Major League Baseball saw 10 starting pitchers go at least seven innings while allowing three hits or fewer, according to the Elias Sports Bureau.
Such a feat, combined across a third of all the starting pitchers on Sunday, would be a new MLB record.
One of the usual suspects to make the list included veteran Adam Wainwright of the St. Louis Cardinals, who also became the first pitcher to reach five wins this season.
The Cards shut out the Pittsburgh Pirates 7-0 with Wainwright's famous curveball allowing three hits in eight innings, recording 10 outs.
Another top performer was Johnny Cueto of the Cincinnati Reds, who struck out 11 in eight scoreless innings. However, his performance didn't helps the Reds, who lost 1-0 to the Atlanta Braves.
That was because Braves pitcher Julio Teheran also threw eight scoreless innings.
James Shields (Royals), Garrett Richards (Angels), Ryan Vogelsong (Giants), Collin McHugh (Astros), Dillon Gee (Mets), Jason Hammel (Chicago Cubs) and Ian Kennedy (San Diego Padres) complete the list of the record breakers.
