A look at what’s happening around the majors today:The Cubs will try a closer-by-committee approach down the stretch after learning Pedro Strop is out for the rest of the regular season because of a strained left hamstring. Strop Ferguson Jenkins Jersey , who had posted 11 saves since closer Brandon Morrow went on the disabled list in July, hurt himself trying to beat out a double-play grounder this week.On Friday night, Jorge De La Rosa worked around a double and walk in the ninth inning for his first career save, preserving a 3-2 win over Cincinnati at Wrigley Field. Cubs manager Joe Maddon said he envisions calling on veterans including Steve Cishek, Justin Wilson and Jesse Chavez to finish games.ONE MOREMike Clevinger starts at Progressive Field as Cleveland tries to clinch its third straight AL Central title. The Indians have a magic number of one — they can wrap up the division with a win over Detroit, or a loss by Minnesota at Kansas City.RATS!The New York Mets had an unwelcome visitor to their dugout as their series opened at Fenway Park: a rat that sent the players scurrying away. No word on whether it was the same one that rattled the Red Sox in their dugout on Tuesday night. Boston players paid tribute to their guest Friday night with a (presumably fake) rat skeleton on their dugout railing.GETTING CLOSERInjured Yankees closer Aroldis Chapman is set to throw a bullpen session, then will pitch a simulated game on Monday. If all goes well, he could be activated in the middle of next week. The New York lefty hasn’t pitched in a game since Aug. 21 because of left knee tendinitis.THEY ALL COUNTAll during the month http://www.rangersfanproshop.com/authentic-jason-grilli-jersey , a lot of September call-ups from the minors will be getting their first hit in the majors. It happened for Mitch Walding of the Phillies on Friday night when he homered — off Miami catcher Bryan Holaday, who was pitching in a blowout. Walding had been 0 for 14 with 10 strikeouts in the big leagues.“I was speechless,” Walding said. “Probably one of the happiest moments I’ve ever had in my life. “It was very special and something, obviously, I’ll never forget the rest of my life.”FOR STARTERSThe A’s and Rays, two of the primary teams using relievers as openers to start games, will employ the strategy against each other for the first time. Tampa Bay will go with Ryne Stanek (2-3) while Oakland counters with Liam Hendriks (0-1) at Tropicana Field.“It’s just trying to take advantage of what you have,” Athletics manager Bob Melvin said. Throughout his time with the Red Sox Ryan Rua Jersey , Eovaldi has proved he is more than capable of putting together quality starts, as he conceded zero earned runs in five starts for Boston.In his career at Minute Maid Park, he has given up six earned runs, four of which came in the June meeting with the Astros.One concern the Red Sox could have about Eovaldi is his record after more than six days of rest, which sits at 5-9 in 27 starts.If he can shake off the rust and retire Houston's sluggers in order to start the game, he should settle into a rhythm and hand the Red Sox a similar outing to the one he produced at Yankee Stadium.However, if Houston's bats wake up in the opening third of the game, Boston manager Alex Cora will be forced to go to his bullpen fast and end up stuck in a tricky rotation situation with David Price already struggling.Which Houston Bats Will Wake Up?Only three Houston players recorded two or more hits at Fenway Park Drew Robinson Jersey , with Springer leading the ball club with three base knocks.One of the reasons why the Astros hit .188 in the first two games of the ALCS was the 15 walks they were issued, with Bregman drawing six of them.Altuve's struggles at the plate didn't help Houston's offensive rhythm either, as the second baseman went 1-for-8 in Boston.At some point, a handful of players in the Houston lineup are going to break out at the dish, and that could happen as soon as Game 3 since they'll be in familiar surroundings.Springer, who has an 11-game postseason hitting streak, needs to be the catalyst at the top of the order, but he's going to need either Altuve or Bregman to bust out a clutch hit in order to take full advantage of having runners in scoring positions.David Dermer/Associated PressIf Bregman continues to reach base by way of walks http://www.rangersfanproshop.com/authentic-alex-claudio-jersey , Yuli Gurriel has the opportunity to be the breakout star of the Houston lineup.He has two hits in nine at-bats in the ALCS with one home run and three RBI.The 34-year-old was one of Houston's top hitters in September, when he recorded 10 multiple-hit games in the final month of the regular season.The first baseman carried that form into the postseason, as he has one hit in four of the five games he's started.With his team in need of a wake-up call at the plate, Gurriel will drive in at least two runs and set the tone for the bottom half of the order to make contributions while keeping the Boston pitching staff out of a rhythm.
