Grienke beat out Felix Hernandez (Mariners), Tim Wakefield (Red Sox) and Roy Halladay (Blue Jays).
So far in May, he's picking up where he left off. He's now 6-0 and has lowered his ERA to 0.40 after pitching a complete game shutout last night.
However, he doesn't believe he's the best pitcher in baseball.
“I think Johan (Santana) and Roy Halladay are the two best pitchers,” Greinke said. “Without a doubt. You’ve got to do it for at least three years. That’s my (guideline). When you do it for three years, then you can put your name in stuff like that.”Speaking of Santana, he was named the N.L. pitcher of the month for April.
Santana went 3-1 in April with an ERA of 1.10. He struck out 44 batters in 32 2/3 innings.
He beat out Chad Billingsley (Dodgers), Dan Haren (Diamondbacks), Heath Bell (Padres) and Ryan Franklin (Cardinals).
