An on-and-off rivalry with the Pittsburgh Pirates stems from the close proximity of the two cities, and features some carryover elements from the longstanding rivalry in the National Football League between the Cleveland Browns and Pittsburgh Steelers. Because the Indians' designated interleague rival is the Reds and the Pirates' designated rival is the Tigers, the teams have played periodically, with one three-game series per season from 1997 to 2001, 2003, 2006, 2009–12, 2015, and 2018. Since 2012, the Indians and Pirates play three or four games every three seasons when the AL Central plays the NL Central as part of the interleague play rotation. The Pirates lead the series 21–18. The teams will play six games in 2020 as MLB instituted an abbreviated schedule focusing on regional match-ups
