The New York Mets placed left fielder Yoenis Cespedes on the 10-day disabled list Saturday because of a strained right hamstring, possibly ending his 2017 season.The Mets activated infielder Jose Reyes from the disabled list, called up outfielder Travis Taijeron from Triple-A Las Vegas and optioned right-hander Kevin McGowan to their Triple-A team.Cespedes left Friday night's game 4-2 win over the Washington Nationals in the first inning after he hobbled around third while running the bases. He is hitting .292 with 17 homers and 42 RBIs in only 81 games this year because of various injuries.Reyes, who was on the disabled list since mid-August because of a sore left ribcage, is hitting .223 with nine home runs and 39 RBIs in 114 games. Taijeron is batting .272 with 25 home runs and 78 RBIs in 125 games for Las Vegas.

It spoiled an exhibition season where he batted .451 and seemed ready to assume the role of New York's regular first baseman after missing last season recovering from shoulder surgery.Bird never got going and was hitting .100 (6-for-60) with one homer and three RBIs to go along with 22 strikeouts in 19 games. The Yankees decided to place on the disabled list May 2, hoping sufficient rest would cure the ankle. Instead, Bird's first rehab stint in the minors was cut short and he underwent ankle surgery on July 18.To make room for Bird on the roster, first baseman Tyler Austin was optioned to Triple-A Scranton/Wilkes-Barre. Austin batted .233 in 10 games for the Yankees.--The Cleveland Indians selected the contract of veteran left-handed relief pitcher Craig Breslow from Triple-A Columbus.The 37-year-old has split this season between the Indians and the Minnesota Twins organizations, signing as a minor league free agent with Cleveland on Aug. 4.Breslow was 1-1 with a 5.23 ERA in 30 games with the Twins this season around a stint on the disabled list because of ribcage soreness. He was designated for assignment by the Twins on July 24 and later released.The Indians also optioned left-hander Ryan Merritt to Columbus and designed right-hander Diego Moreno for assignment.
