PITTSBURGH -- Gregory Polanco is headed to the majors. The Pittsburgh Pirates called up their coveted outfield prospect late Monday night after placing second baseman Neil Walker on the 15-day disabled list. Walker experienced abdominal pain shortly before Pittsburghs 6-2 win over the Chicago Cubs and underwent an emergency appendectomy. Pirates fans have been waiting eagerly for Polanco to arrive. The 22-year-old from the Dominican Republic was hitting .347 with seven home runs in 62 games for Triple-A Indianapolis. Polancos arrival will likely move utility player Josh Harrison to second base. Harrison has sparkled in right field since being given the job on a full-time basis last month. Harrison played second on Monday night after Walker was scratched.
