Tim Lincecum = Very, very good.
Wait, I already did that as my opening for Roy Halladay? darn. Well, this 25-year old superstar is freakishly good, and is throwing even better than Halladay this year. He already has two Cy Young Awards, and may be adding another one to his mantle this year if he keeps it up. Keep in mind this is only his 4th big league season.
He has a one-of-a kind delivery, in which he delivers straight over the top. He has an extremely long stride (even longer than Johan's), and he features three plus pitches. Even though he's lost 3 mph on his fastball since first taking the league by storm, he is now featuring a two-seamer 15% of the time (which has resulted in an increase in his ground ball rate to 50%) and he is averaging his fastball velocity around 91 (but his "rising" four-seam fastball still hits 94-95). He also throws a plus curve, and a plus-plus change, that probably is the best in baseball. He throws his change-up for a strike 75% of the time (league average is 60%. Hat Tip to Fangraphs). The craziest stat is that he gets a 34% swing and miss rate on his change-up (league average is 12%). He gets a ton of swing and misses outside of the strike zone, which helps to maintain his K/9 > 10, and his walk /9 < 3.
This year he has a 4-0 record with a 1.73 ERA and a minuscule 0.83 WHIP. He's gone 7+ innings in five of his six starts, and has eight walks to his 56 strikeouts (42 1/3 innings). He's struck out 10+ batters in three starts so far this year.
He is one of the top three pitchers in baseball, and will be very difficult to beat (if you couldn't figure that out from all those numbers above).
