Robertson tossed two scoreless innings to keep Minnesota in the game and was rewarded for his effort when the Twins scored three in the ninth to give him the victory.
"It was good," Robertson said. "They gave me the ball and made me authenticate my hat and all that. So it was neat. It's something I'll always remember. ... I'm pretty happy about it."
The left-hander has been racking up strikeouts since being called up in late June, as he's struck out 16 in 12 2/3 innings. He's been working on his command, as he has a 6.39 ERA in 18 appearances.
"Everything is feeling better," said Robertson. "There were about three outings in a row where my command was a little off, but I worked with [pitching coach Rick] Anderson on a few things and I think I got it squared away right now. So hopefully I'll keep throwing it well and give the team a chance to win."
