ST. LOUIS (AP) — Mistakes by a few of the Seattle Mariners rookies cost them dearly. On-the-job training can be like that sometimes.
Nick Franklin got caught in a rundown and dropped a pop fly at second base for a two-base error that led to the tying run in a 2-1, 10-inning loss to the St. Louis Cardinals on Friday night. The winning run scored when the ball popped out of catcher Mike Zunino's mitt for a passed ball.
"We've got a lot of young players up here," Seattle manager Eric Wedge said. "When you're playing tight ballgames like a lot of our games and you're tight late, that's when it really shows. Whether it be defense, at home plate or on the mound, that's what we've seen a lot of."
Pete Kozma scored the deciding run and the Cardinals regained the NL Central lead by a game after Pittsburgh lost. St. Louis is 6-1 on a nine-game homestand.
Kozma entered in the eighth inning as a pinch runner, later stole third base and scored the tying run.
In the 10th, Kozma singled with two outs off Chase Ruffin (0-2). Oliver Perez walked Matt Carpenter and Jon Jay to load the bases.
Zunino couldn't handle the first pitch to Matt Holliday, with the ball rolling free and Kozma scoring on a head-first slide.
"I just sort of lost track of it heading toward my glove," Zunino said. "It's frustrating, especially when I take a lot of pride."
Franklin, the second baseman, dropped pinch-hitter Brock Peterson's towering pop fly in the eighth for a two-base error that helped the Cardinals tie it. Kozma stole third on Carpenter's full-count walk, then scored on Jay's grounder off Charlie Furbush.
"It got up in the air and the ball started traveling on me," Franklin said. "When it started traveling on me, I had to go get it and I fell short of it."
Franklin went to third on Abraham Almonte's two-out infield hit in the fifth and thought he'd score but Carpenter fielded the ball on the outfield grass and Franklin lost his footing rounding third.
"Originally they sent me to go and then I put on the brakes, and as soon as I put on the brakes I kind of slipped," Franklin said. "So I had a little bit a tough time."
Rookie Kevin Siegrist (3-1) worked around two hits in the 10th for the win. He has not allowed a run in 19 1-3 innings.
