The specific injury to the rookie is a torn ulnar collateral ligament in his left thumb. The incident occurred on Saturday when he slid head-first into second base in the fourth inning of a game against the Mets. He would stay in the game, but re-aggravated the thumb when he dove for a ball from the shortstop position.
The 23-year-old is hitting .272 with 27 home runs and 72 RBIs, to go along with 21 doubles and 67 runs scored. He set the record for home runs by an NL rookie shortstop, and was closing in on the overall record of 30 set by Nomar Garciaparra of the Boston Red Sox.
The Los Angeles Dodgers also lost a young star, as they optioned struggling outfielder, Yasiel Puig, to the minors on Monday. This move comes one day after the team reportedly informed Puig that he would be either traded or demoted. The outfielder left Dodger Stadium after this conversation and did not travel with the team to Colorado.
The 25-year-old was sent down to make room for recently-acquired Josh Reddick, who will take over in right field on Tuesday night. The team stated that discipline was not a reason for the demotion, although, it is an area for improvement.
The numbers are down for the troubled player, as he is batting just .260 with eight home runs and 34 RBIs in 81 games this season. The Cuban outfielder made his major league debut with Los Angeles in 2013, making an immediate impact, but has been on the decline due to his immature actions on and off the field.
