Luzardo (back) won't start Saturday's game against the Mariners, Daniel Alvarez-Montes of ElExtraBase.com reports.

Luzardo experienced back tightness in his last start and was pulled after 77 pitches and showed decreased velocity. While the Marlins initially listed Luzardo as their probable pitcher Saturday, they'll refrain from putting the 26-year-old lefty on the mound against Seattle and give him some extra rest. For now, Luzardo is scheduled to make his next start during a four-game series at Philadelphia next week.

The Cardinals optioned Kloffenstein to Triple-A Memphis on Friday.

Kloffenstein turned in a 1-2-3 inning in his major-league debut Thursday versus the Giants to help out a depleted Cardinals bullpen but will quickly head back to Memphis. The big righty will re-enter Memphis' starting rotation, where he's collected a 3.97 ERA and 1.13 WHIP through 77 innings across 14 starts.

Peterson will no longer start Sunday versus the Cubs after being pushed back in the Mets' rotation, Tim Healey of Newsday reports.

It's not clear when Peterson's next start will come, but it now figures to be early next week against the Yankees. Luis Severino has been bumped up to start Sunday in Chicago on regular rest.

Severino will move up in the Mets' rotation to start Sunday against the Cubs, Tim Healey of Newsday reports.

Severino had been slated to start Tuesday versus his former club, the Yankees, but will be bumped up a couple days to take the ball on regular rest. David Peterson had been on turn for Sunday but now figures to take the ball next week against the Yankees.

Mazur did not factor into the decision in a win over the Brewers on Thursday, allowing three runs on five hits and three walks over 4.2 innings. He struck out three.

Mazur allowed one run in the first inning after surrendering a leadoff double to Brice Turang to open the contest, but the right-hander was able to keep the Brewers' offense at bay over the next three frames as San Diego took a 4-1 lead. The 23-year-old's luck would run out in the fifth, however, when Willy Adames chased him from the game with a two-run shot. Mazur has now failed to make it through five innings in each of his last three starts, allowing 13 runs over that stretch while posting a putrid 9:12 K:BB. He's likely to be pushed out of the rotation as soon as Yu Darvish (groin) returns.

Winn (3-8) took the loss against the Cardinals on Thursday, allowing five runs on five hits and one walk over 2.2 innings while striking out two.

Winn ran into trouble immediately, allowing a walk and a hit in the first two at-bats before going on to surrender three runs in the opening frame. He would go 1-2-3 through the second inning but once again failed to retire the first two batters to begin the third, leading to another two runs coming home for St. Louis. The right-hander has now surrendered five or more runs in five of his last six starts and has lost his last five decisions (spanning six starts). He currently holds a 10.38 ERA this month (three starts) after posting an 18.36 ERA through three starts in May.

Blach (3-5) allowed five runs on 10 hits and one walk while striking out two batters over four innings in a loss to the Dodgers on Thursday.

Blach was hit hard in the start -- five of the 10 hits he allowed, including three homers, went for extra bases. It was the first time this season he's served up three homers in an outing, and the five runs he allowed were the second-most he's surrendered in a start this season. Blach is off the fantasy radar given his home park and the fact that he's compiled a 5.13 ERA, 1.51 WHIP and 29:10 K:BB over 54.1 innings this season.

Stone (8-2) earned the win over Colorado on Thursday, allowing two runs on four hits and two walks while striking out seven batters over 5.1 innings.

Stone performed well in the Colorado altitude, as none of the four hits against him went for extra bases. The right-hander was working on a shutout through five frames but fell off in the sixth inning, loading the bases with one out on a pair of walks and a single before getting the hook. Two of those three runners scored after his departure, but that didn't prevent Stone from registering the win. The 25-year-old has become a key part of Los Angeles' rotation in his first full MLB campaign, leading the team with eight victories while posting a 3.04 ERA, 1.20 WHIP and 63:25 K:BB over 80 innings.

Gasser will have surgery Monday to repair UCL damage in his left elbow, Todd Rosiak of the Milwaukee Journal Sentinel reports.

It's unclear whether Gasser is undergoing Tommy John surgery or the internal brace procedure, but he will be out for at least the next 12 months. It's tough timing for the promising young pitcher, as he had pitched well across his first five big-league starts, maintaining a 2.57 ERA and 1.04 WHIP in 28 innings.

Gore (6-6) suffered the loss Thursday, allowing four runs on 10 hits and two walks in five innings against the Diamondbacks. He struck out seven.

Gore was unable to match his opponent's efficiency on the mound, allowing 12 baserunners and needing 103 pitches to complete five frames. The Diamondbacks meanwhile needed only 87 pitches for the entirety of the contest including just 70 in seven innings by starter Ryne Nelson. Gore was done in by a lot of dink and dunk, as nine of the 10 hits he allowed were singles. It was just the second time all season Gore has allowed more than three runs and the fifth time he's eclipsed the 100-pitch plateau. The performance raised Gore's ERA from 3.24 to 3.49, while his WHIP lifted from 1.32 to 1.39. His next opportunity to toe the rubber is set for early next week when the Nationals travel to San Diego to take on the Padres.
