If you didn't win the lottery for tickets to the Opening Week Twins-Boston series, you have a second chance if you act fast.
As of Wednesday morning,
late Tuesday night, there were tickets available at twinsbaseball.com for the second game of the Red Sox series Wednesday and Thursday afternoon games against the Red Sox. I have no clue about how many there are, but even if the "sold out" sign goes up again, keep checking back. You never know what you might find.
Same goes for other regular season games where you might not have found the tickets you were hoping for when they first went on sale.
Of course, you could buy the two seats for the opener on StubHub that are being offered in Section 124 for $5,000 apiece.
