BA:LTIMORE—Widely hailed as his franchise's best prospect in years, catcher Matt Wieters fulfilled all expectations last Friday with his first major-league at bat, leading the Baltimore Orioles to their first World Series championship since 1983. "It's an incredible feeling—I'm happy I've lived up to everyone's expectations," said Wieters, who has also retroactively led the Orioles to three division titles and a pennant in the last five years. "Just to step in there in a May game against the Tigers and come back to the dugout with a World Series trophy, an MVP award, and three Gold Gloves? I haven't felt this good since I was voted to the All-Star Game as a sophomore in high school." Wieters became the first rookie to win back-to-back world championships in his second at bat before grounding out in the fifth.
