Bryce Harper set a franchise record Tuesday with his 124th walk of the season, breaking a mark set in 1973 by Ken Singleton.

Harper also has set career highs in his fourth season with 41 home runs and 117 runs scored.

Singleton set the mark in his third MLB season with the Montreal Expos, a season in which he played in all 162 games.

Dallas Keuchel allowed just one run in 7 2/3 innings against the Los Angeles Angels at Minute Maid Park on Monday night, improving his home record to 14-0 with a 1.47 ERA.

No pitcher has gone undefeated at home with at least 14 victories, according to the Baseball-Reference Play Index, which goes back to 1914.

Ron Darling of the New York Mets is the most recent pitcher to go 14-1 at home.

Keuchel's next start comes on Sunday at home against the Texas Rangers.

Mike Trout hit a grand slam and a solo home run on Thursday against the Minnesota Twins, giving him a career-high 38 home runs this season.

It marked the eighth multihomer game of his career.

Trout hit 36 homers last season and boasts the fourth-highest career home run total (136) of any player through his age-23 season, behind Eddie Mathews, Mel Ott and Alex Rodriguez.

Kansas City Royals pitching coach Dave Eiland has concluded that Johnny Cueto's struggles can, at least in part, be attributed to his delivery.

Eiland, who held a video meeting with Cueto before his start against the Baltimore Orioles on Sunday night, "concluded that he was flying open -- his left shoulder turning too soon in his delivery -- and that was causing his pitches to flatten out, especially his cutter," writes Dave Schoenfield.

Despite the recent session, Cueto allowed four home runs to Baltimore, increasing concern as Kansas City prepares for the playoffs. The right-hander has been a disaster on the mound since firing a shutout in his home debut.

Cueto has a 9.57 ERA over his last five outings.

Bartolo Colon extended his scoreless streak to 31 innings before allowing a few runs against the Atlanta Braves on Thursday night.

The New York Mets right-hander set the record for the longest single-season scoreless streak by a pitcher age 42 or older, according to the Elias Sports Bureau. Hall of Famers Warren Spahn and Cy Young previously held the record.

Colon came within 1⅔ innings of the franchise record, set by R.A. Dickey in 2012.

The Tampa Bay Rays decided their hitters were taking too many pitches, so they instructed them to become more aggressive in August with impressive results.

Tampa Bay averaged 3.74 pitches per plate appearance, its lowest monthly mark of the season, and produced a .781 OPS, fifth highest in the majors in the month.

The trend has continued in six September games — the Rays are averaging 3.67 pitches per plate appearance, and their .841 OPS is ninth in the majors.

"Let's get 'em early (in counts)," Kevin Cash said. "(Pitchers) have such good stuff, they're so powerful, why would you even want to hit with two strikes anymore?"

The manager continued, "We're not looking to walk. We want guys to put themselves in position to impact the ball, hit it hard. More times than not, that comes in hitter-advantage counts:€“ 1-0, 2-0. We figured out that to get in those counts, you have to be aggressive (early) and get pitchers out of the zone."

Alex Rodriguez has reached 30 home runs for the 15th season, tying Hank Aaron's Major League record.

Rodriguez hit his 684th career home run leading off the sixth inning Tuesday night against the Baltimore Orioles.

The 40-year-old hadn't hit the 30-homer mark since 2010.

In just over one month, Yoenis Cespedes has done some pretty special things with the New York Mets.

Since coming over in a trade from the Detroit Tigers, Cespedes is hitting .311 with 13 home runs and 34 RBIs in 34 games.

He has registered three games with three extra-base hits since joining the Mets. Only four players in franchise history have had three such games over the course of a full season -- Darryl Strawberry (1987), Carlos Beltran (2006), David Wright (2008) and Lucas Duda (2015).

“I don't really know what [the front office is] thinking. My plan is to go out there and have fun," Cespedes, who will be a free agent this winter, said on Monday. "I enjoy the team. It's a really great team. I love the city of New York. I love the fans. What we've got going here is a really good thing. So I don't really think about that. I just want to go out and do my job and produce and put up great numbers."

Ryan Braun became the 31st player in Major League history to post at least four seasons of 20 home runs and 20 stolen bases when he stole second base on Thursday.

"I've been incredibly unlucky all year. With any luck, I'd be a lot closer to 30/30," Braun said. "But I just keep going. The stolen bases that come in one-run games, in big situations, feel like they're more meaningful during the course of the game. But like I've said many times, I try not to reflect on any statistical accomplishments during the year unless I have to."

Braun also posted 20/20 seasons in '09 (32 home runs/20 stolen bases), '11 (33/33) and '12 (41/30).

Bryce Harper scored four runs for the Washington Nationals on Thursday without recording an official at-bat.

Harper saw 20 pitches and didn't swing once, drawing four walks. He became the second player in the Major Leagues this season to have multiple games with at least four walks, joining Paul Goldschmidt.

The Elias Sports Bureau notes Harper is the first player to have two career games with four walks before age 23 since Hall of Famer Joe Morgan in 1966.
