• Displaced Angels starter Hector Santiago was charged with five runs on eight hits in 2 2/3 innings in his first start for Triple-A Salt Lake on Sunday, walking four and striking out one. Angels pitching coach Mike Butcher said the 26-year-old left-hander was "erratic."
"It's a work in progress," Scioscia added. "He's not just going to snap back into it."
• Left-hander Wade LeBlanc -- called up from Triple-A Salt Lake on Sunday -- wasn't listed on the Angels' lineup sheet on Monday, a strong indication that he's in line to take the ball in Thursday's series finale in Seattle. That, however, could hinge on whether or not he's needed out of the bullpen before that.
• Butcher was encouraged by De La Rosa's Sunday outing for Triple-A Salt Lake, when he needed just six pitches -- five of them strikes -- to pitch a 1-2-3 inning that included a strikeout. De La Rosa's fastball velocity sat mostly at 92 mph. It was the 31-year-old right-hander's third outing since returning to his rehab assignment.
