Reagins took over for Bill Stoneman after the 2007 season, rising to the top executive job after starting with the organization as an intern in 1991. Although owner Arte Moreno said “a change was needed’’ in a statement released by the team, Reagins insisted he made the decision to quit after discussing his future with his family over the past month.

“I felt from my perspective that the club probably needed a different perspective and a fresh direction,’’ Reagins said in a conference call. “I felt that Arte wants to win, and at the end of the day, if you perform, you get rewarded. If you don’t perform, you have to be accountable. I felt accountable, because those are the expectations I put on myself. Arte wants a winning ballclub . . . year in and year out.’’

The Angels won the AL West in Reagins’s first two seasons, losing to the Red Sox in the 2008 division series and the Yankees in the 2009 championship series. But Los Angeles has fallen behind the Rangers in the AL West despite a payroll well over $100 million, and Reagins’s record on personnel decisions apparently didn’t please Moreno.

“Though we finished 2011 with a winning record, we remained short of our objective in winning a championship,’’ Moreno said. “In moving forward, we felt a change was needed. Throughout his career, Tony has meant a great deal to this organization, and represented the Angels with the utmost loyalty and dedication. He will always remain part of the Angels family.’’

Team president John Carpino said the Angels have no successor in mind.

“We don’t believe the organization is broken by any means,’’ Carpino said, adding that longtime manager Mike Scioscia will be consulted during the process. “It’s not like somebody has to come in here and rebuild this entire organization.’’

Despite starting this season with baseball’s fourth-highest payroll at $139 million, Los Angeles went 86-76 and finished 10 games behind Texas, and five behind Tampa Bay in the wild-card race.

Ramirez is charged Prosecutors in Fort Lauderdale, Fla., formally charged former Red Sox outfielder Manny Ramirez with domestic violence. Ramirez, 39, was arrested Sept. 12 after his wife told deputies Ramirez slapped her in the face, which caused her to hit her head on the headboard. Ramirez denied hitting his wife.

Ramirez retired in April from the Rays rather than face a 100-game suspension after testing positive a second time for a performance-enhancing substance, although he has since said he wants to return to the major leagues and is willing to serve his suspension.

He is scheduled to be arraigned on the misdemeanor charge Oct. 14.

Baylor hospitalized Diamondbacks batting coach Don Baylor was taken to a hospital after fainting at Miller Park in Milwaukee. Diamondbacks general manager Kevin Towers said Baylor had a “fainting episode’’ after eating breakfast in the clubhouse, and one of the team’s trainers caught him as he fell. Towers said Baylor was taken by ambulance to a hospital, accompanied by members of the team’s medical staff.

“He was a little bit disoriented, so we felt we should get an ambulance here and take him to the hospital,’’ Towers said.

Towers said Baylor, 62, was undergoing tests and the initial results were encouraging.

It was not clear whether Baylor will rejoin the team for today’s Game 1 of the NL division series against Milwaukee.

Braves fire Parrish The Braves are shaking things up after a September flop cost them a second straight trip to the playoffs. The first change came when hitting coach Larry Parrish was fired after only one season. The announcement was a surprise, coming one day after manager Fredi Gonzalez said his entire staff would return. Several hitters regressed noticeably under Parrish, and the Braves finished 13th in the NL in batting (.243) and 10th in runs. Also, Braves general manager Frank Wren also said it’s not certain that 38-year-old Derek Lowe (9-17, 5.05 ERA)will have a spot in the rotation next season, even though the team still owes him $15 million on the final year of his contract.

A’s shake up staff Bob Melvin wasted no time making changes to his coaching staff after receiving a three-year deal last week to stay put as the A’s manager. The Athletics said they aren’t renewing the contracts of bench coach Joel Skinner, pitching coach Ron Romanick, and hitting coach Gerald Perry. First base coach Tye Waller and third base coach Mike Gallego will return, and bullpen coach Rick Rodriguez will be considered a candidate for his same position Melvin took over for the fired Bob Geren in June and went 47-52 the rest of the way, including 35-35 after the All-Star break . . . White Sox closer Sergio Santos agreed to an $8.25-million, three-year contract that includes three club options. Santos, 28, went 4-5 with 30 saves and a 3.55 ERA in 63 appearances this season, and he made a major league-record 25 straight scoreless appearances on the road to start the season from April 2-Aug. 30.
