Brett Baty lands on the IL with a strained right oblique, ending his regular season and clouding postseason odds. MRI will determine return prospects. Baty, who hit .254 with 18 homers in 130 games as an everyday infielder, is replaced by Jared Young while Ronny Mauricio slides back to third. The Mets rely on in-house depth in a high-stakes series with Miami as they chase a playoff berth and monitor Baty's status for October.
