A look at what’s happening around the majors today:MOOKIE MANIAMookie Betts tries to follow up his first career cycle when Boston opens a series at Baltimore. The AL MVP contender homered off Ken Giles in the ninth inning Thursday to complete his first career cycle Bradley Zimmer Jersey , though the Red Sox still lost 8-5. A trip to Camden Yards doesn’t figure to slow Betts — he’s hit 13 homers there in 35 games, by far his most in any stadium other than Fenway Park.

Jansen has dealt with an irregular heartbeat in the past, and manager Dave Roberts said the right-hander will visit his cardiologist in LA. Roberts said the team is “holding out hope it’s not too serious.” Roberts didn’t know if the team would make a roster move in Jansen’s absence.CARLOS COMES BACKCarlos Correa is expected back in the lineup for Houston. The star shortstop has been out with lower back soreness since June 25. Correa completed a rehab assignment with Double-A Corpus Christi on Wednesday and was in Houston for a scheduled day off Thursday. Correa is batting .268 with 13 home runs and 49 RBIs.BOLSTERED BULLPENThe Athletics have charged into the AL playoff picture with a never-say-die lineup, but Oakland is looking to make a name for keeping leads, too. Fernando Rodney may join the team Friday after being acquired via trade from Minnesota on Thursday night. The longtime closer joins a deep bullpen led by Blake Treinen, Lou Trivino and former Mets closer Jeurys Familia. That quartet could prove pivotal if Oakland winds up in the AL wild-card game.
