Lincecum started nine games for the Angels, recording a 2-6 record with a career-worst 9.16 ERA.
Angels manager Mike Scioscia spoke with the media about the decision, per Moura: “It’s very clear now that he hasn’t progressed from his first couple starts. He’s kind of regressed a little bit.”
Jeff Fletcher of the Orange County Register reported that Lincecum has accepted his assignment to Triple-A Salt Lake and that it's unclear whether he will start or move to the bullpen.
The 32-year-old started his Angels career in impressive fashion on June 18, going six innings against the Oakland Athletics while allowing just one run on four hits.
In his following eight starts, he allowed three or more earned runs in each appearance, including a 1.1-inning effort against the Houston Astros on July 24 in which he allowed eight earned runs on seven hits.
His latest start Friday night against the Seattle Mariners wasn't much better, as the M's tagged him for six runs and nine hits in 3.1 innings.
The writing was on the wall when Scioscia was asked if Lincecum would make another start after Friday's game.
"So, if you ask me right now, I could say 'yes,'" the manager said, per Moura. "But, obviously, we have to sit down, review his video, see where the positives were and see where we are."
Lincecum began the season as a free agent while he recovered from the hip surgery he underwent in September.
It was an unceremonious ending to his time with the San Francisco Giants, with whom he won a pair of Cy Young Awards. He saw his play dramatically decrease over the past few seasons as he compiled a 39-42 record from 2012 to 2015.
Given Lincecum's struggles, he'll likely go unclaimed on waivers. If that's the case, he will have to hope another team is willing to give him a chance to prove he can rediscover the form that made him one of the best pitchers in the game five years ago.
