The holiday lull is officially over. Last Thursday night the Angels signed catcher Jason Castro and the Nationals inked setup man Will Harris. Fourteen of our top 50 free agents remain unsigned, including four of the top 15. There are also more than enough trade candidates to go around, especially relievers

With that in mind, here are Monday's hot stove rumors. Make sure you check back throughout the day for updates.

Rangers among finalists for Castellanos

The Rangers have prioritized pitching this offseason. First, they signed Kyle Gibson and Jordan Lyles to multi-year contracts; then they traded for Cleveland ace Corey Kluber. Now, the Rangers appear to be interested in adding to their lineup -- and that just might mean landing outfielder Nicholas Castellanos

The Rangers recently had a meeting with Castellanos, and they are considered to be one of the finalists for his services, per Jon Morosi of MLB.com. Castellanos appeared to be on track for a one-year deal prior to a deadline trade that sent him to the Cubs. From that point onward, he hit .321/.356/.646 (151 OPS+) with 16 home runs and 21 doubles in 51 games.

Castellanos would presumably fill a corner-outfield spot, or perhaps even first base for the Rangers. He's considered a substandard defender, albeit one with better-than-advertised athleticism. The Rangers currently have Ronald Guzman at first base.

Angels discuss Clevinger

The Angels originally drafted Mike Clevinger before later trading him to Cleveland in exchange for Vinnie Pestano. Now, with the Angels seeking rotation help, a reunion could be in store.

The Angels have checked in with Cleveland on Clevinger, per Jon Morosi of MLB.com. Morosi adds that talks haven't been active in recent days, and that Cleveland requested top prospect Jo Adell and more in return. Obviously the Angels are reluctant to meet that ask. Here's more on the state of the Angels' trade chips.

The Dodgers and Padres have also been connected to Clevinger this winter. Cleveland has a difficult decision to make over the coming weeks as it pertains to retaining both Clevinger and star shortstop Francisco Lindor

Orioles sign Iglesias

Last season, the Orioles permitted Rule 5 pick Richie Martin to slog through a poor season at shortstop. That won't be the case in 2020, as the Orioles agreed to terms with veteran Jose Iglesias on Monday, per MLB.com's Mark Feinsand. Iglesias will receive $3 million as part of a contract that includes a club option.

Iglesias is an above-average defender who has posted an 86 OPS+ over the last two seasons. That number, modest though it may be, would've tied for the seventh-best mark on the 2019 Orioles.

Nationals sign Hudson, Thames

The Nationals have re-signed reliever Daniel Hudson to a two-year deal and signed slugger Eric Thames to a one-year contract. Hudson, who recorded the last out in the World Series, pitched well after arriving in D.C. at the trade deadline. He had a 1.44 ERA and a 5.75 strikeout-to-walk ratio in 25 innings. Hudson has a lengthy injury history and hasn't been quite as good in other recent seasons, suggesting he's more likely to be a useful middle reliever over the life of the deal than a fire-breathing closer. Thames has been a steady source of power against right-handed pitchers the last three years and a useful bench bat/platoon first baseman.
