Flores racked up an ERA of 5.62 that year (2006) for the Cardinals. But he is likely more remembered there for his work in the postseason: Six scoreless innings in seven appearances, including the win in Game 7 of the NLCS.

Shades of Dan Schatzeder of the 1987 Twins — 6.39 ERA during the regular season for the Twins, winning pitcher in Game 6 of the World Series.

Flores isn't a great pitcher. He's not even particularly good against left-handed hitters. (See that photo above? That's Garrett Jones, once a member of the Twins and a left-handed hitter, running out a home run earlier this month against Flores.)

Flores, as viewed from the stats, may not be worth adding. The Rockies dumped him for a reason. The argument for him, as voiced by manager Ron Gardenhire, is traditional scouting (and perhaps a bit of wishful thinking):

Ron Mahay is done for the season (the Twins put him on the 60-day DL to make room for Flores on the 40-man roster). The prognosis for Jose Mijares is uncertain. Glen Perkins isn't a proven option against lefties. There's no southpaw in the minor league system capable/deserving of the chance.
