ANAHEIM, Calif. (AP) — Los Angeles Angels first baseman Trey Mancini, a cancer survivor and former Baltimore slugger, played in his first major league game since 2023 on Monday night against the Houston Astros.
Mancini delivered a run-scoring single in the second inning in his first at-bat.
The Angels selected the contract of Mancini and put him in the lineup at first base against the Astros after placing infielders Vaughn Grissom (left oblique strain) and Adam Frazier (right elbow inflammation) on the 10-day injured list.
Mancini, 34, agreed to a minor league contract with the Angels in February, a deal that included an invitation to major league spring training. Mancini hit .273 with six homers, 29 RBIs and three steals for Salt Lake this year.
Mancini has batted .263 with 129 homers and 400 RBIs over parts of seven seasons in the majors. He played parts of six seasons with the Orioles and hit a career-high 29 homers in 2019.
Mancini then missed the 2020 season after surgery to remove a malignant tumor from his colon. He made a successful return to the Orioles in 2021, and he won a World Series ring in 2022 after Baltimore traded him to Houston.
He spent part of the 2023 season with the Chicago Cubs. He has since played in the minor league systems of the Reds, Marlins and Diamondbacks.
Mancini opted out of a minor league deal with Arizona last July after batting .308 with 16 homers for Triple-A Reno.
Grissom’s move to the IL was retroactive to Friday. Frazier’s move was retroactive to Saturday.
The Angeles also recalled infielder Denzer Guzman from Triple-A Salt Lake and transferred infielder Yoán Moncada to the 60-day injured list.

Three more cases of the New World screwworm have been confirmed, including one outside the main cluster in Texas, demonstrating the difficulty of stopping a resurgent pest that could devastate the nation's cattle industry, the U.S. Department of Agriculture announced Monday.
The screwworm is actually a fly larva that eats living flesh instead of dead material. The flies lay their eggs in open wounds of animals like cattle, but wildlife, pets and occasionally even humans can be infested. The government has a program to breed sterile male flies and drop swarms of them from planes to mate with wild females, which kept screwworm contained at the southern end of Panama for decades.
So far, there are five confirmed cases: three calves and a goat in Texas and a dog from neighboring Lea County, New Mexico. The small dog, which the USDA initially reported as a Texas case, lives in New Mexico and was reclassified as the first in that state.
The dog had not traveled to Mexico or Texas, so authorities were investigating around the property where the pet lived. If they find infected flies, animal inspections in the area will increase, New Mexico State Veterinarian Samantha Holeck said during a virtual news conference Monday.
The first two screwworm cases were discovered last week in calves a few miles apart in south Texas. A case was announced Monday in a calf in La Salle County, southwest of San Antonio, and in a goat in Gillespie County, west of Austin.
In each case, officials have set up a 12-mile (20-kilometer) quarantine zone to try to slow the parasite's advance.
Along with cattle and other warm-blooded livestock, scientists worry screwworms could devastate the millions of wild white-tailed deer in Texas.
Scientists expect new cases could pop up in the coming days and weeks, but it doesn't mean screwworm is spreading rapidly, said Edward Burgess, a University of Florida entomologist who studies the fly.
“When that first case is seen, everyone is being vigilant and their eyes are on it more intensely,” Burgess said. “And when you are looking for something, you are more likely to see it.”
Screwworm gets its name from the maggots’ habit of burrowing — or screwing — into a wound, according to the USDA. The pest eats the flesh of the animal, further opening wounds and increasing the risk of deadly bacterial infections. Animals can die within a few weeks if not treated. There are a dozen government-approved medications to treat livestock.
The agency and the U.S. cattle industry have been racing to prevent an outbreak since screwworm was detected in Mexico late in 2024. The USDA has been dropping sterile flies in south Texas since February and is working to both increase sterile fly production in plants outside the U.S. and build a $750 million fly factory in Texas.
So far, screwworm's reappearance hasn’t greatly affected beef prices, which are already near record levels because there are fewer cows in the United States. Although the parasite attacks live cattle, it does not infest meat or fruit.
Canada temporarily stopped importing cattle, horses or other livestock from Texas on Friday. The parasites prefer humid areas where temperatures are at least 77 F (25 C), making them more of a summer problem up north.
Burgess said the long-term solution — breeding sterile male flies — is months away. Since wild female flies mate just once, if that encounter is with a sterile male, outbreaks can eventually be halted as the flies die out.
The goal is to have enough sterile flies to stop the pests from returning in 2027 after the winter kills off most of them, USDA Secretary Brooke Rollins said at a news conference at the U.S. Livestock Insects Research Laboratory in Kerrville, Texas.
Scientists are also working on ways to sterilize only male flies to make the program even more effective.
Texas officials encouraged ranchers to keep a close eye on their herds and local wildlife. There's now a 24-hour screwworm hotline and a website and map for reported cases.
“This is a highly treatable condition if you act on it immediately,” Republican Gov. Greg Abbott said.
However, Texas Agriculture Commissioner Sid Miller — who lost the recent Republican primary to a candidate backed by Abbott — said the federal response will take too long and risks crippling the cattle industry.
Instead, he says a poison bait could eliminate the screwworm problem in a few months, even if the USDA and other experts say the bait hasn’t been proven effective and could poison other flies, animals and even humans.
“What the hell is a good fly?” Miller said in an interview.
This story has been updated to reflect that the USDA revised the dog screwworm case to New Mexico, not Texas as the agency initially reported, and to correct the spelling of Kerrville.
