10:36am: Bross has received calls from 15 teams regarding Arroyo but hasn't received a formal offer at this time, according to the Boston Globe's Nick Cafardo (Twitter link).
10:31am: The Twins will also meet with Bross to discuss Arroyo today, according to Darren Wolfson of 1500 ESPN (on Twitter).
The Pirates have some uncertainty in their rotation given A.J. Burnett's pending decision on retirement or returning to baseball. Arroyo would fill the need of a veteran starter for the Bucs, though he'd likely command a sizable two-year deal at the least, which could prevent the Pirates from becoming too interested, given their tight budget.
Arroyo, who will be 37 in February, posted a 3.79 ERA with 5.5 K/9, 1.5 BB/9 and a 44.4 percent ground-ball rate in 202 innings this past season. With the exception of a 199-inning campaign in 2011, Arroyo has pitched at least 200 innings each season dating back to 2005. An Arroyo signing would be a departure from the low-cost, high-upside moves the Pirates have made to bolster their rotations in recent years, such as acquiring Burnett from the Yankees (with New York footing most of the bill) and signing Francisco Liriano to a low-cost two-year deal.
