, and there's one notable non-change: Despite fouling 13 baseballs off his lower extremities in Game 3 and limping through most of the game, Adrian Beltre's back in there at third base. Maybe it's all a clever ruse, and the first time he's on base he'll steal the next base standing up.
