New York Mets first baseman Pete Alonso hit his 27th home run of the season Sunday to set the franchise rookie record.

Alonso's homer in the top of the fourth inning off the Chicago Cubs' Cole Hamels traveled 454 feet to center at Wrigley Field. The home run is tied for his second-longest this season.

Darryl Strawberry had held the Mets' record for home runs by a rookie since he hit 26 in 1983.

The last time the Angels' Albert Pujols homered at Busch Stadium, it was a championship season. 

Pujols, 39, homered in the seventh inning off Cardinals starter Dakota Hudson, setting off another celebration in a weekend that's been full of them.

"Trying to walk around the bases and get to the plate, and trying to get in the dugout and hold everything in," Pujols said. "Man, that was hard.

"It's gonna be up there for me -- for my career, for my family, my wife, Deidre, and my five kids and my friends and family that are here in town. It's just a moment that I will treasure forever."

Rookie slugger Pete Alonso said he began the season not thinking about hitting homers or setting milestones.

Alonso hit his 26th homer to set the NL rookie record for most homers before the All-Star Game as the New York Mets routed the Chicago Cubs 10-2 on Saturday.

Eighteen years after the Twins took Joe Mauer with the first overall draft pick, the hometown star with the textbook left-handed swing was still having a hard time realizing his place among the franchise's all-time greats.

As Mauer's jersey number formally joined the seven others retired by the Twins on Saturday night, the six-time All-Star and three-time batting champion sounded as awestruck of his place in team history as on his first day of rookie ball.

"Wearing the No. 7 the past 15 years has been my absolute pleasure," Mauer said, his voice cracking as he paused to compose himself, "and being able to play my entire career in that number in front of my family, friends and fans here at home means more to me than any of you will ever know."

Edwin Encarnacion paused at the plate and watched while his 400th homer flew toward the Mariners' bullpen beyond left field. He pumped his fists as he circled the bases while his teammates went wild for the milestone.

Encarnacion hit two homers to become the third active player with 400 homers, and Tom Murphy had two more homers in the Mariners' 9-3 victory over the Angels on Sunday.

Houston Astros prospect Yordan Alvarez, the minor league home run leader, homered in the second at-bat of his major league debut on Sunday against the Baltimore Orioles.

"That's an incredible performance for him when all everybody ever wanted today was a homer from him,'' manager AJ Hinch said. "That's what everybody expected, and he did it.''

Adrian Beltre got one more tap on the top of the head from Elvis Andrus, and a visit by the person who brought the four-time All-Star third baseman up to the major leagues as a teenager.

The Rangers retired Beltre's No. 29 jersey on Saturday night after he spent the last eight of his 21 major league seasons in Texas.

Josh Bell finished off his historic May with two more hits, giving him 94 total bases in May, the most by any player in May since Willie Mays (102) in 1958.

Bell went 2-for-5 and drove in a run to help the Pittsburgh Pirates pounce on struggling Milwaukee starter Jhoulys Chacin in a 9-4 victory Friday night.

His 94 total bases in May is the most by any player in any month in the Pirates' 138-year history.
