CHICAGO (AP) Star closer Aroldis Chapman joined the Cubs on Tuesday, arriving to a mixed reaction in Chicago and saying he couldn't remember what management told him about off-field expectations and behavior.

When the Cubs announced the trade with the New York Yankees on Monday, the team released a statement from Chairman Tom Ricketts saying they were aware of his 29-game suspension to begin the season under Major League Baseball's new domestic violence policy.

Ricketts said he and president of baseball operations Theo Epstein talked by phone with Chapman before the deal was completed and ''shared with him the high expectations we set for our players,'' adding that Chapman was ''comfortable'' with them.

But when asked repeatedly about that phone conversation before Tuesday's game against the crosstown White Sox, Chapman said through an interpreter that he couldn't recall details because he was taking a nap at the time the call came in.

The question was asked several more times. A Cubs spokesman once asked the question himself to the interpreter, coach Henry Blanco.

''It's been a long day,'' Chapman said. ''Trying to remember.''

Asked again several minutes later during the group interview if he could now remember what Ricketts said, Chapman shook his head.

''I still don't remember,'' he said in Spanish.

Chapman was accused of choking his girlfriend and firing eight gunshots in the garage of a Florida home in October. The woman later changed her story and no charges were filed.

''You learn from the mistakes that you make,'' Chapman said.

The case caused the Los Angeles Dodgers to back out of an offseason trade for Chapman. Cincinnati eventually traded him to the Yankees, and after his suspension the 28-year-old Cuban converted 20 of 21 save chances for New York.

The Cubs have long boasted of stocking their roster with high-character players, helping earn the ''lovable losers'' label they've carried for decades since their last World Series title in 1908.

But the Cubs (59-39) have retooled their roster under Epstein and entered Tuesday with the best record in the major leagues. Chapman, who threw a 105 mph fastball earlier this season, fills perhaps the team's largest hole as he replaces Hector Rondon as closer.

The Cubs sent four players to the Yankees, including shortstop prospect Glibber Torres, to get one of the game's top relievers. Epstein said they wouldn't have made the deal if not for the phone call with Chapman.

The Cubs activated Chapman before Tuesday's game and designated left-hander Clayton Richard for assignment.

Reaction to Chapman's acquisition in Chicago has been tepid. While there were supportive fans on talk radio, the Chicago Tribune carried a front-page column Tuesday criticizing the move. The back of the Chicago Sun-Times tabloid read ''Spin City'' over a picture of Epstein.

Chapman said he expected a ''good reaction'' from Cubs fans. He was also asked during the 20-minute meeting with reporters in the visiting dugout at U.S. Cellular Field if we would consider working with organizations looking to prevent domestic violence. Chapman said no.

Cubs manager Joe Maddon defended Chapman.

''We've all been less than perfect,'' he said.

Chapman said he wrote the statement released by the team Monday that said he was sorry for the off-season incident.

''I'm a better person now,'' he said.
