Neal Cotts has masqueraded as a major leaguer pitcher long enough. His 4.50 ERA isn’t a true indication of how bad he is pitching but rather a testament to the pitchers who relieve him putting out the fire he has started thus not hurting his ERA much.
His WHIP (walks, hits per innings pitched) of 3.00 ranks him 386th among 405 major league pitchers. If he pitched nine innings with the same stats he has for 4 innings he would be giving up 15.8 hits per nine innings not exactly something to call home about to say he pitched a 15 hitter. 11.3 walks per nine innings is not so hot either.
In 4 innings he has given up 7 hits, 5 walks and hit a batter for 13 baserunners in 4 innings or enough to load the bases three times.
Baseball-reference compares his stats with such luminaries as:
He will have to start pitching a lot better to make it to the Hall of Fame and then he will have to decide whether to wear a Cubs cap or a White Sox cap on his plaque.
