The bad news about the Orioles starting rotation this year is that it was among the worst in baseball with a collective 4.72 ERA. Worse news is that every single one of the starting pitchers who contributed to that number could be back next year.
Any way that you want to break it out, the numbers are ugly and the prospect for next season looks grim. For instance, of the eight starters who started at least ten games for the team, five of them had an ERA over 5.00. That accounts for 84 starts made this year, a bit more than half of the season started by pitchers who were seldom competitive.
