The curiosity factor, at least on the public scale, had plummeted by Thursday afternoon after reaching an all-time high only 24 hours earlier. Neftali Feliz's first start of the spring couldn't come close to the level of hype generated for Yu Darvish on Wednesday. But the closer-to-starter move Feliz is making is just as important to the Texas Rangers this season as Darvish's transition from Japan to the major leagues. And there might be more questions about Feliz, starting with how many innings will he be able to handle and how effective can his off-speed pitches be.
