Looking at Matt Wieters' market and the top free agents at each position

Now that the Orioles have catcher Welington Castillo to bridge the gap to prospect Chance Sisco, the market for free agent catcher Matt Wieters shrinks again.

Catchers have moved on the market this offseason. The Rays signed Wilson Ramos, the Twins picked up Jason Castro and the Astros, Castro's former team, traded for Yankees catcher Brian McCann. The Diamondbacks didn't offer Castillo a contract and signed Jeff Mathis. The Nationals picked up Derek Norris.

So where does that leave Wieters?

His agent, Scott Boras, says the market will develop in January. Wieters better hope so because for now, the market seems slim.

The hottest speculation is that the Nationals, in need of offense, would make a pitch for Wieters, a four-time All-Star and first-round draft pick who has been Baltimore's catcher since 2009.

The Angels were in need of catcher, but they didn't want to spend money, so instead they traded for veteran Martin Maldonado, a strong defensive catcher. He and 26-year-old Carlos Perez are the Angels' candidates.

The Mets could be in need of a catcher, but only if they think Travis d'Arnoud is an injury risk. The Braves have Tyler Flowers and Anthony Recker and aren't interested in spending a lot of money. And the White Sox, even though they are rebuilding, have a young group of catchers competing for the job.

Now here's a look at the best free agents at each position:

* Right field - Mark Trumbo. The most common prediction at the Winter Meetings was that the teams - and not Trumbo - were in the driver's seat. Apparently, that's coming true. According to MASNsports.com's Roch Kubatko, the Orioles are roughly $30 million apart and have pulled their offer to Trumbo. The Orioles say upgrading the outfield defense is a priority, so we have to assume a Trumbo signing would mean he'd be the full-time designated hitter and the Orioles would still be able to sign another outfielder. Reports say the Rockies want Trumbo for first base, but would they move Ian Desmond from first to the outfield and trade one of their outfielders for bullpen help? Texas is looking for a first baseman and Trumbo could fit there.

* First base - Mike Napoli, 35, hit 34 home runs with 101 RBIs for the American League champion Indians, and the Indians would love to have him back. The Rangers, one of Napoli's former teams, are interested. Another option is Chris Carter, who hit 41 home runs with 206 strikeouts for Milwaukee last season and was non-tendered, being replaced by Eric Thames.

* Second base - At 38, Chase Utley seems destined for a return to the Dodgers unless they can swing a trade for Twins second baseman Brian Dozier, a strong defensive player who can hit 40 home runs. The rest of the field includes Stephen Drew, Gordon Beckham and Kelly Johnson. The Nationals would like to retain Drew as a utility player, but he's looking for a full-time position.

* Shortstop - The top three are Alexei Ramirez, Munenori Kawasaki and Daniel Descalso. Descalso is the youngest at 30. The other two are both 35.

* Third base - Justin Turner got the big bucks when he signed for four years and $64 million with the Dodgers. The best of what's left includes Trevor Plouffe, Erik Aybar and Aaron Hill.

* Left field - The best name out there is 30-year-old left-handed batting Michael Saunders, who hit .253 with 24 home runs with the Blue Jays in 2016. If healthy, Saunders is good. There are also Angel Pagan, Coco Crisp, Noland Reimold and Ryan Raburn. Yoenis Cespedes (Mets), Carlos Gomez (Rangers), Matt Holliday (Yankees DH) and Chris Heisey (Nationals) are the most prominent players signed at this position.

* Center field - There's Rajai Davis, who had 43 steals for Cleveland last season, but how much will teams get from a 36-year-old outfielder? Ben Revere, 28, was non-tendered by the Nationals after being hindered by injuries in 2016 and eventually losing his job to Trea Turner. Michael Bourn is a four-time basestealing champ, but he is a full- or part-time player?

* DH - So far, Evan Gattis (Astros), Kendrys Morales (Blue Jays) and Carlos Beltran (Astros) have signed contracts. The best right-handed bat is Edwin Encarnacion, who will be 34 next season and is experiencing a downward adjustment in the market for power hitters. Encarnacion has 193 home runs in the last five seasons. The best lefty is Pedro Alvarez, who won a National League home run title with the Pirates and then signed with the Orioles last season. Alvarez, 29, adjusted to a part-time duty as a DH. Alvarez was a late sign last spring and could be again this time around.

* Starting pitcher - In a weak market for starting pitchers - did you think that Rich Hill would actually get $48 million? - the two best pitchers left are right-handers Ivan Nova and Jason Hammel. Nova struggled in his development with the Yankees, but found his potential after getting traded to Pittsburgh for the final two months of last season when he posted a 3.06 ERA in 64 2/3 innings. Hammel had a 3.83 ERA last season for the Cubs and made 31 and 30 starts in each of the last two seasons.

* Closer - Aroldis Chapman, Kenley Jansen and Mark Melancon are closers that are going to make in the range of $1 million an inning starting next season. Greg Holland, coming back from elbow surgery, can dominate with a lot less expense if his fastball and slider can return. In 2013-14 for the Royals, Holland had 93 saves and a 1.32 ERA.
