The Philadelphia Phillies pointed bats at him like guns.
The Philadelphia Phillies dugout pointed their bats like guns at Robinson to mock him for the death threats he was receiving. In fact, Branch Rickey (the man who signed Robinson) credited Phillies Manager Ben Chapman with uniting their team around Robinson by heckling Jackie relentlessly throughout an early April contest during his rookie season.
The heckling was so outrageous that baseball's commissioner Happy Chandler actually threatened Chapman with disciplinary action if he couldn't control himself. Eventually the Phillies finished 62-92 that season tied for dead last with the Pirates, a whopping 32 games behind the Dodgers who won the pennant en route to the World Series. Chapman was fired halfway into the next season when his team was again in last place.
