Chan Ho Park, RHP, Rangers
A major disappointment since he signed a $65 million deal with Texas in 2001, Park had one of his best outings for the team last Friday, pitching seven innings in a 5-0 win over the Mariners.
After finishing last in the NL in hitting (.243) and runs (3.5 a game) last season, L.A. was on top of the NL West and ranked third in the league in batting (.288) at week's end, thanks mostly to catcher Paul Lo Duca (.512) and third baseman Adrian Beltre (.362).
Jose Mesa, RHP, Pirates
Run out of Philadelphia last year after putting up a 10.50 ERA in the second half, he's been dominant in converting five of five save opportunities.
The starters were the reason for Kansas City's 11-1 improbable start last season, but at week's end they were winless in their first 12 games and had a 7.84 ERA.
Rich Harden, RHP, A's
Since winning three of his first four starts after being called up last July, he had lost five of his last seven decisions. In his 2004 debut last Thursday, Harden gave up six runs and II hits in four innings.
Five times in its first eight games Seattle was either leading or tied through six and a half innings, only to have its bullpen blow the game.
