Blake Treinen made his first major league start for the Nationals on Tuesday night and pitched well. He took the hard-luck loss, allowing seven hits and three unearned runs in five innings, and also collected his first career hit off reigning Cy Young winner Clayton Kershaw.

In addition to wondering where the Nationals had been hiding Treinen and his filthy 97-mph sinker, several fans, myself included, were curious about the symbol drawn to the right of the curly ‘W’ on the Nationals Park mound.

At 7:04 p.m., Treinen jogged out to a major league mound for his first big league start. He shook hands with a child who was standing at the mound as part of the pregame ceremonies. Treinen etched a “K” and “C,” with a cross in between the letters, behind the pitching rubber. The initials were in honor of his aunt, Kim Cousin, who passed away the previous day. Treinen held down his emotions.

After the game, Treinen was sent down to Class AAA Syracuse to make room for catcher Wilson Ramos, who was activated from the DL and will start today.
