Flaherty's second start of the season is slated for the Cardinals' home opener April 4, Jenifer Langosch of MLB.com reports.
Flaherty, who fired four scoreless, one-hit innings in a Grapefruit League win over the Marlins on Sunday, is slated to make his season debut as the Cardinals' starter in the second game of a season-opening four-game set versus the Brewers. That will line him up to start the first home opener of his career versus the Padres. The 23-year-old right-hander enjoyed a solid spring, complementing a 1-1 record with a 2.12 ERA and .183 BAA across 17.0 Grapefruit League frames.
