Heat head to Memphis after ‘breakthrough’ in Dallas

The Miami Heat are trying to ride a wave of momentum as they head to Memphis to face the Grizzlies on Monday night. Miami defeated the surging Dallas Mavericks on Saturday, 122-118 in overtime. It was the fourth time this season the Heat earned a split in back-to-back games -- they lost Friday to the Western Conference-leading Los Angeles Lakers -- but coach Erik Spoelstra called it a step forward.
