Day 2: Deals made, others rumored at winter meetings

• Key developments Tuesday at baseball's winter meetings
• Seattle is working on a contract extension with Felix Hernandez
• Shane Victorino agrees to three-year, $39 million deal with Boston

Key developments Tuesday at baseball's winter meetings:

Red Sox, Shane Victorino agree to three-year, $39 million deal

• What it means: Boston continues to replenish its depleted outfield and adds a center-field alternative in case Jacoby Ellsbury leaves as a free agent after the 2013 season, or perhaps in anticipation of trading him. Victorino brings speed, defense, postseason experience and a bit of pop to the revamping Red Sox.

Nationals, Dan Haren agree to one-year, $13 million deal

• What it means: Haren steps into the starting spot vacated by free agent Edwin Jackson and becomes the rotation's veteran. A starting staff that led the NL in ERA might be better in 2013.

Arizona shopping Justin Upton

• What it means: This is nothing new, as Upton has been trade bait on and off for two years, but the Diamondbacks seem more intent on moving him now. They already traded away his pal and fellow outfielder Chris Young.

Marlins trade Yunel Escobar to Rays

• What it means: Escobar, by far the most expensive ($5 million) of the seven players Miami acquired from the Toronto Blue Jays on Nov. 19, is an established shortstop, The Rays, who used four different shortstops in 2012, were in search of an everyday player.

Mariners working on an extension for Felix Hernandez

• What it means: Rather than breaking up a staff that had the AL's third-best ERA, Seattle wants to build around their 26-year-old ace and seek offensive help via the free agent market.

Rangers weighing Josh Hamilton, Zack Greinke

• What it means: Texas likely can't afford to keep the 2010 AL MVP and also add the 2009 AL Cy Young Award winner, but it continues to explore ways to bolster a team that lost the AL West title on the regular season's final day.

Nick Swisher market developing

• What it means: The Victorino deal only boosts the value for Swisher, who has more power and can play first base. The Mariners and Baltimore Orioles seem to be his most ardent pursuers.
