Baseball scores for Wednesday, August 21

Giolito gem sinks Twins

The Twins entered Wednesday with a three-game lead in the AL Central over Cleveland. One of the top reasons to believe the Twins will hold on and win the division is because they have the easiest remaining schedule in baseball. Yet on Wednesday the Twins lost their game and their series against the White Sox, thus reinforcing that anything can happen in this sport.

Blame it on Lucas Giolito, who recorded his third complete game and second shutout of the year. Giolito held the Twins to just three hits while fanning 12 batters.

In Giolito's last three starts, he's now fanned 36 batters in 21 innings, all the while allowing four earned runs, 11 hits, and four walks. That's what you call finishing strong, huh?

Castellanos cruising for the Cubs

Cubs right fielder Nicholas Castellanos went 4-for-5 with a two-run home run in Wednesday's 12-11 win over the Giants. Since joining the Cubs at the trade deadline, Castellanos has been on fire at the plate. He has eight home runs in the past 19 games.

His homer on Wednesday came in the first inning off Giants right-hander Dereck Rodriguez. It's the third consecutive first-inning homer for Castellanos, and he's the first player in Cubs history to do so. Castellanos credited his revitalization to being a part of team that's contending, he told MLB Network Radio on Wednesday.

Wednesday's win was the Cubs (68-58) fourth straight victory. Thanks to the Cardinals loss to the Brewers on Wednesday, Chicago is now in sole possession of first place in the NL Central.

Orioles tie record for most homers allowed

It's been a rough season for the Orioles. On Wednesday, it only got worse for Baltimore as they tied the record for most home runs allowed in a season. Royals second baseman Whit Merrifield's home run off Orioles' Aaron Brooks in the third inning was the 258th homer this season the O's have given up.

But, on the bright side, the Orioles won the series finale against Kansas City, 8-1. Ironically enough, Baltimore hit four home runs of their own. The homers came courtesy of Hanser Alberto, Anthony Santander, Renato Nunez and Jonathan Villar. 

Tigers notch improbable win over Astros

It was a wild one at Minute Maid Park on Wednesday. A couple of things: 1) Despite an outstanding outing from Justin Verlander, the Astros offense couldn't get enough runs on the board for the win, 2) The Astros were a heavy betting favorite (-600 at MGM Grand) and still lost and 3) The game closed out with a dramatic final out.

We cover that all right here.

Mets win fourth straight with a walk-off

The Mets keep finding ways to win. With Wednesday's 4-3 walk-off victory over the Indians, the Mets are now 26-10 since the second half began. Left fielder J.D. Davis had the game-winning hit off Indians reliever Brad Hand. It was a two-out RBI single, part of a two-run rally in the 10th inning. Take a look:

The Mets have won four straight games, and move a season-high six games over .500. They're now just a game and a half out from the final NL wild card spot. They seem to play their best in front of their home crowd in Queens. Wednesday was their 12th win in the past 13 at Citi Field. As they continue to try and make a push for the postseason, it helps that the Mets have more home games down the stretch than any team in the majors.

Indians right-hander Aaron Civale (1-2, 1.50 ERA) will face off against Mets right-hander Noah Syndergaard (8-6, 3.86) in Thursday's three-game series finale.

Padres lose but Mejia keeps hitting

The Padres may have lost their game (and series) with the Reds on Wednesday, but on the bright side, at least catcher Francisco Mejia continues to demonstrate his offensive prowess.

Mejia entered Wednesday with a 100 OPS+ on the year, and owes a fair amount of that figure to his red-hot August. In his first 15 games on the month, he hit .417/.451/.688 with three homers. On Wednesday, he launched his eighth dinger of the year:

The Padres have been rumored to have eyes on acquiring a better-hitting backstop. If Mejia keeps hitting like this -- or somewhat like this, even -- then they may not have to worry about it.

Highlight of the day: Rays win on walk-off wild pitch

The Rays may have blown a ninth-inning lead against the Mariners, but they earned the final laugh by winning when Matt Magill uncorked a wild pitch with the bases loaded in the bottom of the frame. Take a look:

You don't see that too often, but it is the second time this year the Rays have won this way:
