On April 17, 2010, Jiménez no-hit the Atlanta Braves 4–0 at Turner Field, the first no-hitter in the history of the franchise. He walked 6 batters, while striking out 7, and throwing a career-high 128 pitches (72 for strikes). He faced 31 batters in the game. The no-hitter was preserved by a diving catch in center field by Dexter Fowler in the bottom of the seventh inning. Jiménez's fastball reached 100 mph three times during the game, and it averaged 96.8 mph. During the no-hitter, Jiménez switched from the windup to the stretch delivery after issuing a lead-off walk in the fifth inning (his sixth total walk of the game). Following the switch, he didn't allow a walk for the remainder of the game. Jiménez also helped his own cause offensively, scoring Brad Hawpe with a fourth-inning single; he himself scored on a Carlos González double one batter later.
