Talks between the Twins and veteran right-hander Bronson Arroyo are heating up. Negotiations had yet to commence as of Tuesday evening, according to a person with direct knowledge, but the Twins have been going over Arroyo's medical records and have discussed guarantee language with his representatives while in Orlando for baseball's General Managers' Meetings. Arroyo, who has thrown between 199 and 240 innings for nine consecutive seasons, will be 37 on Opening Day. That would make him the oldest member of the Twins' pitching staff, as presently constituted. Right-hander Kevin Correia, who led the Twins with 31 starts and 185 1/3 innings last season, is 33. Widely valued for his durability and leadership, Arroyo is coming off a season in which he went 14-12 with a 3.79 earned run average for Cincinnati. Arroyo did not receive a qualifying offer from the Reds after winning 105 games for them over the past eight seasons. The Reds aren't expected to re-sign Arroyo, who would not cost his signing team a compensatory draft pick. The Twins continue to monitor the market for a handful of other free-agent starters having previously expressed interest in right-handers Phil Hughes and Ricky Nolasco and lefty Jason Vargas. Reports have linked the Twins to right-handers Ervin Santana and Ubaldo Jimenez, as well as lefty Scott Kazmir, among others, as they attempt to bolster the game's worst starting rotation. However, they appear to be furthest along with Arroyo, who reportedly also has drawn interest from the San Francisco Giants. Remaining in the National League would figure to have at least some appeal to Arroyo, who has spent 11 of his 14 seasons there and has averaged $12 million in annual salary over the past five years.
