Tyrone Tracy Jr. is emerging as the frontrunner for the New York Giants' backup running back position behind Devin Singletary, thanks to his unique skill set developed from his previous experience as a wide receiver. With an impressive college career at Purdue, where he rushed for 716 yards and eight touchdowns, Tracy's ability to catch passes out of the backfield could be valuable in the Giants' offense, which may utilize short passes as an extension of the running game. Meanwhile, Tyler Fitzgerald of the San Francisco Giants has been named National League Rookie of the Month after a stellar July, hitting .321 with eight home runs and 15 RBIs. Lastly, Kamari Lassiter, a rookie cornerback for the Houston Texans, is vying for a starting position and is noted for his strong performance in training camp against established players like Stefon Diggs. These developments highlight the promising potential of rookies across various teams in the NFL and MLB.
