Ervin Santana, Bartolo Colon and Darren Oliver have all had rough first halves to the 2007 season. Ervin Santana is 5-10 this season with a 1.54 WHIP so far this season. In 104 innings this year Santana has allowed 122 hits and 23 homers! That will need to change soon or Santana will be replaced in the starting rotation. Bartolo Colon has also had a rough first half of the 2007 season. He is now 6-4 with a 6.44 ERA and a 1.62 WHIP so far this season. He has allowed 107 hits and 15 homers in only 79.2 innings this season and that can’t be tolerated much longer. Darren Oliver is the only lefty in the bullpen for the Angels and he is 0-0 with a 5.79 ERA and a 1.71 WHIP. The Angels have been using him as a mop up man and that’s all he will likely be as he can’t be trusted in pressure situations.
