West Notes: Gattis, Diamondbacks, Cain, Span

Astros catcher and designated hitter Evan Gattis appears headed to the disabled list after receiving a concussion diagnosis yesterday, writes Brian McTaggart of MLB.com. The end of a Corey Dickerson swing caught Gattis in the head on Thursday. The team currently plans to option first baseman A.J. Reed to Triple-A Fresno and promote third baseman J.D. Davis, who was hitting .282/.345/.527 in the high minors this season. The team will have to make another move to add a catcher if it does place Gattis on the DL, however. Here’s more from the West divisions.

• The Diamondbacks’ rotation has gone from second worst in the Majors last year to second best this season, MLB.com’s Mike Petriello notes. Petriello credits big improvements in the Snakes’ outfield defense and catching, along with Robbie Ray’s breakout, and Taijuan Walker’s addition. He also notes that Zack Godley moved from relieving to starting for the big club this year, while Archie Bradley did the opposite; both moves had a big impact on the fortunes of Arizona’s starting pitchers.
• The 42-69 Giants are finding new roles for two veteran players, as Andrew Baggarly of the Bay Area News Group noted earlier this week. The team will use Matt Cain, who’s in the midst of a third straight season with an ERA above five, as a long reliever until his contract expires at the end of the season. (The team does have an option on Cain for 2018, but almost certainly won’t exercise it.) Chris Stratton will take Cain’s place in the rotation. And the team has told center fielder Denard Span it plans to move him to left field, although he might not actually make that move until next spring. Span, for his part, since he has “no problem” with the move, as John Shea of the San Francisco Chronicle writes. “If you look around the league, you don’t see too many everyday center fielders who are 33 years old,” he says. “By the same token, I think I can still play center.”
