OAKLAND, Calif. (AP) — Experienced closer Trevor Rosenthal reached  agreement on an $11 million, one-year contract with the Oakland Athletics, a person familiar with the negotiations told The Associated Press.

The person spoke on condition of anonymity Thursday because the deal was subject to a successful physical.

“What’s up Oakland?!” the right-hander posted on his Twitter account.

Oakland also reached a $2.25 million, one-year contract with first baseman and designated hitter Mitch Moreland pending a physical, a person with direct knowledge of those negotiations said Thursday. That person also spoke on condition of anonymity because the contract hadn’t been finalized.

The 30-year-old Rosenthal is another new addition to a rebuilt A’s bullpen that general manager David Forst made a priority after Oakland closer Liam Hendriks left as a free agent to sign a $54 million, four-year contract with the Chicago White Sox.

Rosenthal went 1-0 with a 1.90 ERA with 11 saves over 23 2/3 innings for the Kansas City Royals and San Diego Padres last season.

He made $1,510,887 last year, including a $740,741 prorated share of a $2 million base and $770,146 in earned performance bonuses. He also received a $1 million buyout as part of the 2020 mutual option in his previous contract with Washington, which released him in July 2019.

With slugger Khris Davis having departed to Texas in a trade earlier this month, Moreland will have ample opportunities to contribute and get at-bars on an Oakland team that has made the playoffs each of the past three years.

The veteran utilityman, 35, batted .265 with 10 home runs and 29 RBIs in 42 games between Boston and San Diego last season.

He could be a strong candidate to give first baseman Matt Olson a break.

Moreland earned $925,926 in prorated pay last year from a $2.5 million salary.

Oakland also said right-hander Sergio Romo finalized a $2.25 million, one-year deal. The contract includes an additional $750,000 in possible performance bonuses.

He earned $1,759,259 in prorated pay from a $4.75 million salary last year, when he was 1-2 with five saves and a 4.05 ERA in 24 relief appearances for Minnesota. He struck out 23 and walked seven n 20 innings, holding batters to a .211 average. He is 41-34 with 134 saves and a 2.95 ERA, winning World Series titles with San Francisco in 2010, 2012 and 2014.

Reliever Yusmeiro Petit has agreed to a $2.55 million, one-year contract to stay with the A’s, pending a successful physical, his agent said.

Petit was 2-1 with a 1.66 ERA in 26 relief appearances last year, striking out 17 and walking five in 21 2/3 innings. He earned $2,037,037 in prorated pay from a $5.5 million salary.
