The 28-year-old Mexican striker scored his 14th Bundesliga goal of the season in a losing cause for Bayer Leverkusen.
Despite his club failing to secure any points, Javier Hernandez scored a consolation goal in Bayer Leverkusen's 3-1 loss at Mainz on Sunday.
The Mexican international tallied in the 65th minute, after the home side had already scored all of its goals. The second-half strike — a header from point-blank range after a long free kick was redirected toward Hernandez inside the box — was his 14th Bundesliga goal of the season, good for fourth place in the league's Golden Boot race.
