CLEVELAND -- Closer Joe Borowski is ready for simulated action and starter Jake Westbrook is ready for the real thing.
Borowski, on the 15-day disabled list with a strained right triceps, threw the last of his bullpen sessions at Progressive Field on Wednesday. His next step is a simulated outing at Great American Ball Park, when he makes the trip with the team to Cincinnati on Friday.
Assuming he tolerates the simulated session well, Borowski will be ready to go on a rehab assignment. As for how many rehab outings he'll need before he's ready to return to the Tribe and resume his closing duties, that is "yet to be determined," according to head athletic trainer Lonnie Soloff.
Westbrook threw his 70-pitch simulated session on Tuesday. The plan originally called for Westbrook to make a rehab start for Class A Lake County on Saturday, but Soloff said it's possible that start might be pushed back to Sunday. Soloff was still waiting to gauge how Westbrook was feeling from Tuesday's effort.
The Indians won't know how many rehab starts Westbrook will need before he's ready to rejoin the rotation until after they see how he handles the Lake County outing.
