[1] Gómez made his Major League debut that afternoon as a defensive substitution at first base for Adrián González and struck out in his only plate appearance.

On July 4, the day after being recalled for the second time in 2012, Gómez recorded his first major league hit against the Oakland Athletics.

He also tied for second with 24 home runs, while leading the league in slugging percentage (.589) and ranking fourth in RBIs (74) and total bases (228).

[10] Gomez put to rest any concerns on whether he could make a smooth transition by hitting .327 with four homers and 33 RBIs in his first month.

[9] He then went on to reach base at least once in each of the first 27 games of the season, breaking the franchise record of 24 that had been held by Yutaka Wada, the Tigers’ current manager, since 1997.

In the September 20 game against Chunichi, he scored 2 singles and a solo homer, and became the first foreign player in franchise history to record over 100 RBI in their first year in the NPB.

[12] He joined Randy Bass (134 in 1985, 109 in 1986), George Arias (107 in 2003), and Craig Brazell (117 in 2010) as the only foreign Hanshin players to notch 100 or more RBI in a season.

Gomez played a key role as the Tiger's clean-up hitter during the postseason Climax Series against their archrivals Yomiuri Giants.

[17] In January 2017 he had contract negotiations for the Korean Samsung Lions, but the club refused to close the deal after Gomez failed his medical test with problems regarding his knees.
