The Mariners designated Mastrobuoni for assignment Saturday.

After having his contract selected by Seattle on July 3, Mastrobuoni made only three at-bats for the big-league club before being DFA'd on Saturday. This marks the second time the 30-year-old has been designated for assignment by Seattle this campaign. With Julio Rodriguez coming back from the 7-day injured list, the Mariners needed to make room for him on the active roster.

Manager Pat Murphy said that Hamilton (hamstring) will begin a rehab assignment Tuesday, Todd Rosiak of the Milwaukee Journal Sentinel reports.

Hamilton landed on the injured list July 7 due to a strained left hamstring, and although he wasn't able to return immediately after the All-Star break, he doesn't appear to be too far away from activation. Joey Ortiz has filled in admirably as Hamilton's replacement at third base, posting a 1.054 OPS in Milwaukee's last eight games. The two players may split time at the hot corner more evenly once Hamilton is reinstated from the IL.

Karros isn't in the lineup for Saturday's game against the Reds.

Karros will retreat to the bench Saturday after going 0-for-4 with a run scored during a 7-2 loss in Friday's series opener. While Karros rests, Willi Castro will start at the hot corner and bat fifth.

Lewis isn't in the lineup for Saturday's game against the Cubs due to left hamstring soreness, Dan Hayes of The Athletic reports.

Manager Derek Shelton said Lewis has already begun to feel better since reporting to the ballpark Saturday, but the Twins will keep him on the bench as a precaution. His absence will put Josh Bell at first base, moving Ryan Jeffers to the DH spot and giving Victor Caratini a start at catcher.

Mead went 4-for-6 with three doubles, three RBI and four runs scored in Friday's win over the Athletics.

Mead is up to 16 doubles on the season, and he's been seeing the ball extremely well of late. He's hit safely in all but one of his last 10 games, posting six multi-hit performances and slashing .439/.500/.829 with a 1.329 OPS, three homers, five doubles, a triple, eight RBI, 10 runs scored and a stolen base over that stretch.

Muncy went 1-for-3 with a walk and a two-run home run in Friday's 2-1 win over the Yankees.

With the Dodgers down 1-0 in the top of the seventh inning, Muncy got hold of a Gerrit Cole slider and deposited it into the second deck in right field at Yankee Stadium for what proved to be the game-winning blast. It was Muncy's 18th homer of the season but his first in July, as he'd managed a weak .212/.297/.303 slash line with three RBI in his last 10 games before the All-Star break.

Garcia (hand) began swinging during the All-Star break and is set to be re-evaluated Sunday, per MLB.com.

Garcia landed on the injured list June 23 due to a nagging muscle strain in his left hand, but the 26-year-old took a step in the right direction by beginning to swing a bat during the All-Star break. Sunday's re-evaluation will determine whether he's ready to ramp up his hitting progression, including taking full rounds of batting practice, and should provide a clearer picture of when the third baseman could return to game action. Before being shelved, Garcia hit .261/.320/.373 with three homers, 30 RBI, 32 runs and five stolen bases across 69 games.

Riley went 2-for-5 with a solo home run and an additional run scored in Friday's 15-1 win over the Rangers.

Riley added to Atlanta's blowout victory with a solo homer in the eighth, his 10th long ball of the season. He's sitting at a .629 OPS over 390 plate appearances this season and has struck out 113 times, which is fifth-most in the National League. Perhaps Friday's performance is a sign of things to come for Riley for the second half of the regular season.

Caminero went 2-for-4 with a solo home run and an additional run scored during the Rays' 5-3 loss to the Red Sox in the second game of Friday's doubleheader.

Caminero was cleared to play in both of Friday's game after X-rays came back negative on his left hand, which was struck by a pitch during Tuesday's All-Star Game. He went 1-for-4 in the first game, which Tampa Bay lost 10-0, but he tied things up in the third inning of the second game with a solo homer off Eduardo Rivera. Caminero is up to 29 home runs and a .925 OPS which rank second and sixth, respectively, in the majors this season.

Chapman (abdomen) was cleared to begin a swinging progression Friday, Alex Pavlovic of NBC Sports Bay Area reports.

Chapman has been sidelined by an abdominal strain since the beginning of July. It's a good sign that he's begun taking swings, though the Giants have already ruled him out for the duration of their current road trip. The door remains open for him to return to the starting nine next Friday when the team returns home to face the Angels.
