New York Yankees shortstop Didi Gregorius left Sunday's game against the Toronto Blue Jays with a bruised left heel.David Lennon ofNewsdayreported the news Whitey Herzog Jersey , noting Gregorius will undergo further testing. Manager Aaron Boone told reporters the bruise is "pretty significant" and that Gregorius could land on the disabled list.The 28-year-old has been fairly durable since joining the Yankees, playing 155 games in 2015, 153 games in 2016 and 136 games in 2017.Gregoriusturned the corner the last two seasons from an offensive production standpoint, slashing .287/.318/.478 with 25 home runs and 87 RBI in 2017 after drilling 20 long balls the year prior.His prowess at the plate was one reason the Bronx Bombers advanced to Game 7 of the American League Championship Series before losing to the eventual champion Houston Astros last season.He has followed with a .268/.332/.481 slash line to go with 22 homers and 73 RBI in 2018.The left-handed hitting Gregorius' presence helps balance a New York offense featuring righties Aaron Judge, Giancarlo Stanton and Gary Sanchez when everyone is healthy, but there are still enough pieces to tread water until the shortstop is ready to return.The Yankees can turn toward Gleyber Torresat shortstop with the Dutchman out and rely on Neil Walker or Ronald Torreyesat second base in the meantime. CLEVELAND — The Cleveland Indians and their improved bullpen will host the Kansas City Royals on Tuesday night at Progressive Field in the second game of a three-game series.The Royals won the first game 5-1 on Monday to extend their season-high winning streak to six games.

We’ve allowed him to face right-handed hitters Orlando Cepeda Jersey , and he’s been great. It doesn’t matter what inning we bring him in. We use him when it makes the most sense. When he’s in the game, there’s a lot of importance going on.”Tuesday’s pitching matchup features Royals left-hander Danny Duffy and Indians right-hander Mike Clevinger.
