Liddi, 21, and Peguero, 23, both play for Double-A West Tennessee, where they've been driving forces for the Diamond Jaxx's offense. Peguero is 12th in the Southern League with a .301 batting average and second with 15 home runs. Liddi ranks third in the league in RBIs (51) and triples (five) while hitting .290.
Both players will represent the World Futures team and compete against the US squad. The two 25-man rosters were chosen by MLB along with the MLB Scouting Bureau, MLB.com, Baseball America and the 30 clubs.
The 12th annual Futures Game can be seen live on MLB.TV, ESPN2 and ESPN2 HD and followed live on MLB.com's Gameday. In addition, XM Radio will broadcast play-by-play coverage of the event live on XM 175. MLB.com will also provide complete coverage before, during and after the game.
Liddi is the only Italian player in the Futures Game, while Peguero is one of 12 on the World squad from the Dominican Republic.
Liddi played in the game last year along with former Mariners prospect Tyson Gillies (now in the Phillies' organization), and each scored a run in the World Futures' 7-5 win. Liddi was the California League Most Valuable Player in 2009, and he's hit .375 with runners in scoring position this season.
"I got a chance to see both of them this spring in limited time," said Mariners manager Don Wakamatsu. "Peguero is a guy who has as much power as anybody in our system for sure. He has a chance to be an impact bat at the Major League level. His numbers are good down there. Strikeouts are a little high, but the power is there.
"I was real pleased with [Liddi's] defense [in Spring Training]. He's another guy that's got some leverage in his swing. He's just a younger player that needs to develop, but he has a high ceiling."
High ceilings are what the Futures Game is all about. Sixty-two participants have gone on to be MLB All-Stars, including a record 30 in 2009 alone, eclipsing the mark of 23 in '08.
There are 201 players from the XM All-Star Futures Games on Major League active rosters or disabled lists.
