The St. Louis Cardinals and San Francisco Giants both have interest in free-agent Wei-Yin Chen, according to a report.

Jon Heyman of CBS Sports also writes that the Kansas City Royals and Washington Nationals could become serious suitors.

Over the past two seasons, Chen logged a 3.44 ERA with 6.9 K/9 against 1.8 BB/9 to go along with a 40.8 percent ground-ball rate in 377 innings of work for the Baltimore Orioles.
