Headed toward a potentially epic October, the best teams in the National League don’t just march on. They get better.

Major League Baseball Advanced Media just announced a limited-time offer of just $17.99 for the yearly subscription to watch live out-of-market games with MLB.TV Premium. That is in honor of the 18 Deadline-day deals we witnessed on Monday, the most in the Majors since at least 1995.

You can practically see the trail of smoke coming off the ball.

This year’s non-waiver Trade Deadline was an absolute whirlwind, with 18 deals made across the Majors — the highest total since 1995. Now that Aug. 1 has come and gone, let’s examine the four teams that improved the most.

The Rangers stole the headlines at the Trade Deadline for the second year in a row, but it was the Yankees who showed a whole new side to their existence — they went shopping for the future, and general manager Brian Cashman earned rave reviews for his first plunge into the rebuilding market.

Happy trade season, everybody.

Alexi Amarista exited Monday’s game vs. the Brewers with a left hamstring strain in the bottom of the fifth inning.

Exactly three weeks after undergoing left knee surgery, Red Sox closer Craig Kimbrel was activated for Monday’s game in Seattle.

Scott Feldman was not supposed to pitch on Monday night, but after the Blue Jays ran out of pitchers when the game went deep into extra innings, the club had no choice but to call his name.

Andrew Benintendi’s meteoric rise through the Red Sox’s farm system has landed him in the Major Leagues less than 14 months after being drafted.

Once Monday afternoon’s non-waiver Trade Deadline chaos settled into quiet, after the Mets acquired Jay Bruce from the Reds and the Yankees dealt Carlos Beltran to Texas, a sold-out crowd piled into Citi Field for what was theoretically still the day’s main event.

A day later and in a different city, the Red Sox again pulled out a dramatic victory, this time edging out the Mariners, 2-1, on Monday at Safeco Field.

Washington began August with a strong start, pummeling Arizona, 14-1, at Chase Field as Stephen Strasburg became the first pitcher in the Majors with 15 wins. The Nationals’ right-hander collected as many hits (three) and drove in as many runs (one) as he allowed in his six innings.

The Blue Jays and Astros flirted with history Monday, combining for 40 strikeouts — 22 by Houston, 18 by Toronto — in a 14-inning marathon at Minute Maid Park, a 2-1 Astros win.

Yangervis Solarte had a two-run single to highlight a five-run fifth inning Monday as the Padres defeated the Brewers at Petco Park. Hernan Perez had a two-run home run for Milwaukee and Chris Carter added a solo shot.

Amid a season spent on the outskirts of the postseason race, the Yankees entered the Subway Series a team championing its suddenly bright future. A series of trades that spelled the exits of much of their core, general manager Brian Cashman said, were designed to position the Yankees to compete for years to come.

Cubs No. 21 prospect Rob Zastryzny was among the top prospect performers in the Minors on Monday.
