A relentless Anthony Rizzo teased Dioner Navarro as only an ex-teammate could

Catcher Dioner Navarro is a member of the White Sox. Back in 2013, Navarro was a member of the Cubs, appearing in 93 games. Anthony Rizzo's tenure with the Cubs began in 2012. Therefore, the two of them were teammates in 2013. (Thanks, math class!).

Rizzo strode to the plate in the fifth inning, prepared to assume his place in the batter's box to face Chris Sale. Too bad Navarro was in the way. No matter, a lighthearted shove ought to do the trick:
