Vientos is serving as the designated hitter and batting seventh Friday versus the Blue Jays.
Vientos gets the nod here over Daniel Vogelbach, even with right-hander Chris Bassitt on the mound for Toronto. Maybe it's a sign that the 23-year-old will be in for more of an everyday role moving forward. He's primarily been limited to starts against lefties since being recalled May 17 from Triple-A Syracuse.
