OAKLAND -- The A's on Friday pulled in a source of veteran stability for their rotation in right-hander Marco Estrada, who has joined the club on a one-year deal.
The one-time All-Star pitcher will get a guaranteed $4 million, per ESPN's Jeff Passan.
Much like the just-claimed Parker Bridwell, who was outrighted to Triple-A Las Vegas to make room on the roster Friday, Estrada is an intriguing bounce-back candidate following a pair of subpar seasons in Toronto. He posted a 5.64 ERA over 28 starts in 2018 and a 4.98 ERA across 33 outings in 2017, but he averaged a 3.30 ERA in his previous two seasons with the Blue Jays.

The A's are betting on him to regain that form; they've seen it happen with similar candidates in the past under their watch, including Scott Kazmir, Rich Hill and, most recently, Edwin Jackson.
"Last year, he pitched through some back and hip issues and lost a little bit of velocity," A's general manager David Forst said. "But his command is as outstanding as ever. His changeup has always been one of the best pitches in the league. He's a guy we fully expect to bounce back and be near the top of our rotation for 2019."

The A's have stayed in contact with Jackson, who is now a free agent, but it remains to be seen whether the two sides can agree to terms. The addition of Estrada, 35, doesn't preclude the A's from acting again.
Oakland's rotation includes just one other veteran arm in Mike Fiers, who returns on a two-year contract, and little certainty elsewhere. Daniel Mengden, Paul Blackburn, Frankie Montas, Aaron Brooks and Bridwell are in-house options, along with their No. 1 pitching prospect, Jesus Luzardo.
"We're only a couple of weeks from reporting now, so it's hard to say that we'd necessarily get something done," Forst said. "But obviously there are a lot of free agents left out there, and there's still a lot of conversations going on."
Estrada has been extremely durable in his career, and a change of scenery -- to the vast Coliseum, no less -- could do him good, particularly since he's been prone to the long ball. His strikeout numbers have dipped in recent years, while his walk rate has gone in the opposite direction, but the A's obviously feel confident that they can get a ton of innings from him. Few provided that for them last year.
Estrada also brings postseason experience to the table, having compiled a 3-3 record and 2.64 ERA in 10 games -- including six starts -- in October action.
