The Twins have designated Esmerling Vasquez for assignment, reports Joe Christensen of The Star Tribune. The move creates room on the 40-man roster for the recently claimed Darin Mastroianni.

Vasquez, 28, was claimed off waivers from the Diamondbacks back in September. He appeared in 31 games for Arizona last year, posting a 4.15 ERA with 5.9 K/9, 3.9 BB/9 and a 35.5% ground ball rate in 30 1/3 innings. The right-hander appeared in 50-plus games for the D'Backs in 2009 and 2010, when he posted higher strikeout rates, walk rates and ERAs than he did in 2011.

The Twins announced that they claimed Darin Mastroianni from the Blue Jays, Danny Knobler of CBSSports.com tweets. The Blue Jays designated the outfielder for assignment last week to create roster space for Francisco Cordero.

Mastroianni made his MLB debut with the 2011 Blue Jays after spending most of the season at Double-A and Triple-A. The 26-year-old posted a .268/.353/.377 line with 34 stolen bases (44 attempts) in the upper minors last year. He has minor league experience at all three outfield positions and has mostly played center field.

The latest minor league deals...

• The Mariners signed former MLB reliever Brian Sweeney to a minor league contract, MLB.com's Greg Johns reports. Sweeney spent the 2011 season with the Mets' top affiliate and last appeared in the Majors with the 2010 Mariners.
• The Twins signed left-hander Luke French, Matt Eddy of Baseball America reports (Twitter links). French owns a 4.99 ERA with 4.6 K/9 and 3.3 BB/9 in 155 Major League innings.
• The Mets signed infielder Matt Tuiasosopo, who picked up MLB experience with the Mariners from 2008-10, Eddy reports.
• The Blue Jays signed right-hander Tim Redding and left-hander Bill Murphy, according to Eddy. Redding has substantial MLB experience as a starter for the Astros, Nationals and Mets.
• Eddy reports that four catchers signed minor league deals: Mitch Canham joined the Rockies, Orlando Mercado agreed to terms with the Marlins, Kyle Phillips caught on with the Blue Jays and Max St. Pierre signed with the Red Sox. Phillips appeared in 36 games for the 2011 Padres and St. Pierre made his debut with the 2010 Tigers after 14 minor league seasons.
• Former MLB starter Daniel Cabrera signed a minor league deal with the Pirates, Mario Rojas of CandelaDeportiva reports. Cabrera, 30, was a fixture in Baltimore's rotation from 2004-08, but hasn't pitched in MLB since 2009.
• The Cubs re-signed infielder Bobby Scales, who started the 2011 season in Chicago before going to Japan, Kevin Goldstein of Baseball Prospectus tweets.
• The Phillies re-signed former Tigers outfielder Brent Clevlen, Goldstein tweets.
• The Orioles signed 18-year-old outfielder Andres Aguilar, Roch Kubatko of MASNsports.com tweets. The speedy Guatemala native has a strong throwing arm.

The Twins and Joel Zumaya have agreed to a one-year contract, the team announced. MLB.com's Jason Beck first reported the deal, which could pay the Hendricks Sports client anywhere from $800K to $1.7MM based on incentives.

Zumaya, 27, told Beck that he was weighing "good offers" from three other clubs, but signed with the Twins because they offered him guaranteed money and not a minor league contract with an invite to Spring Training. The Tigers were not on his short list, and earlier today we learned the Red Sox and Padres were among the clubs with serious interest.

The flamethrowing right-hander has not pitched since June of 2010 due a fracture in his throwing elbow, an injury he suffered at Target Field and the latest ailment in a laundry list of injuries. In the five seasons since his dominant rookie campaign in 2006 (1.95 ERA and 10.5 K/9 in 83 1/3 innings), Zumaya has undergone five surgeries, including two on his elbow, two on his shoulder, and one on his right middle finger.

A Twins official told Phil Mackey of 1500ESPN.com that they clocked Zumaya at 92-94 during his December workout, which was attended by 20 teams (Twitter link). Zumaya hopes join a Twins' bullpen that lost Joe Nathan but will return Matt Capps and Glen Perkins.

Dozens of arbitration eligible players have agreed to deals with their respective teams today and we've been tracking all of the developments right here.  Several teams, including the Rays, Nationals, Marlins, White Sox, Blue Jays, Braves, and perhaps Astros, are known for committing to going to hearings if they get to the point of filing.  Keep track of all the madness with MLBTR's arbitration tracker, which shows settlement amounts, filing figures, and midpoints.  Today's players to avoid arbitration on deals worth less than $4MM:

