Update: All the latest All-Star additions

Four players in each league have been added to Midsummer Classic rosters

Update: All the latest All-Star additions

This year's All-Star selections were revealed last week, but as Tuesday's game draws nearer, the rosters have been in a state of flux.

Eight players have been added to the National and American League rosters over the past few days, replacing players who will be inactive due to injury or, in the case of two starting pitchers, chose not to take the mound Tuesday on just one day of rest.

In the event a player cannot or chooses not to participate in Tuesday's 86th All-Star Game presented by T-Mobile, it falls to the manager -- in this case, Ned Yost for the AL and Bruce Bochy for the NL -- to select an alternate for the vacant roster spot. If the player was elected a starter via the fan vote, the spot in the starting lineup then goes to whomever among the reserves received the next highest vote totals.

Here's a breakdown of the new additions so far:

American League:

• Angels left-hander Hector Santiago: Replaced A's right-hander Sonny Gray, who started Sunday afternoon and chose not to participate in the Midsummer Classic as he'd be pitching on just one day of rest.

• Twins second baseman Brian Dozier: Replaced Blue Jays outfielder Jose Bautista, who will receive treatment on his sore right shoulder over the All-Star break.

• Yankees outfielder Brett Gardner: Replaced Royals outfielder Alex Gordon, who is sidelined with a Grade 2-plus left groin strain and isn't likely to take the field again until September. Adam Jones will assume Gordon's spot in the starting lineup

• Yankees first baseman Mark Teixeira: Replaced Tigers first baseman Miguel Cabrera, who is on the disabled list with a calf injury. Albert Pujols will start in place of Cabrera.

National League:

• Brewers outfielder Ryan Braun: Replaced Matt Holliday, who's on the 15-day disabled list with left wrist discomfort and isn't due to return until sometime after the break. Dodgers rookie Joc Pederson will replace Holliday in the starting lineup.

• Dodgers left-hander Clayton Kershaw: Replaced Nationals right-hander Max Scherzer, who started Sunday afternoon and chose to be inactive for the All-Star Game rather than pitch on one day of rest.

• Rockies shortstop Troy Tulowitzki: Replaced Marlins second baseman Dee Gordon, who will miss the game after dislocating his left thumb Saturday. Tulowitzki's teammate DJ LeMahieu is slated to replace Gordon in the starting lineup.

• Cubs third baseman Kris Bryant: Replaced Marlins outfielder Giancarlo Stanton, who's recovering from June left hand surgery. Andrew McCutchen will take Stanton's starting spot.
