The Sox received right-hander Simon Castro and lefty Pedro Hernandez, neither of whom has appeared in the big leagues.
Castro, 23, went 7-8 with a 5.63 ERA in 22 starts between Classes AA and AAA. He is 29-33 in six seasons in the Padres’ organization.
Two seasons ago, Castro not only started the minor league All-Star Futures Game, but was named Padres pitcher of the year while going 10-6 with a 3.33 ERA.
“That’s behind him and I look forward to seeing him up close and in person,” Williams said.
Hernandez, 22, went 10-3 with a 3.49 ERA in 28 games at three different minor league levels. He has split time between starting and relieving and was named to the Class A California League All-Star team after going 5-0 with a 2.70 ERA in 15 games.
Hernandez is 25-11 with a 3.55 ERA in 93 games, 48 of them starts, in five minor league seasons.
Quentin played in just one of the Sox’s final 37 games because of a shoulder injury. But he did reach the 20-homer mark for the fourth straight season and made his second All-Star game.
In four injury-plagued seasons with the Sox, Quentin hit .257 with 107 homers and 320 RBI in 478 games.
His place in right field is expected to be taken by Dayan Viciedo.
