Wittgrens ERA going into tonight was 4.67. It will go up.
But is he having an off season, or is he just a bad reliever?
Before you answer, I will help with your research.
At age 31, Blake Parker had an ERA of 4.67. Both Seattle and NY figured he was bad. The Angels thought he had an off year.
Over two years and 137 appearances for Anaheim, he put up ERAs of 2.54 and 3.26.
At age 34 he had an ERA of 4.21, and by mid season Minnesota thought he was bad, and let him go. Philadelphia picked him up and he was worse...5.04 ERA. But Philly thought he had an off year, so they brought him back.
His ERAs the last two years have been 2.81 and 2.54.
Parker is not an anomaly. His is the normal story of a career middle reliever.
