While this is true, last years 12 play-off teams all had pitchers start at least 10 games (1/3 of the season) with an ERA of 4.50 or higher, 9 of 12 had pitchers start 10 or more games with an ERA of over 5.00 (Perez would have made it 10/12 but he snuck under with a starters ERA of 4.98).
Even good MLB teams struggle to fill all 5 rotation spots with quality starters. And remember a "Quality Start" translates to a 4.50 ERA ( 6 IP, 3 ER).
Possibly, though Detroit is the 2nd best staff in MLB by ERA and WHIP and best by AVG against while the ChiSox are near the bottom in MLB in those same categories.
The team is hitting better as of late, a .245/.300/.417 (.717 OPS) slash line over the last 7 days, good for 7th in the AL and 13th in MLB. Compare this to an overall .205/.285/.349 (.634 OPS) season line, good for 13th in the AL and 27th overall and maybe they have started to figure things out and make adjustments.
If the team wants to keep him stretched out as a starter, he needs to go to St. Paul to work on things and get his confidence back. Otherwise send him to the BP. Either way, SWP should be next man up.
True and I wish him continued success, but we have seen Berrios dominate like this over 4 or 5 starts in the past, only to string together 4 or 5 absolutely horrible starts. He will probably end up around his career averages of 14-10 W/L, 4.08 ERA.
Tommy John started 31 games, threw 207 innings with an ERA of 3.09 the year after his surgery (which is now named after him), that should be the bar for success...
