The workload has been heavy this season for Jered Weaver, who ranks second in the major leagues behind Detroit's Justin Verlander with 3,298 pitches and fifth in all of baseball with 2061/3 innings.

But neither the Angels ace nor Manager Mike Scioscia says fatigue or injury is to blame for Weaver's recent struggles.

The right-hander entered August as an American League Cy Young Award candidate, but he has allowed six earned runs or more in three of his last five starts, including Saturday night's shaky five-inning, six-run, eight-hit effort in a 10-6 win over the Twins.

"He wasn't as crisp and his fastball command was off, but he has enough gas in his tank to finish the season strong," Scioscia said. "In talking with him, his arm feels good. Sometimes you're going to be out of sorts."

Weaver, who signed a five-year, $85-million contract extension Aug. 23, slipped on a first-inning pitch Saturday and landed awkwardly on his left foot, but he said that "had nothing to do with" his performance.

"I felt great," said Weaver, who is 16-7 with a 2.49 earned-run average. "I just didn't have my sharp stuff, and they were able to hit mistakes."
