The Pittsburgh Pirates have agreed to trade All-Star second baseman Adam Frazier to the playoff-contending San Diego Padres for three minor leaguers, a person with knowledge of the deal told The Associated Press.

The person spoke on condition of anonymity Sunday because the deal had not been announced. The trade is pending physicals. Pittsburgh is sending approximately $1.4 million to the Padres in the deal.

Frazier was the National League starter in the All-Star Game this month. He leads the majors with 125 hits and is batting .324. He’ll join a potent Padres infield that includes Fernando Tatis Jr., Manny Machado and Eric Hosmer.

Pittsburgh is receiving infielder Tucupita Marcano, outfielder Jack Suwinski and right-hander Michell Miliano in the swap. The MLB trade deadline is this Friday.

Marcano is San Diego’s No. 5 prospect, according to MLB Pipeline. The 21-year-old shortstop made his big league debut this year, hitting .182 in 44 at-bats with the Padres. He’s hit .272 with six home runs and 26 RBIs in 44 games for El Paso this year.

Suwinski, a 15th-round draft pick by the Padres in 2016, is hitting .269 with 15 homers and 37 RBIs for Double-A San Antonio.
