I like Ishikawa
Giantsfan9 took this great photo posted at Giants Jottings, noting that Travis Ishikawa nearly homered in Saturday's game with one of the hardest hit balls of the game. I saw Travis break in last year in late May with a 3-for-3 as Felipe finally decided to stop the stupid Jose Vizcaino experiment at first base and give the kid a start. He responded with two long doubles -- not cheapies that dribbed down the lines but booming shots into the gaps that flew off his bat.
All told, he went 7-for-24 last year with 3 doubles and a triple, and he was only 22 at the time. I'd say he was a helluva lot promising even at that young age as a first baseman than the Niekro/Sweeney/Vizcaino/Hillenbrand fiasco.
