Who is the most valuable fantasy player going? Are saves "worth" more or less than stolen bases? How do you compare a hitter to a pitcher on an equal playing field? We at Rototimes.com have a tool called the Player Rater, and each week I will discuss the top-50 fantasy baseball players based upon the rankings provided by this tool using the following parameters: a 12-team mixed league using standard 5x5 scoring with 14 hitters, nine pitchers and a $260 salary cap.

1. Lance Berkman, 1B/OF, HOU: Over his last 12 games he has hit .211 without a single home run, though his overall production is still staggering (.347-22-73-79-15).

2. Ian Kinsler, 2B, TEX: If he didn't play another game this year this would already be the best season of his young career (.337-14-58-84-23).

3. Hanley Ramirez, SS, FLA: Amazingly he just keeps getting better. His steals might be down a bit (23), but the power (23 home runs) is growing.

4. Josh Hamilton, OF, TEX: The amazing story appears to have no end in site for Hamilton, who leads baseball with 95 RBIs, putting him on pace to push 160 RBIs.

5. Jose Reyes, SS, NYM: Since the calendar flipped to May, Reyes has been hitting the ball hard leading to a .321 average in 290 AB.

6. Chase Utley, 2B, PHI: Still in a bit of a funk at the plate hitting just .255 with only two home runs over his last 51 AB.

7. Chipper Jones, 3B, ATL: Over his last 31 games Chipper is batting .304, just slightly below his .310 career mark but well below his .376 season long average.

11. Alex Rodriguez, 3B, NYY: This is one Yankee that loves hitting at home (.355-12-32 with a 1.123 OPS).

12. Cliff Lee, SP, CLE: You simply can't call it a fluke anymore as every time you are about to write him off he rebounds like the All-Star he is (1.86 ERA, 0.90 WHIP over his last four starts).

14. Mariano Rivera, RP, NYY: With a 0.64 WHIP, 11.84 K/9 and an amazing 12.5 K/BB ratio, has this been the best half season of the Hall of Famers career?

38. Kerry Wood, RP, CHC: A blister will keep him out of the All-Star game, but it hasn't stopped him from racking up 24 saves with a 4.23 K/BB ratio.
