The Nationals promoted Anthony Rendon to Class AAA Syracuse late last night and plan to give their top prospect an extended look at second base, the likely final step toward his permanent arrival in the big leagues.

Rendon had appeared in five games at second base for Class AA Harrisburg but still spent the majority of his time at his natural third base position. In Syracuse, though, he'll work extensively with manager Tony Beasley (a former second baseman himself) on mastering the middle infield, which would prepare him for another promotion to Washington to possibly take over as the Nationals' everyday second baseman, according to sources familiar with the organization's plan.

Having received a paltry offensive performance from their second basemen this season — the group's .539 OPS ranks dead-last in MLB — the Nationals could benefit from adding Rendon's bat to their lineup. The 22-year-old hit .319 with six homers, 24 RBI and a 1.064 OPS at Harrisburg and owns a .952 OPS in 76 total minor-league games over the last two seasons.
