Consider these two pitchers in their four most recent appearances.
Pitcher A: 31 innings pitched, 15 hits, 26 strikeouts, 0.87 ERA, 0.68 WHIP.
Pitcher B: 24 2/3 innings pitched, 11 hits, 29 strikeouts, 0.28 ERA, 0.69 WHIP.
Pitcher A is Chicago Cubs ace Jake Arrieta, who some baseball pundits suggest is in the midst of one of the greatest pitching tears in Major League Baseball history and whose line above included a no-hitter against the Cincinnati Reds.
