Polar Park, in Worcester, MA, is the home of the Worcester Red Sox, the Boston Red Sox' Triple-A East farm team, and the Red Sox' 2021 Coronavirus pandemic alternate training site. At $157 million, it displaced two-year-old Las Vegas Ballpark as the minors' most expensive playpen. Local seltzer distributor Polar Beverage owns naming rights and its chief executive officer joined the WooSox ownership group.
When the Pawtucket Red Sox were sold after owner long-time Ben Mondor died, McCoy Stadium was nearly 75 years old. The new owners tried to get first Providence, RI, and then Pawtucket to build a new ballpark. When neither happened, Worcester invited the club to New England's second-largest city via a postcard campaign. The July 2019 groundbreaking aimed for a 2021 opening, and the pandemic only briefly halted construction.
Polar Park opened, limited by pandemic restrictions, to 2,377; 6,442 attended its first no-limit date; two rehabbing BoSox players drew the house baseball record, 9,508, as pitcher Chris Sale started and won while second baseman Marwin Gonzalez homered.
Playing on an inside-baseball joke, Polar's foul poles are each labeled "FAIR POLE" - the joke being that, because a batted ball that hits a foul line (or pole) is fair, they should be called the fair lines.
