Worth noting

• The Rockies made the expected move when they called up right-hander Tyler Chatwood to start Saturday night, returning righty reliever Rob Scahill to Triple-A Colorado Springs. It was the second callup for Scahill, who has thrown 5 1/3 scoreless innings in two big league appearances.

"He knows what he needs to do. We talked about it all spring and he's done a very good job of it," Weiss said. "It's tough to send down guys who perform. That's exactly what I told him: Just keep doing what you're doing and there's going to come a point in time when we're not going to be able to send you out."

• Weiss is happy to see center fielder Dexter Fowler regaining his swing. Fowler went into Saturday night 3-for-10 with two runs scored and a stolen base in the first two games against the Giants. He was 3-for-34 (.088) over the previous nine games.
