SAN DIEGO -- The holiday season marks the halfway point of the offseason, and this year, the Padres will be just as busy in the second half as they were in the first.
The Winter Meetings proved eventful, as San Diego landed Chase Headley and Bryan Mitchell from New York, while parting with Ryan Schimpf and Jabari Blash. But there's still plenty of work left for general manager A.J. Preller.
• Meetings set up Padres for busy offseason

It's been eight weeks since the World Series, and eight weeks remain until the start of camp. Here's a look at what the Padres have already accomplished this offseason, and what's still on their agenda.
WHAT THEY'VE DONE
Added pitching:Colten Brewer, Jordan Lyles, and Bryan Mitchell -- welcome aboard. Matt Strahm, Colin Rea and Robbie Erlin -- welcome back from injury. The Padres' biggest need this offseason was always pitching, and they've clearly begun to address it. With Lyles and Mitchell in the fold (and the three injured starters returning), the Padres have eight pitchers who will compete for a place in the rotation. Brewer, meanwhile, a former Yankees farmhand, appears ticketed for a place in the bullpen.
Traded for a shortstop: After going the free-agent route in each of the past three years, the Padres broke with recent tradition and traded for a shortstop: Former Phillie Freddy Galvis, who should be a major defensive upgrade. It cost the Padres Enyel De Los Santos, a hard-throwing righty prospect. But San Diego believes in Galvis' glove and has received rave reviews about his impact in a young Philadelphia clubhouse. Plus, there's a chance Galvis re-signs in San Diego next offseason, though he'd likely need to take on more of a utility role with prospect Fernando Tatis Jr. nearing the big leagues.

Created an overflow of infielders: There was already a glut of infielders in San Diego, before the Yankees landed Headley on Day 2 of the Winter Meetings. Now, it's practically a lock that someone gets dealt. The Padres have Headley, Yangervis Solarte, Carlos Asuaje and Cory Spangenberg for two spots at second and third base. It's no longer a matter of "if" the Padres will deal an infielder, but "when."
WHAT'S LEFT TO DO
Add more pitching: The Padres have added three arms to their 40-man roster this offseason -- which means they're about halfway done, given that Preller noted a preference to have 10 starters competing for rotation places. Expect him to add one or two more options. Plus, he'll need to replace Craig Stammen (quietly one of the most effective middle-inning relievers in the National League last year) in the bullpen.

Sign a candidate for backup catcher:Rocky Gale and Raffy Lopez will likely get the chance to compete for the backup catcher job in San Diego, but that doesn't mean they're going to be the only competitors for the role. Before camp, the Friars expect to add another option to play behind Austin Hedges -- preferably a veteran. But Hedges will continue to receive the bulk of the playing time.
Trade an infielder (or two): Here's where things get tricky. Headley -- and his one-year, $13 million deal -- seems the likeliest to be flipped. But Solarte might fetch the most value, given his experienced bat, his versatility and his team-friendly contract. Of course, trading Solarte means the Padres would need to find a serviceable backup shortstop. That leaves Spangenberg and Asuaje as trade options, but the Padres won't part with young, controllable talent for cheap. They'll line up offers for all four and pick the best one (or maybe even two, if the deals are good enough).
