ANAHEIM -- Left-hander Tyler Skaggs, who missed his scheduled start on Thursday because of right hamstring tightness, will return to the Angels' rotation on Monday and pitch against the Royals in their makeup game at Kauffman Stadium.
Skaggs tested his hamstring during a bullpen session on Saturday and reported no issues afterward. While he was disappointed not to take the mound against the Blue Jays as intended, Skaggs believes it was ultimately a prudent move.
"If I had went out and pitched, it would have been a lot more serious," Skaggs said Sunday. "I've had a lot of injuries in the past. I kind of know when not to push through it. It was tough for me not to be able to go, but at the same time, I thought it was smart."
Skaggs received treatment and played catch on Sunday morning before flying out to Kansas City ahead of the team. The 26-year-old has been the Angels' best starting pitcher this season, logging a 2.81 ERA over a team-high 80 innings. In three starts in June, Skaggs is 3-0 with a 0.45 ERA.
"It's good that Tyler can stay in there because he's been in such a great rhythm," manager Mike Scioscia said.
Restless Trout
Michael Trout started at designated hitter for the fifth consecutive game on Sunday, as he is dealing with a sprained right index finger that hampers his ability to throw in center field. Scioscia said he's sensed some pent-up energy from Trout, who is not used to watching his teammates play defense from the dugout.
"I'm going to tell him today to go out and play catch with the left fielder just so he feels like he can play some defense," Scioscia joked. "Just roll it back left-handed if he can't throw or whatever, because he goes crazy in the dugout."

Trout will be re-evaluated in the coming days before he is cleared to return to the outfield. Chris Young started in center field on Sunday afternoon after missing three games with a hamstring injury.
Robles recalled, Fernandez optioned
The Angels recalled newly acquired reliever Hansel Robles from Triple-A Salt Lake and optioned infielder Jose Fernandez on Sunday. Robles, a 27-year-old right-hander, was claimed off waivers from the Mets on Saturday. He posted a 5.03 ERA over 19 2/3 innings for the Mets this year before being designated for assignment.

Injury updates
• Right-hander Garrett Richards (left hamstring strain) continues to improve and is progressing towards throwing a bullpen.
• Infielder Zack Cozart (left shoulder subluxation) has resumed hitting on the field and taking ground balls, though "he's still got a little work to do" before he's ready to return, Scioscia said.
