Steven Matz complained ofleft forearm tightness after the team's 25-4 loss against the Washington Nationals redsoxproshops.com/authentic-fred-lynn-jersey , according toAnthony DiComo of MLB.com."I think we need to get him checked out just to make sure that's not the case," Callaway said.Matz downplayed any injury concerns, telling reporters he thought he was just going through a normal "dead-arm phase" and that he feels "healthy and good," adding that "it's hard to describe."Matz gave up seven runs and eight hits in his shortest outing of the season for the Mets Tuesday night, as he was pulled after getting just two outs in the first inning.Any injury is particularly concerning for Matz, who has suffered a long list of them in his career, dating back to having Tommy John surgery in 2010.As DiComo detailed, Matz"also underwent operations to remove bone spurs from his left elbow in 2016 and to reposition the ulnar ligament in his forearm the following year. Since reaching the Majors in '15, Matz has also spent time on the disabled list due to a torn left lat muscle, a left shoulder impingement and left elbow inflammation."Coming into this season, the most starts Matz has ever made in his career was 22 in 2016, though he's set to surpass that in 2018 Wade Boggs Jersey , with 21 starts already in the books.In what has been a disappointing season in basically every capacity for the Mets, Matz has been up-and-down as well, posting a 5-9 record with a 4.35 ERA, 1.34 WHIP and 99 strikeouts in 107.2 innings. He's on pace to surpass his previous career high in innings (132.1), however, a factor the Mets are keeping in mind down the stretch."We have to make sure that we understand that and take every precaution necessary to keep them on the field as much as possible," Callaway said of Matz,Zack WheelerandJacob deGrom, who are all on pace to set career highs in innings.At this point, there's basically zero incentive for the Mets to keep Matz on the mound if there's even the slightest concern about his health. The team is 44-60, with any postseason hopes long abandoned. The long-term health of Matz and his counterparts on the mound is far more important than any late-season wins. A look at what’s happening around the majors today:NO OPENERS NEEDEDCy Young Award winners Justin Verlander and Corey Kluber will start the AL Division Series between the Astros and Indians at Minute Maid Park in a matchup that figures to buck the October trend of bullpen “openers.”Verlander, a 14-year veteran redsoxproshops.com/authentic-carlton-fisk-jersey , believes the AL West champion Astros and AL Central champion Indians have the top two rotations in the AL. He thinks the performance of each team’s starters will be paramount to success.“Us and the Indians probably being 1 and 2, however you like to slice it, us and them, them and us,” he said. “Pick your poison. We both have very defined starters who have a great track record and have good stuff. This should be a really fun series.”ON SALEChris Sale waited eight years to make his first postseason start and then another 365 days for a chance to put that memory behind him. The Red Sox left-hander will open Game 1 of the AL Division Series against the New York Yankees, one year after he was bombarded by the championship-bound Houston Astros in his playoff debut.“Last year, obviously, I got my feet wet. Didn’t do too well. But sometimes you learn from the bad more than the good,” Sale said Thursday, a day before the AL East rivals open their best-of-five series.He’ll oppose J.A. Happ at Fenway Park as the Yankees and Red Sox begin their first postseason series since the 2004 AL Championship Series.THE ACE AWAITSClayton Kershaw pitches Game 2 of the Dodgers‘ NLDS against Atlanta showing no signs that he’s miffed about being passed over for Game 1. Los Angeles manager Dave Roberts went with Hyun-Jin Ryu in the series opener at Dodger Stadium instead of the longtime face of the franchise, setting up Kershaw to pitch on five days of rest. Ryu responded with seven sharp innings in a 6-0 win.Roberts says the vibe with Kershaw is “great.” Kershaw can opt out of the final two years of his contract after the World Series.“Obviously, it’s a huge sacrifice for him Pedro Martinez Jersey ,” Roberts said. “But to not let it influence his mind or psyche, that doesn’t surprise me.”Atlanta will counter with veteran Anibal Sanchez.QUIET COLORADOThe Rockies’ bats have gone mostly silent this October, a slump try to snap against Brewers starter Jhoulys Chacin in Game 2 of their NLDS at Miller Park. Colorado had just four hits in a 3-2, 10-inning loss Thursday, two days after beating the Chicago 2-1 in 13 innings in the wild-card game.At least they’ll get a respite from Milwaukee’s vaunted bullpen. Relief pitcher Brandon Woodruff pitched three hitless innings as the “opener” in Game 1 and the bullpen cruised until Jeremy Jeffress‘ ninth-inning hiccup. Chacin will be pitching on three days of rest against left-hander Tyler Anderson.FUTURE LOOKThree Cuban prospects, including top international free agent Victor Victor Mesa, will try out for major league scouts at Marlins Park. Also participating will be Mesa’s brother, Victor Mesa Jr., and pitcher Sandy Gaston. All teams are invited to attend. The Mesas, both outfielders, were recently declared free agents by Major League Baseball and can be signed by any team.
