Superstars Vladimir Guerrero Jr., Fernando Tatis Jr. and Shohei Ohtani are still shining in the 2021 MLB All-Star Game voting.

Guerrero, Tatis and Ohtani have big leads for the starting All-Star spots at their positions at the first standings update for Phase 2 of the balloting, which was released Tuesday. But there are lots of close races -- and more than one shakeup in the standings among the finalists.

Check out the American League second-base race. In the closest race at any position, Marcus Semien is leading Jose Altuve by a single percentage point in the voting. Or the AL outfield race, where the second- through sixth-place vote-getters -- Aaron Judge, Byron Buxton, Michael Brantley, Cedric Mullins and Adolis García -- are separated by a total of just 4 percentage points.

Or how about the National League third-base race? Nolan Arenado is leading second-place Justin Turner by only 3 percentage points … and Turner is only ahead of third-place Kris Bryant by another three points. Or the NL outfield race, where third-place Jesse Winker and fourth-place Mookie Betts are also only 3 percentage points apart.

We also have some new leaders at several positions. Arenado has taken over first place for the starting NL third-base spot from Bryant, who led at the end of Phase 1 voting. At NL first base, Freddie Freeman has taken over first place from Max Muncy. And at NL second base, Adam Frazier has overtaken Ozzie Albies.

Fans can vote for the All-Star Game at mlb.com/vote -- or on Google by searching "MLB All-Star vote" or "Vote" along with a player's name. You can vote daily on both platforms, including once per day on MLB.com. Voting ends on Thursday at 2 p.m. ET.

If voting ended today, the Blue Jays (Guerrero and Semien), Red Sox (Rafael Devers and Xander Bogaerts), Reds (Nick Castellanos and Jesse Winker) and Braves (Freeman and Ronald Acuña Jr.) are the only teams who would have multiple All-Star starters. But that could all change.

Here are the standings at each position for the American League and National League, with each player's percent of the All-Star vote.
