Rockies prospect Daniel Winkler is headed for an MRI after injuring his elbow, Patrick Saunders of the Denver Post writes. Winkler left the Double-A Tulsa Drillers’ game against the Springfield Cardinals in the fourth inning Saturday. Winkler isn’t as well known as Rockies prospects like Jon Gray and Eddie Butler, but he has performed brilliantly this season, posting a 1.41 ERA with 9.1 K/9 and 2.2 BB/9 in 70 innings. Here are more notes from around the big leagues.
- The Mariners will likely need to make a 40-man roster move Monday, Bob Dutton of the Tacoma News Tribune tweets. Minor-league first baseman Ji-Man Choi is expected to return from a 50-game PED suspension, and he’ll need to take an active spot on the 40-man once again. Choi, 23, was off to a great start for Triple-A Tacoma, hitting .394/.500/.545 in 40 plate appearances there. He hit .295/.394/.535 in 499 plate appearances at three levels in 2013.
- The case of Travis d’Arnaud proves the difficulty involved in predicting which prospects will succeed, Andy Martino of the New York Daily News writes. The Mets optioned d’Arnaud to Triple-A Las Vegas this weekend after he hit .180/.271/.273 in 145 plate appearances so far this season. Nonetheless, many Mets officials remain upbeat about the former top prospect’s future. “He’s so athletic,” says one. “I think he will be a frontline guy, a pretty good everyday player who will hit some home runs. Is he Buster Posey? I don’t know. But do I think he can be in the big leagues on an everyday basis for eight, ten years? Absolutely.”
