Gomez was suspended for five games and fined an undisclosed amount for intentionally throwing at and hitting Moustakas, it was announced on Wednesday by Joe Garagiola Jr., Major League Baseball's senior vice president of standards and on-field operations.
Gomez has appealed and the discipline will be delayed until the matter is resolved.
"That's the league's decision," Moustakas said. "They handled it as they saw fit. As I said that day, it's part of the game and it is what it is. Just move on from it and keep playing."
Moustakas was hit in the backside by Gomez's second pitch of the bottom half of the third inning. In the first half of the inning, Royals pitcher Jonathan Sanchez hit the Indians' Shin-Soo Choo in the knee. That angered Choo because last season Sanchez, then with the Giants, broke Choo's thumb with a pitch and he spent 6 ½ weeks on the disabled list.
Each time, after Choo was hit and after Moustakas was hit in apparent retaliation, both teams charged onto the field but order was quickly restored both times. After Moustakas was hit, the umpires ejected three Indians -- Gomez, third baseman Jack Hannahan and manager Manny Acta.
Indians closer Chris Perez was also hit with a $750 fine, but his punishment had nothing to do with the on-field events. Perez was fined for a postgame message on his Twitter account Saturday night, which read: "Huge team win tonight, time for a sweep of the Royals. It's not "Our Time', it's TribeTime. P.S. You hit us, we it you. Period."
