The Pirates on Monday announced their plan to add minor league outfielder Andrew Lambo to the active roster Tuesday, bringing one of the Pirates' best minor league hitters this season to a team in need of offensive help.
The left-handed Lambo, who turned 25 Sunday, has a .350 on-base percentage and 31 home runs this season between Class AA Altoona and Class AAA Indianapolis.
The Pirates will make corresponding moves to add Lambo to the active and 40-man rosters when he arrives in St. Louis with the team. The move could mean Starling Marte will go on the disabled list because of a hand injury previously thought not to be too serious. The Pirates could also option Alex Presley to Indianapolis.
The Pirates' 40-man roster currently has an open spot, so the Pirates don't need to clear a spot. They could also put Wandy Rodriguez or Michael McKenry on the 60-day disabled list if they choose.
Lambo joined the Pirates from the Los Angeles Dodgers with James McDonald in exchange for Octavio Dotel at the 2010 trade deadline.
Lambo's season comes after several up-and-down years in the minor leagues. He hit for average and power in 2007 and '08, his first two seasons in professional baseball after being drafted in the fourth round of the 2007 draft. He plateaued in Class AA in 2009 and '10.
He reached Class AAA in 2011, but hit .184 in 60 games there. Injuries limited him to 35 games in 2012.
He started this season in Altoona and hit .291 with 14 home runs. After 58 games, he was promoted to Indianapolis, where he hit .278 with 17 home runs in 59 games.
The Pirates' offense could use the help. They just scored seven runs during a three-game sweep against the Colorado Rockies at offense-friendly Coors Field.
Lambo has never appeared in the major leagues.
