Julio Urias lasted just 2 2/3 innings in his Los Angeles Dodgers debut, when he became the first teenage starting pitcher in the major leagues since Seattle's Felix Hernandez in 2005. Wearing striking white glasses and making theatrical jumps over the third-base line, his debut drew comparisons to the early Dodgers days of fellow Mexican pitcher Fernando Valenzuela, who joined Los Angeles as a reliever in 1980 and sparked ''Fernandomania'' as a brilliant starter the following season. ''Naturally, that's the comp, but to compare to anyone to Fernando and what he did after you look at the impact he made on the Mexican community as well as the Dodgers and baseball in general is unfair,'' Dodgers manager Dave Roberts said before the game.
