CINCINNATI -- Reds starter Mat Latos left no room for nuance when discussing the team's season-ending loss to the Giants in the National League Division Series on Thursday.
Latos was on the mound for all six of the San Francisco Giants' runs, and threw the pitch that Buster Posey smashed into the left-field seats for a grand slam that stood up as the decisive blow. With a 6-4 Reds loss, Latos' debut season in Cincinnati was over.
He was standing at his locker when the clubhouse doors opened and reporters filed in.
"I let a couple of things get to me that shouldn't have," Latos said. "I made a mistake to Posey and he hit a grand slam. The only thing I can really say is I let down everybody. I let down the team, most importantly and the front office and the fans. I let things get to me. One hundred percent of this game is on me. I [messed] it up."
He had dueled the Giants' Matt Cain through four scoreless innings, but came unglued after San Francisco's leadoff man in the fifth, Gregor Blanco, punched a 1-2 fastball to left field for a single.
"It was aggravating that he got a hit off of me when I pretty much had him beat," Latos said.
The Giants took the lead when Latos threw a fastball down the middle to Brandon Crawford for an RBI triple. Two batters later, Angel Pagan reached on a run-scoring error charged to shortstop Zack Cozart, and Latos' aggravation increased with a four-pitch walk to Marco Scutaro.
Pablo Sandoval loaded the bases with a single, and Posey un-loaded them with a grand slam. It was the first off Latos in the right-hander's Major League career.
It was Latos' final batter. Reliever Sam LeCure was summoned to finish the inning.
Latos was 14-4 with a 3.48 ERA during the regular season, but cited plenty of room for improvement.
"Mental improvement," he said. "If I don't let those little things get to me, who knows now that if they score two runs and we win 3-2? Or they score three runs and we win 4-3? It was a mental error on me. I'm not making excuses. I screwed it up. This game is 100 percent on me. I let down my teammates, and that's what bugs me the most right now."
