Porter cleared waivers and was outrighted to Triple-A Syracuse by the Mets on Friday.

Porter joined New York on a major-league contract in mid-July and was designated for assignment Tuesday without appearing in a game. The 29-year-old has also spent time in the Giants and Royals organizations this season, and he has a combined .858 OPS in 57 games at the Triple-A level.

The Mets optioned Megill to Triple-A Syracuse on Friday, Mike Puma of the New York Post reports.

He's clearing out to make room on the roster for trade-deadline acquisition Paul Blackburn, who has officially been added to the roster. Megill will join the rotation at Syracuse to stay stretched out in case he's needed for a start in the majors during the final two months.

Arcia went 1-for-3 with a solo home run in Thursday's win over the Marlins.

He connected on Atlanta's third long ball of the game, launching a Max Meyer fastball over the left-field fence in the third inning. Arcia has hit safely in 12 straight games, a stretch in which the veteran shortstop is slashing .350/.409/.600 with three homers, four runs and six RBI. Thursday's blast was his 10th of the year, the fourth time in his career he's reached double digits in a season.

O'Brien (forearm) could be activated from the 60-day injured list next week after making two more rehab appearances with Triple-A Memphis, John Denton of MLB.com reports.

O'Brien will make back-to-back appearances with Memphis on Saturday and Sunday, which would appear to be the final box he'll need to check before rejoining the Cardinals' bullpen. The reliever has been sidelined since suffering a right flexor strain back on Opening Day.

Riley went 1-for-4 with a solo home run in Thursday's win over the Marlins.

The third baseman got Atlanta on the board by taking Max Meyer deep in the first inning. Riley is coming off a strong July that saw him slash .280/.324/.527 with five homers and 14 RBI in 24 games, but with only 15 long balls on the year, he'll need to stay hot down the stretch to reach 30 for a fourth straight season.

The Giants selected Encarnacion's contract from Triple-A Sacramento on Friday.

The 26-year-old signed a minor-league contract with the Giants in May after beginning the year in the Mexican League, and he'll receive a look in the big leagues after he posted a .352/.438/.616 slash line with 10 homers in 33 games for Triple-A Sacramento. Encarnacion isn't likely to have a regular spot in the lineup, but he could see some playing time against left-handed pitchers.

The Giants activated Hjelle from the bereavement list Friday, Alex Pavlovic of NBC Sports Bay Area reports.

Hjelle had been away from the club since Sunday. He will return to a middle relief role.

Nootbaar went 1-for-4 with a stolen base in Thursday's 5-4 loss to the Cubs.

Nootbaar has gone 10-for-38 (.263) over 13 games since the All-Star break, adding a 6:10 BB:K and three extra-base hits in that span. The outfielder has operated as the Cardinals' primary right fielder, but the addition of Tommy Pham, a right-handed hitter, at the trade deadline appears to be a threat to Nootbaar's spot in the lineup versus southpaws. For the year, Nootbaar is slashing .236/.326/.394 with seven home runs, five steals, 22 RBI and 20 runs scored over 59 contests.

The Giants designated Hill for assignment Friday, Alex Pavlovic of NBC Sports Bay Area reports.

The transaction frees up a spot on the 40-man roster for the addition of Jerar Encarnacion. Hill went 3-for-12 at the plate during his week with the big club.

Padres manager Mike Shildt said Friday that King won't make his scheduled start Sunday against the Rockies due to a lingering left calf soreness after being hit by a comebacker in his last start this past Saturday in Baltimore, Sammy Levitt of 97.3 The Fan reports.

Shildt suggested that King just needs a couple extra days of rest and will be ready to take the hill early next week, but the Padres are still discussing their options to fill in for him Sunday. Carl Edwards has been stretched out as a starter at Triple-A El Paso since he signed a minor-league deal last month and last pitched Sunday, so he could be a possibility for a spot start. Edwards would need to be added to the 40-man roster, however.
