ST. LOUIS -- On Saturday, one day after expressing frustration with how little the expanded replay system has benefited his club, manager Mike Matheny used a challenge to keep the potential tying run off the bases in the ninth inning.
With the Cardinals ahead, 9-7, closer Trevor Rosenthal allowed a leadoff double to Jean Segura and was then ruled to have hit nine-hole hitter Elian Herrera on an inside pitch. Herrera jogged to first, but Matheny asked for a review of the play.
"It was all kind of fuzzy from our perspective," said Matheny, who is now 4-for-19 in challenges this season. "What I saw is how [Herrera] didn't react right away. Our video guys did a terrific job of jumping on that before we even called up there."
A review showed that the ball struck the knob of Herrera's bat. With the call overturned, he was summoned back to the plate.
"This year there have been some situations where I have hit guys with pitches like that," Rosenthal said. "It's always borderline. When I released it, it was similar to other situations this year where I knew it wasn't going to be a strike, but I didn't necessarily think I was going to hit him. That was a big change in the situation, for sure."
Herrera went on to ground out, and Rosenthal retired the next two batters he faced to notch his 33rd save of the season.
