Scioscia said Skaggs will continue to ramp up his pitch counts in his next few outings as he continues to strengthen the shoulder. He will throw four innings, or 60 pitches, in his next start, followed by five innings or 75 pitches and six innings or 90 pitches.
"He's got a couple more to go, for sure," Scioscia said. "We definitely want to be cautious and make sure that he gets up to a pitch count that his arm is ready for. Hopefully there won't be any setbacks, but he has a lot of work ahead of him."
Skaggs has dealt with a pair of setbacks after undergoing Tommy John surgery in August 2014. He began this season with Triple-A Salt Lake, throwing three starts before being shut down with left shoulder tendinitis. He then threw two simulated starts in Arizona before being shut down again on June 8.
• The Angels will partner with the Anaheim Firefighters Association on Friday for the sixth annual "Fill The Boot" Fundraiser to benefit the Muscular Dystrophy Association of Orange County and Riverside County.

The event will run at Angel Stadium during Friday's game against Oakland, running from 5 p.m. PT through the second inning of the game. There will be stands outside the Diamond Club, Home Plate Gate and Gates 1, 4, 6, 7 and 8.
• Reliever Joe Smith threw a simulated game in Arizona on Wednesday, Scioscia said. He added that Smith will have another workout Sunday, whether it is a rehab assignment or a bullpen session. Smith hasn't pitched since June 4 because of a left hamstring strain.
