The NL Rookie of the Year race has changed little since we checked in one-third of the way through the season. Randy Wells and J.A. Happ were neck-and-neck then, and I gave the nod to Wells, even though I expected more from Happ the rest of the way.

At least a few hitters have started to play catchup now. As of June 5, the league had just three position players with a VORP of 5.0 or better: Joe Thurston (7.3), Ryan Roberts (7.3) and Ryan Hanigan (5.1). Now we have four over 10.0:

1. Casey McGehee - 16.3
2. Colby Rasmus - 14.0
3. Ryan Hanigan - 12.6
4. Andrew McCutchen - 10.3

Seth Smith is at 15.2, but he spent too much time on Colorado's bench last year to qualify as a rookie.

Factoring in defense, Rasmus rates as the NL's top rookie to date. He's hitting .278/.329/.478 in 270 at-bats and seemingly getting better every week. McGehee has hit a surprising .329/.387/.541 in 146 at-bats.

The pitching crop remains much stronger, of course. Again going by VORP:

1. J.A. Happ - 25.8
2. Randy Wells - 23.5
3. Ramon Troncoso - 19.7
4. Ronald Belisario - 14.5
5. Mark DiFelice - 14.0
6. Tommy Hanson - 11.8
7. Alberto Arias - 10.6
8. Evan Meek - 10.3
9. Burke Badenhop - 10.1
10. Luke Gregerson - 9.5

Wells has a slight ERA advantage over Happ (2.72 to 2.90), but Happ has pitched 11 more innings and faced the more difficult schedule. The left-hander is the choice this time, and while both should see their ERAs rise over the rest of the year, I expect Happ to retain more of his value going forward.

Third place is between Troncoso and Rasmus. Troncoso not only has the 1.75 ERA in 56 2/3 innings, but he's been especially good in high-leverage situations. He's picked up five saves and eight holds, yet he's been charged with just one blown save to date. I'll choose him over Rasmus for now, though Rasmus will almost certainly rank ahead of him by season's end. My guess is that it will materialize into a three-man race between Happ, Rasmus and Hanson.

Midseason NL ROY
1. Happ
2. Wells
3. Troncoso
