Home runs from Corey Seager (Rodriguez’s first round HRD opponent) and Leody Taveras reduced the deficit and made it 4-3. It all went in vain after Rodriguez hit his first career grand slam which put the Mariners 8-3 up and sealed their 12th straight win.Rodriguez has 16 homers to his name this season.The timing couldn't have been any better. Rodriguez was revealed as one of the participants for this year’s Home Run Derby a couple of days ago.

There are a few favorites, and Rodriguez, who is the sixth seed, understandably isn’t one.Brycen@BBOYnHisBag@saneguy2k @Mariners @JRODshow44 No, he’s the 6th seed for a reason@saneguy2k @Mariners @JRODshow44 💀💀No, he’s the 6th seed for a reasonDefending two-time HRD champion Pete Alonso is an overwhelming favorite to make it three in a row. He would become the first ever to do so. Philadelphia Phillies slugger Kyle Schwarber is another favorite for the crown, having lost the 2018 final to his now-teammate Bryce Harper.Rodriguez is a rookie, but that wouldn't deter him or the ones backing him to win. Alonso was a rookie in 2019. Not only did he win it, but he won it back-to-back. New York Yankees superstar Aaron Judge was a rookie too when he won in 2017.muskabeatz listener@saneguy2k@Mariners @JRODshow44 HES WINNING THAT SHIT TOO1@Mariners @JRODshow44 HES WINNING THAT SHIT TOO⚡️@ElitePrez@Mariners @JRODshow44 Way to 1 up Seager28@Mariners @JRODshow44 Way to 1 up SeagerThe Home Run Derby takes place at 8:00 p.m. ET on Monday, July 18, at Dodger Stadium in LA.
