The postseason expansion that arrived in 2012 has brought added drama, added intrigue and, yes, added confusion to the final weeks of the season. With so many teams in the postseason race — sometimes on dual fronts (division and Wild Card) — the math can get a little messy.

The Astros’ season will not end on Sunday. They enter the final day one game behind the American League West-leading Rangers and one game ahead of the Angels in the race for the AL’s last available Wild Card spot.

The Pirates’ postseason plans are still on hold heading into Game 162. They know who they will play next week: the Cubs. They know when: Wednesday night at 8 ET (on TBS). But where? We’ll find out Sunday afternoon.

The Cubs continued to put pressure on the Pirates, winning their 96th game on Saturday night with a 1-0 decision over the Brewers.

Cole Hamels will be on the mound on Sunday when the Rangers face the Angels in their final attempt to clinch the American League West.

The Angels stunned the Rangers with five runs in the top of the ninth inning and rallied for an 11-10 victory on Saturday afternoon to keep their Wild Card playoff hopes alive. The Rangers need either a victory on Sunday to clinch the division title or a loss by the Astros on Sunday.

The Mets did not have their top lineup on the field for the second game of a doubleheader on Saturday night, but they still gave a dominant Max Scherzer his due after he no-hit them.

The players listed could provide difference-making stats for DraftKings participants on Sunday.

Tim Beckham hit a walk-off single with the bases loaded in the bottom of the ninth inning as the Rays stole a victory away from the Blue Jays with a 4-3 win on Saturday night at Tropicana Field. The loss dropped Toronto to one game behind Kansas City for the best record in the American League, with home-field advantage throughout the postseason on the line.

Reds manager Bryan Price will return to the club next season, general manager Walt Jocketty announced Saturday.

The Pirates announced the answer to one of the easiest questions in baseball: Gerrit Cole will start against the Cubs on Wednesday night in the National League Wild Card Game presented by Budweiser (8 p.m. ET on TBS).

The Twins were officially eliminated from postseason contention with a 5-1 loss to the Royals at Target Field. A Lorenzo Cain roller up the first-base line plated the go-ahead run in the seventh inning and prolonged an ugly frame that effectively ended Minnesota’s season.

The surprising Twins’ postseason hopes officially came to an end on Saturday in the penultimate game of the season, as their 5-1 loss to the Royals ended their late push for the second American League Wild Card spot.

When the Twins gave Torii Hunter a one-year contract last offseason, it seemed like the right fielder might have been coming back for one final curtain call.

Mets pitcher Steven Matz received an injection Friday to relax the muscles in his upper back, according to manager Terry Collins, with an eye toward throwing 90-100 pitches in an instructional league game Wednesday in Port St. Lucie, Fla.

Longtime Met and current team ambassador Rusty Staub suffered a heart attack en route from Ireland to New York City earlier this week, the Mets confirmed on Saturday. Staub’s plane was diverted back to Ireland, where Staub is now “resting comfortably in a hospital,” according to a team news release.

Gregory Polanco is getting pretty good at this 9-3 putout thing. For the second time in 17 games, the Pirates’ right fielder nailed a runner at first on a clean “hit.” This time, the play saved a run because it came with a runner on third and two outs in the second inning of Friday’s 6-4 win in 12 innings over the Reds at PNC Park.
