The Royals made the biggest move of the day on Thursday, bolstering their starting rotation by signing free-agent left-hander Jason Vargas to a four-year, $32 million contract. Vargas, who will turn 31 in February, went 9-8 with a 4.02 ERA last season for the Angels, who now have another hole to fill on their staff.
Meanwhile, Wednesday night's big trade between the Rangers and Tigers continued to hold the baseball world's attention. The swap of Ian Kinsler and Prince Fielder could have far-reaching implications. Among them:
• The trade gives the Tigers additional financial flexibility they could use to pursue contract extensions for Max Scherzer and/or Miguel Cabrera, writes MLB.com's Jason Beck. There also is the issue of how Detroit will adjust defensively, with Cabrera likely shifting to first and opening up a spot at third that could be filled by top prospect Nick Castellanos.
• The ripple effects from the deal could surface in Cincinnati, says MLB.com's Mark Sheldon, impacting the Reds' potential plans to move second baseman Brandon Phillips.
• Kinsler's departure from Texas likely eliminates the possibility of the Rangers parting with Elvis Andrus. That gives the Cardinals one fewer option in their pursuit of a shortstop, as MLB.com's Jenifer Langosch explains.
In other news from around the league on Thursday:
• The Tigers moved quickly to their next order of business, re-signing lefty Phil Coke to a one-year deal to avoid arbitration.
• The Giants have agreed to a deal to keep left-handed specialist Javier Lopez in San Francisco, with multiple reports indicating he will receive a three-year contract.
• The Angels and Cardinals have discussed a swap that would send third baseman David Freese to Anaheim in exchange for an outfielder, such as Peter Bourjos.
