Noah Syndergaard has been terrific through his first four starts this season, pitching to a 1.73 ERA and 30 strikeouts in 26 innings.
The New York Mets right-hander's average fastball velocity is 99.6 mph, but it is his control that has him chasing history.
He has yet to walk a batter in 2017 and only 16 pitchers (12 starters) have opened a season with more walk-less innings.
Syndergaard is scheduled to start on Wednesday against the Atlanta Braves and with seven innings pitched without a walk, he would move into a tie for second-place on the all-time list. The leader, Pete Alexander of the Chicago Cubs, tossed 51 innings to begin the 1923 season without issuing a walk.
