Who Should be the National League Pitcher of the Month for April?

I can never remember a season in which so many pitchers have started off the season so well and that will mean a hotly contested NL Pitcher of the Month Award for April. The candidates:

Roy Halladay: 4-1, 1.80 ERA, 40 innings, 36 hits, 3 BB, 33 Ks, 1.6 WAR
Special Consideration Stat: 2 CG and 1 SHO

Mike Pelfrey: 4-0, 0.69 ERA, 25 innings, 18 hits, 13 BB, 19 Ks, 0.7 WAR
Special Consideration Stat: 1 Save

Ubaldo Jimenez: 5-0, 0.79 ERA, 34 1/3 innings, 22 hits, 14 BB, 31 Ks, 1.3 WAR
Special Consideration Stat: No-hitter

Tim Lincecum: 4-0, 1.27 ERA, 35 1/3 innings, 22 hits, 7 BB, 43 Ks, 1.5 WAR
Special Consideration Stat: 2.01 Fielding-Independent Pitching, lower than the other three guys




I'm voting for You-Baldo because he's giving up fewer runs and a no-hitter is pretty special. But Lincecum should probably be the choice of the sabremetricians considering he'd be 5-0, with a lower ERA if his bullpen hadn't blown it.
