The end of the 2017 Cardinals season meant many things to many people. There was a 10th straight winning season by the club but a second consecutive season without October baseball, unless you count Sunday, which was the first of the month, when there were scant few highlights in a 6-1 loss to the Milwaukee Brewers. One, though, was a spotless, two-strikeout inning by reliever Sam Tuivailala, who has gained a potential toehold for next year as part of a revamped bullpen. To Tui, the end of the season meant that he no longer could be optioned to the minors by the Cardinals or anybody else. Players can be optioned as many times as the clubs wish in a season and have it be counted as only one of the three option years available to them. Tuivailiala wore out I-55 this year, being sent out three times —and brought back three times. But now the Cardinals have used up their three option years. Like Tyler Lyons this season, Tuivailala cannot be sent out without passing through waivers, and the way he has progressed, that doesn’t seem very likely. His lease on his apartment in Memphis, which he kept all season, is up. And while he liked it well enough — “It had a bed and a pool,” he said — he is not eager to return. Excluding September, and, of course, October, the 25-year-old Tuivailala spent parts of every month this season in Memphis. “I guess that’s not really a good bucket list,” he said. But Tuivailala also spent at least parts of every month, including September and October, in St. Louis, which is more significant.
