Hisashi Iwakuma has also been frequently mentioned, given his strong first half. Iwakuma is 7-3 with a 2.42 ERA in 17 starts. He leads the AL in ERA as well as WHIP (0.88) and is fifth in opponent's batting average at .203.
"He's a deserving candidate, no doubt about it," Wedge said. "I think the way he and Felix have both pitched, they're deserving candidates and I think you have to throw Oliver Perez in there as well, just from a pitching standpoint. You just never know how that all plays out. But they're all candidates."
Perez has had a breakout year as a setup reliever, going 2-2 with a 1.47 ERA in 33 appearances with 14 walks and 43 strikeouts in 30 2/3 innings.
The Mariners haven't had a position player in the All-Star Game since 2010, the last of Ichiro Suzuki's 10 consecutive appearances in the Midsummer Classic. Seattle sent three pitchers in 2011 -- Felix Hernandez, Michael Pineda and Brandon League -- and Hernandez was the team's lone representative last season.
