What happened: The Toronto Blue Jays head into Seattle to face the Mariners in a matchup of American League contenders, with the game airing nationally on MLB Network. Kazuma Okamoto leads Toronto into T-Mobile Park, where Randy Arozarena and the Mariners await riding a three-game winning streak.

Why it matters: Seattle enters at 45-43 and has won three straight, while Toronto sits at 41-46 and is fighting to climb back into the AL race in the season's second half. Every head-to-head meeting between AL hopefuls carries added weight with the standings this tight at the midpoint. Okamoto has been swinging a hot bat and remains central to Toronto's push.

By the numbers: Seattle is 45-43 this season, averaging 4.1 runs scored and 3.9 allowed, and has won three in a row (last five: W-W-W-L-L). Toronto is 41-46, scoring 4.1 runs per game while allowing 4.4, and went W-L-W-L-L over its last five before winning its most recent game.

What to watch: First pitch comes in Seattle, where the Mariners will try to extend their winning streak to four and the Blue Jays look to build momentum heading deeper into July.
