Massey is absent from the lineup for Wednesday's contest versus the Rockies.

Massey has been one of the worst-hitting regulars in baseball this season and has been particularly brutal over the last two weeks, going 5-for-39 with a 10:1 K:BB across his last 41 plate appearances. Cavan Biggio is handling second base for the Royals on Wednesday.

Campbell is absent from the lineup for Wednesday's game against the Mariners, Chris Cotillo of MassLive.com reports.

It appears to be a routine day off for Campbell, who has now started 23 of Boston's first 26 games this season. The Red Sox are going with Romy Gonzalez at second base and in the No. 7 spot in the batting order Wednesday.

Amador will start at second base and bat eighth in Wednesday's game against the Royals.

After being called up from Triple-A Albuquerque on April 13 when Tyler Freeman (oblique) was placed on the injured list, Amador initially looked on track to fill Freeman's role as a backup infielder. However, with Ezequiel Tovar joining Freeman on the IL less than a week later, Amador has moved into a near-everyday role in the middle infield alongside Kyle Farmer. Amador will make his seventh start in nine games Wednesday, but he's thus far done little with his opportunity, going 2-for-20 with no walks and eight strikeouts.

Castro (oblique) remains out of the lineup for Wednesday's game against the White Sox.

Castro hasn't played in a week due to a right oblique injury, although indications are that he will not require a trip to the 10-day injured list. Luke Keaschall will start at second base and Brooks Lee will cover third base for the Twins.

Farmer is absent from the lineup for Wednesday's contest in Kansas City.

Farmer has essentially been an everyday player for the Rockies this season, but he's now been out of the lineup for two of the last three games, including two straight versus righties. Aaron Schunk will be at shortstop and Adael Amador will be at second base for Colorado.

Acuna is out of the lineup for Wednesday's game against the Phillies.

Acuna will take a seat after he had started at second base in each of the last four games while going 4-for-13 with two doubles, one walk and three runs scored. Brett Baty will get the nod at the keystone Wednesday, but both he and Acuna may see their opportunities trend downward once Jeff McNeil (oblique) makes his return from the injured list, likely this weekend.

Stott is out of the lineup for Wednesday's game against the Mets.

Stott will head to the bench along with fellow left-handed hitter Max Kepler while the Mets send lefty David Peterson to the hill. Edmundo Sosa will check in for Stott at second base.

Mets manager Carlos Mendoza said Wednesday that McNeil (oblique) is on track to be activated from the 10-day injured list prior to Friday's game versus the Nationals, Abbey Mastracco of the New York Daily News reports.

McNeil will play one final rehab game Wednesday before rejoining the Mets for their weekend series on the road against the Nationals. The 33-year-old is slashing .375/.444/.667 with two home runs and a 2:3 K:BB over 27 plate appearances in his first seven rehab games. McNeil is projected to be the Mets' primary second baseman but could also see some action in the outfield.

Cardinals manager Oliver Marmol said Tuesday that he plans to give Gorman a lengthy "run" of starts, Derrick Goold of the St. Louis Post-Dispatch reports.

Marmol revealed the plan prior to Gorman delivering a go-ahead, bases-clearing double in the eighth inning of Tuesday's win in Atlanta. Brendan Donovan (rib) being banged up has allowed Gorman to settle in at second base and in the third spot in the lineup for a second straight day Wednesday, and Gorman has started five straight contests overall. Donovan is not expected to need a stint on the injured list, and when he returns Gorman could get at-bats in the designated hitter spot at the expense of Alec Burleson.

Castro (oblique) took indoor batting practice prior to Tuesday's game against the White Sox, Bobby Nightengale of the Minneapolis Star-Tribune reports.

Castro admitted Tuesday that he doesn't feel 100 percent while he works through a right oblique injury, but he and Twins manager Rocco Baldelli are confident Castro can avoid a stint on the injured list. The oblique flares up when the switch hitter bats left-handed, so it's possible he returns only to hit right-handed initially.
