DENVER (AP) -- Prized prospect Drew Pomeranz threw five shutout innings in his major league debut and Ty Wigginton homered, helping the Colorado Rockies to a 4-1 win over the Cincinnati Reds on Sunday.
Pomeranz (1-0) was a key piece in the deal that sent ace Ubaldo Jimenez to Cleveland at the trade deadline. He showed why the Rockies coveted him, allowing just two singles.
The 21-year-old lefty threw only 63 pitches before leaving in the fifth. Pomeranz is three weeks removed from an emergency appendectomy.
Edinson Volquez (5-5) was effective in his first start since July 5, not allowing a hit until Wigginton's homer to left in the fourth. He later gave up an RBI single to Jordan Pacheco.
