With the trade deadline now five days away, some executives spent part of Wednesday digesting the deals that took place late Tuesday night and continuing their assessments of their own teams and the market.

The number of shopping days is dwindling, and here are the biggest holes to be filled:

1. Los Angeles Angels: Starting pitcher
There is so much for the Angels to love about their team. Some rival GMs already are saying Mike Trout is the best player in baseball, and he's at the top of what is a really good lineup. Angels ace Jered Weaver has been throwing well, and Dan Haren looked OK in his return to the rotation on Sunday night. Ernesto Frieri might turn out to be the best pickup made by any team all season; since GM Jerry DiPoto made his deal for the right-hander, Frieri has 69 strikeouts in 41 innings with a 1.54 ERA.

But the Angels don't have a big margin for error in the AL West, given the presence of the Texas Rangers and the blistering hot Oakland Athletics, and they do have a real weakness at the back end of their rotation. Ervin Santana has an ERA of 6.00 and has been placed on a 15-out plan by manager Mike Scioscia in an effort to get him right, and Jerome Williams tends to be very Jekyll or Hyde.
