A funny thing happened to Tim Crabtree last season, his seventh in professional baseball. He learned how to pitch. Crabtree, the Rangers' 29-year-old righthanded setup man, has no trouble explaining why: He had a good teacher. After spending six years in the Blue Jays' organization, Crabtree came to Texas in a spring training deal last year and began to study every move closer John Wetteland made. "Just being around Wetteland made me a smarter and tougher pitcher," says Crabtree, who had a 1.20 ERA in his final 10 appearances. "I learned that it's just mi and the hitter, one-on-one. Nothing tricky. Like John I throw hard, and I learned to challenge hitters."
