Yamamoto tossed Schmitt a 1-1 splitter; Schmitt sent the offering towards Glendale. Schmitt’s grand slam wasn’t just his second home run of the season, but his second home run since stepping in for Matt Chapman, who will be on the injured list for several weeks due to right hand inflammation.

Yamamoto walks a season-high five in just 4⅔ innings – including three in a span of five batters before Casey Schmitt’s grand slam – and San Francisco takes the series opener, 6-2.
