CHICAGO — Derek Holland understands the pivot toward youth by the White Sox and thinks he can thrive in Chicago.

“I wasn’t too concerned. The whole thing is a process,” the 30-year-old left-hander said Wednesday after agreeing to a $6 million, one-year contract. “Whoever is there, I know they’re going to be playing to win.”

Chicago already has traded ace Chris Sale to Boston and outfielder Adam Eaton to Washington. Other deals could be ahead.

While Holland plans to bring his boxer, Wrigley, to Chicago, he’ll leave his five lizards and pet chinchilla at his home in Texas for now.

“You never know what’s going to lie ahead,” Holland said. “Who knows? I could go up there and have an unbelievable year and end up staying with Chicago.”

Holland’s deal includes $2 million in performance bonuses: $1 million each for 150 and 200 innings. He was 62-50 with a 4.35 ERA in eight seasons with Texas, which declined an $11 million option and chose to pay a $1.5 million buyout.

Cubs ink Uehara

CHICAGO — The Chicago Cubs made another addition to their bullpen following the departure of Aroldis Chapman, agreeing to a $6 million, one-year contract with reliever Koji Uehara.

Chicago now has the pitchers who got the final out of three of the last four World Series — Mike Montgomery (this year), Wade Davis (2015) and Uehara (2013). Davis, who figures to take over as closer, was acquired from Kansas City last week for outfielder Jorge Soler.

Uehara spent the past four years in Boston, and the 41-year-old right-hander went 2-3 with a 3.45 ERA and seven saves in 50 appearances last season. He missed about seven weeks because of a strained right pectoral muscle.

Castillo to O’s

BALTIMORE — Free agent catcher Welington Castillo has agreed to a $6 million, one-year contract with the Baltimore Orioles, pending a medical review.

Castillo’s agreement includes a $7 million player option for 2018.

He hit .264 with 14 homers and 68 RBIs in 111 games with Arizona last season, when he made $3.7 million. He is expected to take over from four-time All Star Matt Wieters.
