ST. PETERSBURG, Fla. \u2014 The Chicago White Sox will look to lean on Luis Castillo\u2019s vast experience after acquiring the right-hander Saturday night in a trade with the Seattle Mariners.<\/p>\n
\u201cHis reputation within the league is excellent,\u201d Sox general manager Chris Getz said during a videoconference call on Sunday. \u201cThe leadership qualities, the type of teammate that he is, the work ethic. Someone that is not going to be scared, is a fearless competitor.<\/p>\n
\u201cThe amount of people that I talked to regarding what he brings to the table in terms of being the competitor and the person, it was about as glowing as I\u2019ve heard about any player. And then you put that into the impact that it can have on just the entirety of this team, this pitching staff, it just became more and more attractive. And really happy that we were able to get this deal done.\u201d<\/p>\n
The Sox sent reliever Seranthony Dom\u00ednguez along with minor-league outfielder Nolan Jones and catcher Boston Smith and conditional cash considerations to Seattle to complete the deal.<\/p>\n
\u201cReally excited about Castillo, a guy who\u2019s had a lot of success in this league for a long time,\u201d Sox manager Will Venable said.<\/p>\n
Castillo, 33, is 3-9 with a 5.06 ERA in 20 outings (17 starts) this season. He has 86 strikeouts and 32 walks in 99 2\/3 innings.<\/p>\n
He is 87-93 with a 3.65 ERA in 263 career outings (260 starts) over 10 seasons with the Cincinnati Reds (2017-22) and Mariners (2022-26). Castillo\u00a0has 1,579 strikeouts in 1,510 1\/3 career innings.<\/p>\n
Castillo earned All-Star honors in 2019, 2022 and 2023. He finished fifth in the American League Cy Young Award voting in 2023.<\/p>\n
Castillo has playoff experience, posting a 2.25 ERA in six career postseason games (five starts).<\/p>\n
\u201cI know that they\u2019ve been playing pretty good baseball here lately,\u201d Castillo told reporters covering the Mariners through an interpreter. \u201cI\u2019m going to come in, be the new guy. And kind of when you\u2019re the new guy, you\u2019ve got to start from zero. Getting to know all the personnel, getting to know everybody.<\/p>\n
\u201cJust got to stick to my routine and just keep doing what I\u2019ve been doing here.\u201d<\/p>\n
\u201cThis was an opportunity to bring in a starting pitcher that we\u2019re really excited about,\u201d Getz said. \u201cSomeone that can help lead this young pitching staff. Not only cover innings, but has experienced pitching in the playoffs.\u201d<\/p>\n
As of Sunday afternoon, the Sox were still working through the plan of when Castillo would make his debut. With his addition to the rotation, the Sox will shift Erick Fedde into a bullpen role.<\/p>\n
\u201cLuckily I have those experiences in my career,\u201d Fedde said. \u201cIt\u2019s one of those things you\u2019ve got to be a little more focused on prep and make sure you keep yourself in a good position. They are keeping me stretched out, so it\u2019s not going to be something like where I\u2019m throwing three days around. It shouldn\u2019t hopefully be too bad.\u201d<\/p>\n
The Sox traded away a bullpen arm in Dom\u00ednguez. The right-hander went 4-3 with a 3.99 ERA and 12 saves in 43 outings for the Sox. He signed a two-year deal<\/a> with the team in the offseason and spent a portion of the season as the closer. Dom\u00ednguez went through a rough patch but has been better of late.<\/p>\n \u201cMade an incredible impact on the field, and in the clubhouse,\u201d Venable said. \u201cJust really appreciated everything that Seranthony did for us.\u201d<\/p>\n The Sox acquired Jones in a trade with the Cleveland Guardians in June. He hit .227 with six home runs and 28 RBIs for Triple-A Charlotte after the deal. Jones has a .247 average with 30 home runs and 137 RBIs in 349 major-league games over four seasons with Cleveland (2022, 2025) and the Colorado Rockies (2023-24).<\/p>\n
