WASHINGTON — A day after Washington pitcher Doug Fister said he recently had surgery to remove skin cancer from his neck, Nationals manager Matt Williams says players and coaches are very aware they’re at risk for the disease.

Williams says it’s a big issue in baseball because there’s constant exposure to the sun.

Fister pitched six innings Friday in a 10-3 loss to San Francisco, ending Washington’s 10-game winning streak 10-3.

Fister was asked after the game about what appeared to be a cut on his neck. He said he had some skin cancer removed a couple of days earlier, and that he was OK.

Williams said there was no thought given to Fister skipping his turn because the doctors said there were no issues.

Indians place Gomes on DL: The Indians placed catcher Yan Gomes on the seven-day concussion disabled list.

Gomes, hit in the mask Thursday after a pitch deflected off Minnesota’s Kurt Suzuki, was still experiencing symptoms after taking part in some light activity. Indians manager Terry Francona said the team is taking a cautious approach and doesn’t want to rush Gomes back into action.

Tanaka tests elbow against batters: Masahiro Tanaka took another positive step toward returning to help the Yankees make a run for a playoff berth, facing batters for the first time since he was sidelined six weeks ago with a partially torn right elbow ligament.

In front of several dozen reporters and photographers, the Japanese ace threw 35 pitches in a two-inning simulated game and reported no problems with his elbow.