• The Cardinals avoided arbitration with pitcher Kyle McClellan, tweets B.J. Rains of FOX Sports Midwest. Joe Strauss of The St. Louis Post-Dispatch reports (on Twitter) that the one-year deal is worth $2.5MM with incentives based on starts. MLBTR projected a $2.7MM for the Steve Comte client.
• MLBTR's Ben Nicholson-Smith reports (on Twitter) that the Padres and Chase Headley agreed to a one-year deal worth $3.475MM, avoiding arbitration. Earlier this evening, the Padres announced that they avoided arbitration with Luke Gregerson, Edinson Volquez, Carlos Quentin and Will Venable. They also avoided arbitration with lefty reliever Joe Thatcher on a deal worth $700K, tweets Jon Paul Morosi of FOX Sports.  CAA announced catcher John Baker has signed for $750K.  Bill Center of the San Diego Union-Tribune first reported that the Padres reached agreements with Hundley, Chase Headley, and Tim Stauffer. Hundley will earn $2MM in 2012, MLB.com's Corey Brock tweets.  Dan Hayes of the North County Times tweets the salaries for Volquez ($2.2375MM), Venable ($1.475MM), Gregerson ($1.55MM)
• The Rangers avoided arbitration with Matt Harrison, tweets Evan Grant of The Dallas Morning News. The ACES client gets $2.95MM on a one-year deal. MLBTR had projected a $2.9MM salary.
• The Cubs announced that they have avoided arbitration with Jeff Baker ($1.375MM), Blake DeWitt ($1.1MM), Ian Stewart ($2.237MM) Chris Volstad ($2.655MM), and Randy Wells ($2.705MM). MLB.com's Carrie Muskat tweeted the salary figures.

The Twins avoided arbitration with starter Francisco Liriano, signing the Legacy Sports client to a $5.5MM deal, tweets ESPN's Enrique Rojas.  It was a rough year for Liriano, limiting his raise to $1.2MM.  He'll be a free agent after 2012.

The Twins' arbitration agenda will be complete if they sign infielder Alexi Casilla.

The latest international signings...

• The Twins signed right-hander Mauricio Silva for $370K, Baseball America's Ben Badler reports. The 16-year-old Venezuela native had been considered one of the more promising Latin American pitching prospects to become eligible to sign last summer, Badler writes.
• The White Sox signed Venezuelan right-hander Luis Martinez for $250K, Badler reported yesterday. Martinez, who turns 17 this month, can reach 92 mph on the radar gun and also throws a curveball and change-up, Badler reports. This marks the first major international signing for the White Sox since they hired Marco Paddy from the Blue Jays to oversee their Latin American scouting efforts.

The Twins announced that they signed right-handers Jason Bulger and Casey Fien and infielder Aaron Bates to minor league deals that include invitations to Spring Training. They also announced minor league deals with Phil Dumatrait, Aaron Thompson, Jared Burton, Samuel Deduno, P.J. Walters, Daryl Thompson, Luis Perdomo, Brendan Wise, Matt Carson, Wilkin Ramirez, Sean Burroughs, Steve Pearce, J.R. Towles and Rene Rivera and Spring Training invitations for many minor leaguers in their organization.

Bulger, 33, appeared in five games with the Angels in 2011. He spent most of the season in the bullpen of Los Angeles' top affiliate, where he posted a 4.03 ERA with 11.6 K/9 and 4.0 BB/9. Fien, 28, has MLB experience with the Tigers. He spent the 2011 campaign in the Astros' system, posting a 4.44 ERA with 9.2 K/9 and 2.7 BB/9 in 26 1/3 innings.

Bates appeared in 12 games with the 2009 Red Sox. He spent the 2011 season in the Twins' organization and posted a .316/.408/.439 line at Triple-A. The 27-year-old first baseman/left fielder has a career .378 on-base percentage in the minor leagues.

The Twins announced that they have agreed to sign right-handed starter Jason Marquis to a one-year, $3MM contract. Ken Rosenthal of FOX Sports reported last night that the Twins were nearing a deal with the 33-year-old ACES client.

Marquis made 23 starts for the Nationals and Diamondbacks this past season, finishing the year with a 4.43 ERA in 132 innings. His rate stats (5.2 K/9, 2.9 BB/9, 55.1% ground ball rate) were right in line with his career averages (5.2 K/9, 3.5 BB/9, 50.4% ground ball rate) and his average fastball checked in at 89.3 mph.

Francisco Liriano, Carl Pavano, Scott Baker, Nick Blackburn, Brian Duensing and Anthony Swarzak are options for the Twins' rotation in 2012. Liriano may be able to bounce back from an up-and-down 2011 season, but the Twins will need improvement from others as well if their rotation is to become respectable in 2012. Twins starters finished the 2011 season with a 4.64 ERA (26th in MLB) and 5.8 K/9 (28th in MLB) in 961 innings (21st in MLB).

The Mets also had interest in the New York native this offseason. Marquis signed a two-year, $15MM contract with Washington on this date two years ago the last time he was a free agent.

As MLBTR's Free Agent Tracker shows, Terry Ryan's first offseason back in the GM's office has been a busy one. The Twins have also signed Matt Capps, Jamey Carroll, Ryan Doumit and Josh Willingham this winter. Marquis ranked 45th on MLBTR's list of top free agents this year.

The Twins announced a major signing today, and GM Terry Ryan also stayed busy on the minor league front. The Twins signed Steve Pearce and J.R. Towles to minor league deals, according to Joe Christensen of the Minneapolis Star Tribune (Twitter links). Scott McCauley first reported the Towles deal.

Towles, 27, posted a .184/.256/.293 line in 165 plate appearances with the Astros this past season. His career line is .187/.267/.315, though he picked up just 484 plate appearances over the course of five seasons in Houston. Like Rene Rivera, another recent minor league signing, Towles provides depth behind the plate. Pearce, 28, has MLB experience at all four corner positions. He posted a .202/.260/.255 line in 105 plate appearances for the Pirates in 2011.
