SCOTTSDALE, Ariz. -- The Giants added another arm into their bullpen mix Wednesday, acquiring right-hander Trevor Gott from the Nationals for cash considerations.
To clear a spot for Gott on the 40-man roster, the Giants moved right-hander Johnny Cueto to the 60-day injured list. Cueto is expected to miss most, if not all, of the regular season while rehabbing from Tommy John surgery.

Gott, who was designated for assignment last week, logged a 5.68 ERA over 19 innings for the Nationals last year. His best season in the Majors came in 2015, when he posted a 3.02 ERA over 47 2/3 innings with the Angels. The 26-year-old has primarily relied on his two-seam fastball, which has helped him induce a 54.3 percent career ground-ball rate in the Majors.
Buster Posey (right hip surgery) enjoyed an unrestricted day as Giants pitchers and catchers took the field Wednesday for their first official workout of the spring. Posey caught Ty Blach and Jeff Samardzija in bullpen sessions, put in some work in the batting cage and took batting practice on the field without issue.
"Really was pretty much a normal day," manager Bruce Bochy said. "Once we get a little closer to games and maybe the workload is picking up with these guys, we will monitor him somewhat. He feels great right now."
Posey's status makes the need for a reliable backup catcher all the more pressing for the Giants, who are holding an open competition for that spot this spring. Rookie Aramís García impressed after being called up in September last year, but he is likely to face stiff competition from Cameron Rupp and René Rivera, both of whom are in camp as non-roster invitees.
Stephen Vogt also joined the Giants on a Minor League deal, though he is coming off shoulder surgery and is unlikely to play in Cactus League games until early March. The Giants are also considering carrying three catchers to start the season.
"I think it's going to be critical that we have coverage," Bochy said. "We're hopeful that all goes well with Buster, we get him back to normal and catching as many games as he normally does, but I do think it's going to be important that we add some depth there. We've got some good names."
Though left-hander Will Smith finished last season as the Giants' closer, there's no guarantee that he'll reprise the role this year. Bochy said he isn't committed to naming a closer yet, noting that right-hander Mark Melancon looks great and appears to be past the forearm injuries that hampered him in the first two years of the four-year, $62 million deal he signed in December 2016.
"We haven't defined the roles yet," Bochy said. "It looks like [Melancon's] getting over the hump with his situation, and he's excited about how he feels."
Cueto has not yet reported to camp due to a personal issue, but Bochy said he is expected to arrive Thursday. Non-roster invitees Jandel Gustave and Carlos Navas are also delayed due to visa issues.
