Bronson Arroyo will turn 37 in the early stages of spring training, but that hasn't dissuaded the Twins from calling to express preliminary interest in the free-agent right-hander.

According to a person with direct knowledge of the situation, the Twins have yet to make a formal offer for Arroyo, who has thrown between 199 and 240 innings for nine straight seasons, but the interest seems to be mutual.

The durable veteran has averaged 13.2 wins and 210 2/3 innings in that span, which dates to his final season with the Boston Red Sox. Twins special assistant Wayne Krivsky was the one who brought Arroyo to Cincinnati in March 2006, six weeks into his tenure as Reds general manager, sending outfielder Wily Mo Pena to Boston in a two-player deal that proved very one-sided.

The Reds did not make a qualifying offer to Arroyo, who recently completed a three-year, $35 million contract and has a career earned run average of 4.19. He has averaged $12 million in salary over his past five seasons and is coming off a 14-12 season with a 3.79 ERA.

Right-hander Phil Hughes and left-hander Jason Vargas also have drawn preliminary interest from the Twins, according to a different source.

Hughes, 27, is the youngest domestic starting pitcher on this year's free-agent market. He went 4-4 with a 5.19 ERA this year for the New York Yankees, but the pronounced fly-ball pitcher has performed much better in recent years away from Yankee Stadium.
