If there is a close American League comparison to what the Giants have in the NL it is found in Motown, where a pair of hard-throwing righties in their mid-20s have carried an otherwise unremarkable ballclub into the heart of the playoff chase. Verlander, 26, has been the Tigers best pitcher since his first full season as a 23-year-old in 2006. He's one of the hardest throwers in baseball, and leads the league in both strikeouts and K/9. Perhaps his most interesting development has been his control. He has drastically reduced his BB/9 (from 3.9 a year ago to 2.5 this season), while more than doubling his K/BB ratio (1.9 to 4.2).
If Verlander, the No. 2 pick in the 2004 draft, was more of a sure thing, than Jackson has been a pleasant surprise. He's been in the majors since his 20th birthday, when, in 2003, he memorably beat Randy Johnson in his major league debut as a September call-up. But despite a world of talent, he spent more time in the minors over the next three years, and was just 5-15 when he finally cracked a big league rotation in 2007. Despite leading the pennant-winning Rays with 14 wins a year ago, he was bumped from their rotation in the postseason, and traded straight up to the Tigers for prospect Matt Joyce. While Joyce has batted .188 in 11 big league games, Jackson has blossomed into an All Star, ranking third in the league in ERA, eighth in WHIP and third in fewest hits per nine innings.

I tend to agree, both on their own are equally impressive...
