The Pirates are interested in outfielder Yoenis Cespedes and free agent left-handers Wei-Yin Chen and Tsuyoshi Wada, according to Rob Biertempfel of the Pittsburgh Tribune-Review (Twitter links). However, they'll quickly back away if the bidding on Cespedes gets "crazy." Cespedes is expected to become a free agent relatively soon and Wada and Chen have been able to negotiate with MLB teams since free agency began Thursday.
Wada posted a 1.51 ERA with 8.2 K/9 and 1.9 BB/9 in 184 2/3 innings for the Fukuoka Softbank Hawks in 2011. The 30-year-old is a Dallas Braden type with "a 86-87 mph fastball, a good circle change, and a solid slider," according to Patrick Newman of FanGraphs.
MLBTR's Tim Dierkes suggested last month that a four-year, $20MM deal might be enough to sign Chen. The 26-year-old posted a 2.68 ERA with 5.1 K/9 in 164 2/3 innings this past season.
