According to Elias

Francisco Liriano

Twins lefty Francisco Liriano struck out 15 batters at Target Field but allowed a grand slam home run to Jonny Gomes in the fourth inning which led to a 6-3 loss to the A’s last night. Liriano is the first pitcher since 1900 to register at least 15 strikeouts and allow a grand slam in the same game. Liriano registered the ninth 15+ strikeout performance in the Twins/Senators franchise history, but he is the first to do that in a losing effort. Source:Elias
