TRENTON -- Jameson Taillon, ranked by MLB.com as the top prospect in the Pirates' organization and fifth-best in all of baseball, made his first Double-A appearance Tuesday for Pittsburgh's Altoona Curve against the Trenton Thunder.
Taillon worked five scoreless innings and struck out six. He scattered four hits and walked none while throwing 46 strikes in 67 pitches.
The 6-foo-6 righty was promoted to the Curve on Friday from Class A Bradenton. He was the No. 2 overall pick in the 2010 First-Year Player Draft and spent the 2011 season with the Class A West Virginia Power, where he threw 92 2/3 innings as a 19-year-old in his first professional campaign.
With his Tuesday outing, Taillon has now surpassed that mark by 37 innings this season. He was 6-8 in 23 starts for Bradenton with two complete games. The Florida native struck out 98 in 125 innings while walking just 37, and held opponents to a .230 batting average prior to his promotion.
