AL Notes: Angels, Orioles, Mariners, Yost

In a long article outlining the Angels' troubles under Arte Moreno, CBS Sports' Scott Miller reports that the Halos owner was the driving force behind the club's ill-fated trade for Vernon Wells before the 2011 season. Moreno threatened to fire former GM Tony Reagins if he failed to complete the deal within 24 hours, Miller says.  Here's more out of the American League..

• The Orioles continue to scour the waiver wire in hopes of acquiring another bat, Roch Kubatko of MASNsports.com tweets. The club believes a deal is possible ahead of Aug. 31, but nothing's cooking at the present, Kubatko says.
• Mariners GM Jack Zduriencik's job seems to be more secure as the club begins a "management shakeup," Yahoo! Sports' Jeff Passan tweets. Special assistant Tony Blengino has been fired, according to Passan.
• Meanwhile, the club continues to remain silent on Zduriencik's future, FOX Sports' Jon Paul Morosi says. Neither President Chuck Armstrong or chairman Howard Lincoln have publicly stated that Zduriencik will return next season. 
• Bill Madden of the New York Daily News runs through lame duck managers around the majors, calling the Yankees' Joe Girardi a manager of the year candidate and urging the Mets to bring back Terry Collins.  However, Ned Yost of the Royals and Eric Wedge of the Mariners are in line to be let go, while the Tigers' Jim Leyland should be on the hot seat, Madden says.
• Erik Bedard confesses he was surprised after being informed he will shift into a relief role for the Astros, a move manager Bo Porter says will allow the club to get a look at a young pitcher. "They said they looked at my last two years and my innings total was around where I'm at right now, and they said if I keep pitching I'll be about 40 over, and I said, 'Yeah, that's the point,' Bedard is quoted as saying in an article by Brian McTaggart of MLB.com. Bedard, who signed a one-year, $1.15MM minor league deal with the Astros in the offseason, cleared waivers earlier ths month and is eligible to be traded.
• Orioles pitching prospect Kevin Gausman could join the major league club prior to roster expansion in September, and would likely slot into the bullpen, Brittany Ghiroli of MLB.com says. Gausman was ranked the No. 26 prospect in baseball after the 2012 season by Baseball America, but posted an unsightly 6.21 ERA in 33 1/3 innings after being called up earlier this season.
