Passan and other Wily Mo-loving fans are promoting the use of #wilymo4derby on Twitter to drum up support for the slugger.
This year's All-Star Game is being held in Pena's home stadium in Phoenix, and the slugger has been putting on a show since being called up from Triple-A in late June. He already has five home runs in only 39 at-bats.
Fielder might not need too much convincing after Wily Mo's performance on Monday. With his Brewers hosting the Diamondbacks, Fielder had a front-row seat to see Pena launch a pinch-hit home run in the fifth inning.
Red Sox fans will remember Pena from his short stint in Boston after the Sox traded pitcher Bronson Arroyo to the Cincinnati Reds in 2006.
