Kurtz went 6-for-6 with four home runs, a double, eight RBI and six runs in Friday's 15-3 win over the Astros.

In a dazzling performance, Kurtz become the 20th player in MLB history and the first rookie to hit four home runs in a single game. His first long ball came in the second inning, a two-run blast that padded the lead to 5-0. He added an RBI double in the fourth before turning up the power late with solo shots in the sixth and eighth frames. Kurtz capped the historic performance with a three-run blast off position player Cooper Hummel in the ninth. In addition to joining the four-homer club, Kurtz also accounted for 19 total bases, tying the all-time single-game mark Shawn Green established in his own four-homer performance for the Dodgers on May 23, 2002. Kurtz is on an incredible tear with nine home runs in his current 12-game hitting streak, during which he has hit .553 (26-for-47) with 20 RBI.

Naylor is starting at first base and batting out of the cleanup spot against the Angels on Friday.

Naylor will make his Mariners debut one day after being traded by the Diamondbacks. The 28-year-old slugger, who has an .807 OPS with 11 steals, 11 home runs and 59 RBI this across 392 plate appearances this season, is expected to take over as the everyday starter at first base.

The Astros claimed Davidson off waivers Friday.

The Athletics designated Davidson for assignment Wednesday, and he'll get a fresh start within the Astros' organization. The 27-year-old went 3-for-20 with the Athletics in 2025, but he slashed .266/.414/.402 in 326 plate appearances at Triple-A Las Vegas.

Guerrero went 3-for-5 with a double, two runs scored and two RBI in Thursday's win over the Tigers.

The Blue Jays' $500 million man led the way in an 11-run, 15-hit barrage. It was Guerrero's third straight multi-hit performance, and over the last 15 contests he's slashing .375/.478/.500 with eight RBI and 12 runs. Despite that impressive stretch, he's still looking for his power stroke -- with 13 homers through 101 games, Guerrero's on pace to fall short of 25 over a full season for the first time.

Contreras went 2-for-3 with a walk, a double, a home run and four RBI in Thursday's 9-7 win against San Diego.

The first baseman put St. Louis on the board with an RBI double in the opening frame and followed up with a three-run homer in the second inning. Contreras has a modest four-game hit streak with an extra-base hit in each of those contests, going 9-for-21 with four doubles and two home runs. The strong performance coming out of the All-Star break has boosted his season slash line to .262/.345/.452 through 98 games.

The Diamondbacks recalled English from Triple-A Reno on Thursday, Aaron Hughes of SI.com reports.

With Josh Naylor shipped to Seattle in a trade Thursday, Arizona is bringing English back up to fill the void at first base. Pavin Smith (oblique) is still on the 10-day injured list, so English should get plenty of opportunities while Smith is idle. English made his MLB debut earlier in July, going 0-for-4 with one RBI and a pair of strikeouts in one game before being sent back down. He's slashed .341/.390/.566 with 11 home runs, 65 RBI and 44 runs scored at Triple-A this year.

Torkelson went 1-for-4 with a solo home run in Thursday's 11-4 loss to the Blue Jays.

Torkelson was having a forgettable game until the bottom of the ninth inning, when he launched his 22nd home run of the season. It's his first long ball in seven games following the All-Star break, but the 25-year-old has been known to go on power surges throughout his career and could be primed for a hot stretch soon. Torkelson's career high of 31 home runs, which he recorded two years ago, could be within reach if he heats up down the stretch.

The Diamondbacks traded Naylor to the Mariners on Thursday in exchange for Brandyn Garcia and Ashton Izzi, Jeff Passan of ESPN.com reports.

The Diamondbacks are expected to unload a number of assets before the trade deadline, and they'll officially kick things off by sending Naylor up to Seattle. Eugenio Suarez has been the primary target for many teams looking to add a bat for a postseason run, but Naylor has fared well in his own right, slashing .292/.360/.447 with 11 homers, 59 RBI, 49 runs scored and 11 stolen bases over 93 games in Arizona. Now with the Mariners, the 28-year-old slugger will presumably start every day at first base, taking playing time away from Luke Raley and Donovan Solano.

Freeman went 2-for-5 with a run, a stolen base and two RBI in Wednesday's 4-3 win against Minnesota.

Freeman capped a ninth-inning comeback with a two-out, two-run, walk-off single that just evaded the reach of a diving Harrison Bader. The knock was Freeman's second hit of the game, marking just his second multi-hit appearance over his past 15 contests. The All-Star first baseman is batting an uncharacteristically poor .204 during that stretch, though he's still at a .295 batting average on the campaign, the third-best figure among qualified National League hitters.

Horwitz went 1-for-4 with a grand slam Wednesday against the Tigers.

Horwitz has struggled for most of July, but he is turning things around since the All-Star break. He has hits in each of his last four games, including a pair of doubles and a home run. Horwitz also looks to be the Pirates' primary leadoff hitter, at least against right-handed pitching, after briefly ceding the role to Tommy Pham.
