The stakes of the Texas Rangers’ four-game series with the Seattle Mariners won't define the season. But it may define the trade deadline. The Rangers (51-51) enter the series one-half game ahead of the Mariners (51-52) in the American League West. It's a close race, and the Houston Astros aren't far behind. President of baseball operations Chris Young is begging his team to give him any sign that he should go out and buy at the deadline. He's ultra-competitive and he wants to win. But the Rangers need to show him that they're turning a corner. A 2-4 post-All-Star break record won’t get it done. The good news is the Rangers have arranged the rotation in a way in which they'll have their best pitchers going this weekend. The bad news is the Mariners have done the same thing. All things considered, it should be a great series at Global Life Field. It could also define what the Rangers do to improve or pull apart this team.Here is a breakdown of the series, including how to watch, the starting pitchers, Rangers injuries and more.Seattle Mariners at Texas RangersTexas Rangers first baseman Jake Burger. | IMAGN IMAGES via Reuters ConnectWhere: Globe Life Field, Arlington, TexasSeries Schedule, TV, RadioFriday: 7:05 p.m. — TV: Rangers: CW33, can be streamed on BZZR; Mariners: Mariners.TV.Saturday: 6:15 p.m. — TV: Rangers: Fox; Mariners: FoxSunday: 1:35 p.m. — TV: Rangers: Rangers Sports Network, can be streamed on BZZR; Mariners: Mariners.TVMonday: 1:35 p.m. — TV: Rangers: Rangers Sports Network, can be streamed on BZZR; Mariners: Mariners.TVRadio: Rangers: KRLD 1080, KFLC 1270; Mariners: Seattle Sports (710 AM)Starting PitchersTexas Rangers pitcher Jacob deGrom. | IMAGN IMAGES via Reuters ConnectFriday: Texas LHP MacKenzie Gore (6-8, 4.80) vs. Mariners RHP Bryce Miller (4-4, 2.27)Saturday: Texas RHP Nathan Eovaldi (9-8, 4.21) vs. Mariners RHP Bryan Woo (7-6, 4.16)Sunday: Texas RHP Jacob deGrom (7-6, 3.76) vs. Mariners RHP Logan Gilbert (8-6, 3.38).
