Could revolving door at Angels' first base be Auditions for trade market?

Back in May, a bright Saturday Afternoon, in Anaheim.  Those were simpler times.  In the process of a comeback and the bases were loaded.  Angels First Baseman Kendry Morales stepped into the batters box, all the while being televised on Fox for a National Game. Morales launched a walk-off grand slam and won the game.  But not all would be golden for the Halos, his first career grand slam, would later become his final plate appearance for the 2010 season.  While coming to home plate after his monstrous swing, joining the bench clearing celebration, poor Kendry would break his leg jumping on to home plate.

All the talk was who would replace Kendry at 1st?  Obviously it would be difficult to find someone who could match the power and defense that Kendry provided.  Brandon Wood attempts were futile. Kevin Frandsen was a decent fit, but provided little power.  And a bevy of Minor Leagues would attempt to replace Morales, Paul McAnulty, Michael Ryan, and Robb Quinlan.  There was even at least one attempt to make a trade for the Chicago Cubs' 1st Baseman Derrek Lee, that didn't happen because of Lee's no trade clause. Lately there has been fills ins like Howie Kendrick, Bobby Wilson, and probably receiving the most starts at 1st, Mike Napoli.  But for the past few nights, following Napoli being claimed on the wavier wire the tenth man in an Angel uniform suited up for 1st base.  Juan Rivera.

Although Mike Napoli wasn't claimed on Waivers and a trade involving Napoli will not be made, Rivera has been doing a phenomenal job at first base.  But I believe this has more to do with an attempt to move Rivera and not Napoli.  Tony Reagins mentioned in passing that nearly half the Angels were placed on Waivers.  Only 4 names were discovered by the media.  Brian Fuentes- who was later traded to the Twins, Mike Napoli- who was claimed by Boston (know deal was made), Bobby Abreu and Juan Rivera.  Since there has been no reports of Rivera being claimed off of waivers, I have to believe he has cleared waivers.

Could Rivera's strong performance at 1st Baseman make him an asset to a contending team?  Or an upgrade to a non-contending team who is in need of a corner outfielder and 1st baseman be desirable to work out a trade.  Rivera's contract his affordable.  Is this an audition for Rivera?  Only Tony Reagins and Mike Scioscia know for sure.  

Go Halos
