SEATTLE (AP) — The Seattle Mariners have acquired perhaps the top starting pitcher on the trade market, getting All-Star Luis Castillo from the payroll-paring Cincinnati Reds for four minor league prospects. Cincinnati obtained infielders Noelvi Marte and Edwin Arroyo, and right-handers Levi Stoudt and Andrew Moore. Marte was the Mariners’ top-rated prospect, Arroyo was third and Stoudt fifth. Seattle has not been to the playoffs since 2001, the longest postseason drought in the four major North American pro sports.
