Busch went 1-for-3 with a solo home run and two total RBI in Wednesday's 4-1 win over the Blue Jays.

Busch got the scoring started with a home run against Toronto starter Kevin Gausman in the top of the third inning, his 23rd of the season, then chipped in a sac fly later in the game. The first baseman continues to mash against right-handed pitching with a .924 OPS and all but two of his long balls in those matchups. Busch's 23 home runs and 67 RBI are also both already career highs.

Lowe went 1-for-3 with two walks and a grand slam in Wednesday's 8-7 win over the Royals.

He got the fireworks started by hooking a Seth Lugo curveball over the fence in the right-field corner in the first inning. It was Lowe's first homer since July 19, ending a 20-game power drought, and his 16th of the season. The veteran first baseman still has some work to do to put his slump behind him, however -- in 23 contests since the All-Star break, he's batting only .160 (12-for-75) with three doubles, two long balls and seven RBI.

Rodriguez (elbow) underwent ulnar nerve transposition surgery Tuesday, Alex Stumpf of MLB.com reports.

Rodriguez is currently on the 60-day injured list and will not return this season, as he faces a multi-month rehab. Rodriguez last saw the field in early June but was injured while throwing a ball to second base in warmups between innings. He played in 18 games for the Pirates this season, slashing .173/.246/.250 with four doubles, two RBI, five runs scored and a 5:14 BB:K across 57 plate appearances.

The Brewers announced Tuesday that Hoskins (thumb) has progressed to on-field hitting and defensive work, MLB.com reports.

Hoskins remains on track to begin a rehab assignment in late August, just as the Brewers had anticipated when he was initially placed on the injured list July 7 due to a Grade 2 left thumb sprain. Since Hoskins landed on the shelf, Andrew Vaughn has posted a 1.055 OPS through his first 27 games with Milwaukee, and Vaughn's exceptional performance could put Hoskins on the outside looking in for an everyday role at first base when he returns from the 10-day injured list. The right-handed-hitting Hoskins should still have a clear path to playing time at either first base or designated hitter versus left-handed pitching once he's back to full health.

Contreras (foot) is not in the lineup for Wednesday's contest versus the Rockies.

Contreras was removed from Tuesday's game after being hit in the right foot by a pitch, so it's not a surprise he's sitting out Wednesday's matinee. The Cardinals are idle Thursday, and Contreras could be back in there for Friday's game against the Yankees. Alec Burleson is at first base for St. Louis on Wednesday.

Vaughn went 1-for-4 with a three-run homer in Tuesday's win over the Pirates.

Vaughn was the fourth Brewer to homer when he mashed a three-run homer 441 feet to left field in the sixth. He's hit safely in 16 of his last 17 games and now has 32 RBI since joining the Brewers on July 7, which is the second most in baseball since that date.

Steer went 1-for-3 with a double, a sacrifice fly and three RBI in Tuesday's 6-1 win over Philadelphia.

Steer delivered the winning hit with a two-run double in the fourth inning, before he knocked in the Reds' final run in the sixth inning. This was the fourth multi-RBI game over the last 12 contests for Steer, who's gone 11-for-44 with six extra-base hits and 16 RBI during that run.

Alonso went 3-for-5 with a double, two home runs, three RBI and three runs scored in Tuesday's 13-5 win over Atlanta.

It was a record-setting night for the All-Star first baseman, who passed Darryl Strawberry for the most home runs in Mets franchise history, per Anthony DiComo of MLB.com. After posting a miserable .548 OPS in the month of July, Alonso is heating back up in August. He's hitting .350 with six long balls, four doubles and 15 RBI across his first 40 at-bats of the month to bring his OPS to .880 for the season.

Contreras was removed from Tuesday's game against the Rockies with a right foot contusion, Derrick Goold of the St. Louis Post-Dispatch reports.

Contreras took a pitch off his foot in the fourth inning before being replaced on defense to start the sixth. The fact that the Cardinals are calling his injury a bruise suggests the 33-year-old didn't suffer any structural damage, though he may still sit out Wednesday's series finale as a precaution.

Mervis signed a minor-league contract with the Diamondbacks on Tuesday, Alex Weiner of ArizonaSports.com reports.

Mervis was released by the Marlins last Tuesday after slashing .250/.309/.625 through 149 plate appearances with their Triple-A affiliate in Jacksonville. The 27-year-old will now aim to get back to the majors with the Diamondbacks organization, but he may first need to find more success at Triple-A Reno before garnering consideration for a promotion.
