Blach will not start Sunday's game against the Dodgers, Andrew Baggarly of The Athletic Bay Area reports.
The southpaw was initially tabbed to take on Clayton Kershaw in the series finale, but Friday's rainout now has Chris Stratton in line to toe the rubber Sunday. This leaves Blach without an expected two-start week, though he could be in line for a pair of starts next week depending on how manager Bruce Bochy decides to re-arrange his rotation.
