Weaver will start in Seattle on Opening Day, MLB.com's Alden Gonzalez reports. Weaver will be followed, in order, by C.J. Wilson, Matt Shoemaker and Hector Santiago. With the Angels expected to use a four-man rotation the first time through, Weaver's second start lines up for Saturday in Anaheim against the Royals. Owners will want to keep a close eye on Weaver's velocity, as the right-hander's fastball has only been around 82-84 mph recently.
