The offseason marches on, and thanks to a relatively slow winter meetings we've got plenty of big names still on the board. To give you an idea of the buzz that's out there on Tuesday, we're here to round up all the notable trade and free agency rumors. As always, our Free Agent Tracker is a great way to catch up on what's already happened on that front

We'll continue updating throughout the day. 

Now let's jump in ... 

Astros in mix for Realmuto

With the Astros having signed Michael Brantley on Monday night to play left field, they might feel freed up to deal top outfield prospect Kyle Tucker. As such, check this out: 

Adding J.T. Realmuto to the Astros' already-potent offense would be amazing. As reported there, though, the Padres, Dodgers and Rays remain interested in the All-Star catcher. 

Realmuto hit .277/.340/.484 with 30 doubles and 21 homers in just 125 games last season, posting relatively gaudy 4.3 WAR in that time. He's only under team control for two more seasons and it's hard to see the Marlins being competitive within that window, so it makes all the sense in the world to trade him now like they did Giancarlo Stanton, Marcell Ozuna, Christian Yelich and more last offseason. 

Daily Harper, Machado update!

Contrary to previous reports, Jon Heyman says that the Phillies did indeed meet with Bryce Harper's agent Scott Boras during the winter meetings in Las Vegas and that they remain in on Manny Machado. The Phillies aren't the only team looking at both, as Heyman says the White Sox are still pursuing both of the top available free agents. (More on the White Sox's hot stove pursuit of those superstars here from our Jonah Keri.)

All the other teams seemingly involved have chosen one or the other, such as the Yankees with Machado and Dodgers with Harper. Several teams remain on the periphery, but the list for both really does seem pretty short right now. 

Then again, remember when Boras convinced the Tigers to sign Prince Fielder out of the blue in the middle of January? It's hard to really narrow the field here on either until there's something definitive. 

Cubs sign Descalso

The Cubs have signed utility infielder Daniel Descalso to a two-year, reported $5 million deal. They now have tons of infield depth. Full story here

Royals sign Gore to MLB deal

The Royals are stocking up on team speed. They already added Billy Hamilton and Tuesday announced they were bringing back basepath terror Terrance Gore. He's mostly been a minor-leaguer and September call up to serve as a pinch runner, but the Royals announced his deal is a major-league deal. 

In 63 career games, Gore only has 19 plate appearances. He's 1-for-19 (the hit came off Max Scherzer because baseball is awesomely weird), but he's also 27-of-31 career in stolen base attempts. He's scored 19 runs. In postseason play, he's been successful on five of his six stolen base attempts with three runs scored. 

Giants interested in Troy Tulowitzki

The San Francisco Giants are among the teams with interest in free agent infielder Troy Tulowitzki, Jeff Passan of Yahoo Sports reports. Tulowitzki was released by the Toronto Blue Jays earlier this month with two years and $38 million left on his contract. Giants' president of baseball operations Farhan Zaidi and manager Bruce Bochy were both in attendance at Tulowitzki's open workout on Tuesday.

The Giants will have competition if they want to pick up the veteran shortstop. The San Francisco Chronicle's Susan Slusser recently tweeted that at least six teams are considering Tulowitzki. The Pirates, Cubs and Yankees are among those reported to have at least cursory interest in Tulowitzki. 

Tulowitzki, 34, appeared in just 66 games in 2017 and missed all of last season following surgery to remove bone spurs from both of his heels. From 2015-17, he hit .263/.322/.429 (97 OPS+) while averaging 16 homers and 108 games. 

Matt Harvey, Angels reportedly agree to one-year

The Los Angeles Angels have agreed to a deal with free agent starter Matt Harvey, according to Mark Feinsand of The deal is for one-year and $11 million, per The Athletic's Ken Rosenthal. Harvey could end up making as much as $14 million next season with performance bonuses, reports Jeff Passan of Yahoo Sports.
