Those are just two of the most prominent Orioles on the ballot, a group rounded out by first baseman Aubrey Huff, shortstop Cesar Izturis, third baseman Melvin Mora and outfielders Adam Jones and Luke Scott. Catcher Gregg Zaun also made the cut for the ballot.
The most intriguing names, however, remain Roberts and Markakis. Roberts, a two-time All-Star, flirted with hitting .400 for the first two weeks of the season. And Markakis, who led the Major Leagues in outfield assists (17) last season, has had an atypically strong start but remains hemmed in by a deep crop of outfielders.
"It's a great process, and I think it's good for fans," Roberts said. "Do all the right guys always make it? No, but that's part of it. There's always going to be something controversial, but it's fun for the fans and good for the game."

Baltimore's All-Star last season was closer George Sherrill, who was selected by Boston and American League manager Terry Francona. The Orioles haven't had more than one All-Star since 2004, and they had four -- Roberts, shortstop Miguel Tejada, third baseman Mora and closer B.J. Ryan -- that year.
The Orioles have seen Jones take a great leap forward in his second full season, and he'll be a name that might be intriguing to fans in other cities. That also may be the case for Huff, who won the Silver Slugger last year as a DH and has since moved to first base. Mora, a two-time All-Star, also may have national appeal.
