Murakami has been diagnosed with a Grade 2 right hamstring strain and is expected to miss 4-to-6 weeks, James Fegan of SoxMachine.com reports.

Murakami suffered the injury while running to first base after hitting a grounder Friday versus Detroit. The star rookie landed on the 10-day IL earlier Saturday, and he will miss far more than the minimum. While Murakami is sidelined, Miguel Vargas is expected to move from the hot corner to make most of the team's starts at first base, and Colson Montgomery is shifting from shortstop to third base for Saturday's contest.

The Mets selected Perez's contract from Triple-A Syracuse on Saturday.

Perez joined the Mets on a minor-league deal May 6 and has since given up two earned runs in seven innings at Syracuse while striking out 10 batters and walking five. He'll now return to the majors to replace Tobias Myers in the Mets' bullpen and likely work in low-leverage situations to begin with. Anderson Severino was designated for assignment to make room for Perez on the 40-man roster.

The Mets optioned Myers to Triple-A Syracuse on Saturday.

Myers has struggled on the mound since the start of May, posting a 6.43 ERA and 1.50 WHIP with a 10:4 K:BB over 14 innings this month. He'll head back to Triple-A to right the ship, and the Mets will replace him by selecting Cionel Perez's contract from Syracuse.

Walls (hamstring) is starting at shortstop and batting ninth for the Rays on Saturday, Marc Topkin of the Tampa Bay Times reports.

Walls missed each of Tampa Bay's past three games due to a hamstring issue, but he's feeling well enough to return to action Saturday. Three different players started at shortstop for the Rays while Walls was sidelined, and Ben Williamson -- who played the position Friday -- is sliding over to second base for Saturday's matchup.

Carter isn't in the Rangers' starting lineup for Saturday's matchup against Kansas City.

Carter frequently sits against lefty starters, but this time he's being held out of the lineup versus right-hander Seth Lugo. Michael Helman will man center field for Texas in Carter's stead. Carter was hit by a pitch Friday, but it's unclear if that has anything to do with him being held out Saturday, per Matthew Postins of SI.com.

The Rays optioned Bigge to Triple-A Durham on Saturday.

The 27-year-old will end up as the roster casualty necessary to make room in the bullpen for Cole Sulser (back), who returned from the injured list Saturday. Bigge owns a 6.98 ERA and 1.45 WHIP through 19.1 innings with the Rays this season and gave up three earned runs without recording an out during his last appearance Friday.

The Rays reinstated Sulser (back) from the injured list Saturday.

Sulser didn't play in any rehab games while recovering from a lower-back strain, but he has been facing live hitters over the past few days and will now rejoin the Rays' bullpen following a minimum-length IL stay. The 36-year-old righty will presumably reclaim a setup role after posting a 3.68 ERA and 1.36 WHIP through 22 innings on the year. Hunter Bigge was optioned to Triple-A in a corresponding move.

The White Sox transferred Leasure (forearm) to the 60-day injured list Saturday.

Leasure landed on the injured list Friday with a right flexor strain and will be shut down from throwing for four weeks. He isn't expected to be activated until the second half of the season, so the White Sox will stash him away on the 60-day IL and give his 40-man spot to Jacob Gonzalez, who joined the big club Saturday.

Ruiz went 2-for-4 with a solo home run in Friday's loss to the Padres.

The backstop took Lucas Giolito deep in the second inning as the Nationals grabbed an early lead the bullpen let slip away. Over 15 games in May, Ruiz is slashing .364/.368/.727 with four of his five homers on the season along with eight doubles, 10 runs and 16 RBI.

The White Sox selected Gonzalez's contract from Triple-A Charlotte on Saturday.

Gonzalez will provide the White Sox with extra infield depth and a power bat to help make up for the loss of Munetaka Murakami, who landed on the injured list Saturday with a hamstring strain. Gonzalez has experience fielding all four infield positions -- primarily second base and shortstop -- which could help him crack the starting nine somewhat regularly while he's in the big leagues. Jordan Leasure (forearm) was transferred to the 60-day IL in a corresponding move.
