The Mets placed Semien on the 10-day injured list Thursday with a left hip flexor strain.

Semien played every inning of both legs of Wednesday's doubleheader but evidently picked up a hip injury in the process. It's not clear at this point how long the veteran infielder will be sidelined. Brett Baty will likely see the bulk of the reps at second base while Semien is out.

Arraez (foot) remains out of the lineup for Thursday's contest versus the Athletics.

Arraez will miss a second consecutive start after he had to depart Tuesday's game when he fouled a ball off the arch of his right foot. X-rays were clean, but Arraez remains sore. He's considered day-to-day. Casey Schmitt will cover second base again for the Giants in Thursday's series finale.

Koss (wrist) went 2-for-3 with an RBI in the ACL Giants' 9-1 win over the ACL Padres in the rookie-level Arizona Complex League on Wednesday.

After being optioned to Triple-A Sacramento on May 15, Koss fractured his left wrist and landed on the injured list. However, he began a rehab assignment in Arizona on Wednesday, logging two singles and an RBI over the first two innings before being lifted in the sixth. The 28-year-old infielder made San Francisco's Opening Day roster but slashed just .071/.133/.143 with a run scored in 15 plate appearances before being sent down.

Kiner-Falefa will undergo a CT scan Thursday on his injured left forearm to check for fractures, Tim Healey of The Boston Globe reports.

Kiner-Falefa was placed on the 10-day injured list this past weekend, but the Red Sox wanted to wait for the swelling in the infielder's arm to go down before sending him for testing. Once those results are in, the team will have a better idea as to how much time Kiner-Falefa might miss.

Massey is absent from the lineup for Thursday's game against the Rays.

The Rays have a right-handed opener (Casey Legumina) followed by a left-handed bulk reliever (Ian Seymour) going in the series finale, so the left-handed-swinging Massey will take a seat. Josh Rojas is at second base and will bat fifth for the Royals.

Seigler started at second base and went 2-for-4 with a double, an RBI and a run scored in Wednesday's 8-6 loss to Colorado.

Seigler made a fifth consecutive start at second base since being called up before being moved mid-game to third base for an injured Caleb Durbin (finger). The Red Sox confirmed Durbin's injury is not a fracture, per Owen Perkins of MLB.com, and it will be a matter of how much pain he can tolerate. If Durbin misses time, Seigler could take over at the hot corner while Andruw Monasterio fills in at the keystone.

Monasterio started at shortstop and went 1-for-4 with a solo home run in Wednesday's 8-6 loss to the Rockies.

Monasterio made a second consecutive start at shortstop with Marcelo Mayer (foot) opening the game on the bench. The homer was the third of the season for Monasterio, who entered Wednesday's contest batting just .087 (2-for-23) over his last 11 games. Mayer eventually entered the game for an injured Caleb Durbin (finger) and took over at shortstop while Monasterio covered second base.

Mayer (foot) replaced an injured Caleb Durbin (finger) in the third inning of Wednesday's 8-6 loss to the Rockies. The former went 1-for-2 with a run scored and a critical fielding error.

Mayer was held out of starting lineups Tuesday and Wednesday due to a sore left foot. However, the fact he was able to play defense for seven innings indicates the injury wasn't too serious.

Lopez started at second base and 1-for-1 before being lifted for a pinch hitter in Wednesday's 4-2 loss to the Marlins.

Lopez has been a frequent presence at second base and started every game there after the team optioned Josh Smith to Triple-A Round Rock. That opportunity could close as soon as Thursday, when shortstop Corey Seager (concussion) is expected rejoin the club. His return means Texas manager Skip Schumaker will need a home for Ezequiel Duran, who has served as the fill-in shortstop.

Castro went 3-for-5 with two runs scored and a stolen base Wednesday against the Red Sox.

Castro has swung the bat well for all of June, with this marking his sixth multi-hit effort in 18 starts. He's hit .324 with 14 RBI, 14 runs scored and two stolen bases in that span. Castro has established himself as a key part of Colorado's lineup, as he's served as the leadoff hitter against lefties across the last month, and he's primarily hit second against righties for the past two weeks.
