When one looks deep into the Mariner farm system, many names jump off the stat page and plant a seed of curiosity. How old is this kid? How long until he makes the big leagues?

Hernandez, 18, is baffling California League hitters as the circuit's youngest pitcher.

2. Jose Lopez, SS/3B, Tacoma Rainiers
.280/.332/.505, 11 HR, 28 RBI, 4 SB
Prior to the recent knee injury, Lopez, 20, was steadily becoming the player the M's thought he would.

3. Adam Jones, SS, Wisconsin Timber Rattlers
.263/.328/.394, 4 HR, 33 RBI, 4 SB
Jones, 18, is more than holding his own as one of Midwest League's youngest hitters.

4. Wladimir Balentien, CF, Wisconsin Timber Rattlers
.257/.299/.466, 7 HR, 25 RBI, 8 SB
Balentien, 19, has rebounded from rough start to become one of the biggest power threats in the league.

Guzman, 19, skipped two levels and is showing great promise at the plate.

6. Cesar Jimenez, LHP, Inland Empire 66ers
2-5, 2.50 ERA, 39.2 IP, 34 K, 6 BB

7. Ivan Blanco, RHP, Aguirre Mariners (VSL/VWL)
7-0, 0.97 ERA, 74.1 IP, 103 K, 15 BB

8. Aaron Jensen, RHP, Everett Aqua Sox (2004)
No Statistics (signed late in 2003)
Jensen, 20, is armed with a plus 12-6 curve and low 90's heat. The Northwest League will be a good challenge for him.

Womack, 20, combines plus speed with solid all-around skills to get solid results in a league tough on young bats.
