Manager Buck Showalter said -- as long as the rotation stays on turn -- Hammel's final start before the break will be on July 7, which makes him a viable option for AL manager Ron Washington.
While Hammel's career-high eight earned runs allowed in a season-low 3 1/3 innings during Baltimore's 13-1 loss to the Angels hurt his case, the Orioles' All-Star hopes are still high.
Baltimore -- led by a surprisingly strong pitching staff -- is expected to have multiple representatives at this year's All-Star Game, which will be played on July 10 at Kauffman Stadium in Kansas City.
In addition to Hammel, closer Jim Johnson and starter Wei-Yin Chen have made strong cases, along with outfielder Adam Jones and catcher Matt Wieters, who can be voted in as part of MLB's online voting. The Orioles have not had more than one All-Star since sending four players in 2005, including two starters in Brian Roberts and Miguel Tejada.
"It's pretty fair, I think," Showalter said of how the squads are selected. "The bottom line is the fans are voting in who they want to see, but at the same time, it's not an exhibition, because there's a lot of meaning in what happens in that All-Star Game. It will be for good fodder about who should and who shouldn't [make the team]. I'm very biased about our guys, but I get to see them all the time."
Showalter -- who didn't plan on reaching out to Washington before Sunday's All-Star Game Selection Show on TBS -- managed the AL squad in the 1995 All-Star game and said it was a challenge to make sure no one got injured and to not run out of players while remaining competitive.
"I know how tough a job it is," he said. "It's different than when I did it, it's kind of taken out of the manager's hands mostly, which I'm sure Ron's OK with.
"[Washington is] aware of who's having worthy seasons around. It's more League-oriented."
