PHOENIX -- When thinking about his career, outfielder Kyle Lewis likens himself to an author.

"You just keep writing chapters in a book, and you never know what those are going to look like," he said.

In 2023, Lewis will open a new career chapter after being acquired from the Mariners last month in exchange for catcher/outfielder Cooper Hummel.

Lewis, who won the 2020 American League Rookie of the Year Award with Seattle, gives the D-backs a right-handed bat to help balance out their lefty-heavy outfield. Injuries to his right knee have limited Lewis the past two seasons, but Arizona is confident he is healthy.

"We felt like he was a good fit for us," D-backs GM Mike Hazen said. "We're taking a shot at some upside here with the power potential. He’s gotten on base when healthy and we feel like this is a good opportunity for us acquire some potential impact. He seems like he’s healthy right now, finished the season healthy."

Lewis said the biggest challenge for him will be figuring out the ins and outs of the D-backs' organization. After the trade, one of his biggest questions was who he needed to call about using the batting cage at the team's Spring Training facility and who he needed to contact about offseason conditioning.

"Those guys did a great job reaching out early and being proactive, too," Lewis said. "So that really eased it right there, and then they made me feel comfortable right away. So I talked to [manager Torey Lovullo] and a few other guys on the staff."

One thing Lewis will not have to do is find a new place to live. He had bought a house in Arizona so that he would have a place to stay and train during the offseason. Now, he can live in it year-round.

"When the trade went down, we were pretty excited about it," Lewis said. "It was kind of a surreal moment. It's like, 'Dang, I can stay in my house all year.' So it was cool."

D-backs add Castro to bullpen
In other news on Friday, the D-backs signed free-agent right-hander Miguel Castro.

Castro, who will turn 28 later this month, was 5-0 with a 4.03 ERA in 29 innings spread over 34 relief appearances for the Yankees last season. A right shoulder strain landed him on the 60-day injured list, but he returned to throw a couple of innings in the season's final week as well as in the AL Championship Series.

Control has been an issue at times for Castro -- he walked 15 batters in 29 innings in 2022 -- but he also has an outstanding fastball that averaged 98 mph this past season.

The D-backs have made adding power arms to their bullpen a priority this offseason. In addition to Castro, they acquired right-hander Carlos Vargas from the Guardians last month.
