Tucupita Marcano: Everything you need to know

Major League Baseball announced Tuesday that Marcano has been issued a lifetime ban for violating the league's gambling policy, Jared Diamond of the Wall Street Journal reports. MLB's investigation found that Marcano bet more than $150,000 on baseball, with $87,319 being in MLB-related wagers. Marcano didn't play in any of the games he bet on, and the league has determined the outcomes of the games in which he placed bets weren't compromised in any way. The 24-year-old had been on the Padres' 10-day injured list while completing a recovery from ACL surgery.

Major League Baseball is currently investigating Marcano (knee) for a violation of the sport's gambling policy, which could result in a lifetime ban, Jared Diamond and Lindsey Adler of The Wall Street Journal Report report. According to the report, four other players are under investigation along with Marcano, a 24-year-old infielder who has been on the Padres' 10-day injured list all season while he completes his recovery from a torn ACL. Per Jeff Passan of ESPN.com, while MLB's investigation isn't yet complete, a penalty for Marcano could be imposed in the coming days. Marcano has seen big-league action in each of the previous three seasons as a member of the Padres and Pirates, slashing .217/.269/.320 with five home runs and seven stolen bases across 447 career plate appearances.

Marcano (knee) has been taking groundballs as he begins to ramp up his baseball activities, per MLB.com. Marcano continues to rehab from the ACL surgery he underwent in August of last year. The 24-year-old was placed on the 10-day IL on March 19, so he'll be eligible to return as soon as he's physically ready to do so. Given that Marcano didn't see any spring training action, he'll likely require an extended rehab assignment in the minors before the Padres consider promoting him to the big-league roster.
