For comparison, the NBA on June 26 reported a 5.3% rate of positive tests (16 of 302) among players, while MLS announced a positive rate of 2.7% (18 of 668) among players two days later.

The positives come from 19 MLB teams, the league said. All 30 teams began training camp Friday at their home ballparks.
