Scioscia said Guerrero has been fighting the stomach problem for a couple of days. Guerrero might be available to pinch-hit on Wednesday, according to his skipper, but that will depend on how he's feeling.
"He should be good to go on Friday," Scioscia said. "We'll try to get some fluids back into him, and he should be fine."
The best part of Escobar's outing, however, might have been the pitcher's velocity. Out since Spring Training with a torn right labrum, Escobar ran his fastball up around 95 mph -- he generally throws around 93.
"He did really well," Scioscia said. "Great velocity,"
Scioscia said the next step is to have Escobar meet the team in Los Angeles for evaluation. If everything checks out, he should be ready to go out on a rehab assignment with the Class A Rancho Cucamonga Quakes.
"Right now the plan is he'll pitch Monday with Rancho," Scioscia said, adding that Escobar would go at least 45 pitches in that outing.
Scioscia also said that injured reliever Chris Bootcheck (strained right forearm), who threw a 30-pitch simulated game on Wednesday, could head to the Arizona Summer League in a couple of days.
