On April 11, 2015, in his first start of the season, Jimenez pitched 7 shutout innings, against the Toronto Blue Jays. He allowed only two base runners, a single by José Reyes in the 4th, and a walk to him in 6th, and struck out 8. On April 17, 2015, in a start against the Boston Red Sox, Jiménez was ejected for the first time in his career by home plate umpire Jordan Baker. Jiménez had hit Pablo Sandoval in the right shoulder. Baker deemed the hit by pitch intentional, after Sandoval had slid into second baseman Jonathan Schoop, to break up a double play.
