10. Kyle Seager
Seager could be ranked higher, but he's only 25 years old. But, with a .275/.344/.468 line, it's nearly impossible to keep Seager off this list. He provides pop and contact for the Mariners lineup.
9. Michael Young
Michael Young is a very experienced third baseman, which is why he's at number 9. While only hitting a .287/.378/.376 line, he's still has career numbers of .301/.348/.443, which shows that he plays the game and gets on base. Even though he's out of his prime, Young is still a valuable third baseman.
8. Chase Headley
Headley, who spent most of the season on the DL, has finally returned, and has found his stroke. With a .281/.394/.456 line with 4 HR and 14 RBI (32 games), Headley is still an elite 3rd Baseman.
7. Josh Donaldson
Donaldson has burst onto the scene just this season. He only had 89 MLB games prior to the beginning of this season. But, nonetheless, the 27 year old is playing well. With a .308/.383/.517 line, it's almost impossible not noticing him.
6. Pablo Sandoval
The Big Panda is at it again. As the anchor in the Giants lineup, Sandoval has come through. Hitting a .306/.343/.475 line with 8 HR and 34 RBI, Sandoval is playing 3rd as good as anyone else.
5. Adrian Beltre
Ah, look at 'ole Beltre (34 Years Old). But, you can't argue that he hasn't been productive. Hitting a .281/.328/.503 line, Beltre has provided the pop and contact the Rangers need in their lineup. Good job, grandpa!
4. Manny Machado
The only reason Machado's ranked this low is due to experience. Everyone above him has established themselves as a star, by continuing to play at a high level. He has a .330/.362/.527 line with 5 HR and 28 RBI. He has been outstanding. But, the inexperience keeps him to the 4 spot.
3. David Wright
Wright was the star in the WBC and has not let down this season. Hitting .293/.395/.490, Wright is off to a good start. But, he also has 10 SB in 44 games, where he had 15 in 156 last year. His career numbers really rank him this high, though (.300/.382/.505, 210 HR, 846 RBI).
2. Evan Longoria
While Longoria's season may not look as good as Manny Machado's, he has the experience to back him up. This is only his sixth year in the league, but Longoria is an established star already with a career three stat line of .280/.363/.521. He's the anchor in the Rays lineup.
1. Miguel Cabrera
Cabrera is a very good hitter, no doubt. He's also good with the glove. With a 3 stat line of .391/.467/.701, Cabrera is making is 2012 Triple Crown season look like a joke so far. And, that's saying something. Cabrera is obviously the best third baseman in the league.
