Diamondbacks GM Dave Stewart joined Mike Ferrin of MLB Network Radio (audio link) to discuss last night’s multi-player deal sending Mark Trumbo to the Mariners. He explained that Welington Castillo (acquired in the deal) was not initially a backstop that had interested him upon taking the helm in Arizona — as he hinted, the club conceivably could have made that move when shipping Miguel Montero to the Cubs — but that the loss of Tuffy Gosewisch forced the team’s hand. “The first guy on my list of catchers was [Dioner] Navarro up in Toronto,” said Stewart, who explained that he “had [him] in my sights even in the winter months, before the Winter Meetings.” Stewart added that prospect Gabby Guerrero, who also comes over in the trade, impressed the club this spring.
That deal is a subject that Steve Adams and I tackle in today’s podcast, which will be available in a few hours. Meanwhile, here’s more from the NL West:
- New Dodgers infielder Hector Olivera will make his professional debut tomorrow at Double-A, Bill Plunkett of the Orange County Register tweets. Director of player development Gabe Kapler had positive things to say about Olivera’s early time in the organization, as Plunkett also reports. “He clearly can handle either” second or third, Kapler added.
- Dodgers closer Kenley Jansen was unavailable last night for unknown and somewhat mysterious reasons, as Mark Saxon of ESPNLosAngeles.com reports. Something apparently occurred during the game itself that changed his status, but what that is has yet to be reported. Meanwhile, four other relievers oversaw a 9th-inning meltdown in Colorado. After the game, the team said that Jansen “wasn’t feeling well, while ESPN’s Rick Sutcliffe tweeted that he was “sending [his] prayers” to the Dodgers and their closer, adding to the intrigue. The outstanding power pitcher has dealt with heart issues in the past, including experiencing an irregular heartbeat while in Denver.
- Diamondbacks outfielder David Peralta has changed agencies and is now a client of ACES, Devan Fink tweeted recently and ESPN.com’s Jerry Crasnick confirms (Twitter link). The 27-year-old has quickly established himself as a solid major leaguer, and owns a .280/.323/.460 slash line in his first 490 plate appearances. With just 120 days of service accumulated last year, he’ll likely not qualify for arbitration until 2018.
