By the standards of lame-wad Mondays, it's pretty hefty slate -- 11 games under the lights. The headliner? That depends upon your rooting interests, of course, but the ALCS rematch in Houston was pretty intriguing. Here is everything you need to know about Monday's MLB action:

Monday's scores

Pollock homers three times against Dodgers

The Dodgers were dealt a devastating blow Monday afternoon, when it was announced Corey Seager would miss the remainder of the season with Tommy John surgery. He had been dealing with elbow issues since last season. The Dodgers were already without Justin Turner (wrist) and Yasiel Puig (hip). Now Seager is hurt as well.

Because the Seager injury wasn't bad enough, the Dodgers also lost Monday night's series opener to the D-Backs, the team they're chasing in the NL West. And, to really rub it in, A.J. Pollock clubbed three home runs against three different pitchers (Ross Stripling, Brock Stewart, Josh Fields) in his team's victory.

Pollock is the fourth player to hit three home runs in a game this season, joining Mookie Betts, Christian Villanueva, and Matt Davidson.

Monday's result improves the D-Backs to 20-8 and drops the Dodgers to 12-16. The Dodgers have dropped six of their past seven games, with five of those six losses coming against the Marlins and Giants. Ouch.

The season is young, sure, but an eight-game deficit? That's rough. Los Angeles has already exhausted their margin for error, and now they won't have Seager for the rest of the season. There is lots of season to go. Lots. It sure feels like things are starting to get away from the Dodgers a little bit, though.

Hader continues incredible season

The best reliever in baseball? It very well might be Brewers southpaw Josh Hader right now. Monday night Hader picked up his fourth save since Corey Knebel landed on the disabled list, and it was an old-school eight-out save. All eight outs were strikeouts.

Hader has now struck out 39 batters in 18 innings so far this season. Or, to put it a better way, he has struck out 39 of 62 batters faced, or 62.9 percent. That is absurd. A great strikeout rate is around 40 percent. Thirty-nine strikeouts against five hits and four walks in 18 innings is video game stuff.

Red Sox tie April grand slam record

Another day, another grand slam for the Red Sox. They've been hitting them with regularity so far this season. Xander Bogaerts did the honors Monday night. To the action footage:

That is grand slam No. 6 for the Red Sox already this season. They didn't hit a single grand slam last season. Not one. The six grand slams are tied for the most in April in baseball history.

Always a good day when you can sneak an Expos reference into a stat.

Astros win ALCS rematch

Last October, the Astros -- as a taut prelude to their seven-game World Series triumph over the Dodgers -- barged back from down 3-2 to nip the Yankees in a seven-game ALCS. On Monday in Houston, those same two squadrons got together for the first time in 2018, and best of all it's a four-game set. 

The Yankees went into the series at 18-9 and having won nine straight. The Astros, meanwhile, were 19-10 with an MLB-best plus-66 run differential. In addition to the general strength of each team, this one's also a tantalizing clash of strengths: The Yankees come in leading the AL in runs scored, home runs, and OPS; while the Astros are the AL leaders in ERA and strikeouts. 

Pitching prevailed Monday night. Charlie Morton took a no-hitter into the sixth inning and held the high-powered Yankees to one run in 7 2/3 innings before giving way to the bullpen. He struck out 10.

Double-digit strikeout performances have become the norm for the Astros so far this season. Monday's game was their ninth double-digit strikeout game. No other team has more than five.

New York's winning streak ends at nine. That's the bad news for the Yankees. The good news is Sonny Gray pitched well for the first time pretty much all season. Gray went into Monday's start with a 7.71 ERA and a 2.14 WHIP in four starts and 21 innings. He was able to hold the Astros to two runs in six innings in Houston.

Gray's not out of the woods yet. One good start is an encouraging first step and nothing more. It is something he can build on though. Something positive he and the Yankees can take away from the end of their losing streak.

Twins continue to skid

Boy, things are not going well for the Twins right now. They lost again Monday, this time to the Blue Jays, and they have lost 10 of their past 11 games. They've been outscored 90-44 in those 11 games. Good gravy.

Free-agent pickup Lance Lynn got the start Monday night and again, it did not go well. He got hit around again.

Lynn is now sitting on an 8.87 ERA, and he has allowed at least five runs in four of his five starts. He has also walked 23 batters in 23 2/3 innings. Things couldn't be going much worse for Minnesota right now.
