Every year, every playoff team but one sees its season end with a loss. Only a few of those can say it was a great run. The up-and-down '21 Red Sox had multiple great runs -- until they stopped scoring them. Thankfully, no one single play blew the pennant, so future Fox telecasts won't ever have time to replay three games worth of batters bouncing sinkers, popping up heaters, and whiffing on dirtballs.
The manager didn't swing a bat the entire postseason. He wasn't a genius when they slammed salamis, or a bum when they left dozens on base. But for anyone who thinks pitching moves are to blame, here are some stats on the two bullpens in this ALCS (using ERA, even though it excuses a pitcher's own errors, like Robles throwing away a pick-off): four Red Sox relievers had ERAs over 10 and five others were 4.50 or gave up late home runs. Houston had three relievers with ERAs of 0.00, and five others at 3.00 or lower.
