Instead of moving forward as scheduled on Friday, Westbrook only threw on flat ground. Afterward, he reported feeling much better than he had the day before.
Westbrook has already missed two starts due to a right oblique strain. His hope was that he would be cleared to return after throwing a second bullpen session. Westbrook said this one-day setback hasn't changed that expectation.
If Saturday is indeed the last step in the right-hander's recovery, the Cardinals could plug Westbrook into the rotation during the team's three-game series in Houston, which begins on Monday.
Because Westbrook's status remains fluid, the Cardinals have not announced their rotation beyond this weekend. Every expectation is, though, that Lance Lynn will stay on turn and pitch Monday's series opener. Lynn threw his scheduled in-between starts bullpen session on Friday.
