Mets left fielder Dominic Smith collided with shortstop Amed Rosario on a pop-up that led to the game-winning run to score in the top of the 13th inning in Monday's 2-1 loss to the San Francisco Giants at Citi Field.
"It sucks, especially the way this year has been going," Smith said after the game.
With runners on the corners and two outs, Brandon Crawford popped a Tyler Bashlor fastball into shallow left field. As Rosario backpedaled, Smith came in and bumped into Rosario as the ball landed on the grass and allowed Andrew McCutchen to score the go-ahead run.
"It's inexperience," manager Mickey Callaway said after the game of Smith's error. "He hasn't done that often. He'll get better at it. I think that's one of the reasons we're trying to get him reps when he's in Triple-A in left. I think that he's got a learning curve that he's got to go through to play left field the way that he's capable of playing."
Smith's error was one of three the Mets committed in the game. Rosario dropped a foul ball earlier and Bashlor had a throwing error earlier in the top of the 13th inning.
"That play, I was playing deep because it's late in the game. It's a high fly ball and it's pretty shallow, so you're running in hard and kind of take your eyes off it," Smith said after the game. "You don't really know where the infielder is and that's pretty much what happened."
The 23-year-old Smith has spent most of his career as a first baseman but has spent more time in the outfield. With Triple-A Las Vegas, Smith played 18 games (155 innings) in left field and committed one error. Entering Monday's game, he hadn't committed an error in 59 1/3 major-league innings in left.
