Peterson (9-3) took the loss Friday against Philadelphia, allowing five runs (four earned) on eight hits and no walks over 3.2 innings. He struck out four.

EDGE Analysis

The New York southpaw failed to reach the fifth inning for the first time this season, as he allowed a run in every frame during this 64-pitch performance. This is now the second time in three starts Peterson has yielded four earned runs after previously stringing together seven consecutive outings allowing two or fewer runs. The 29-year-old's ERA rose from 2.85 to 3.08 across 114 total innings to go with a 1.33 WHIP and 93:43 K:BB. Peterson looks to bounce back in his next start, currently scheduled to be one with tremendous playoff implications at Atlanta next week.

Peterson didn't factor into the decision Sunday against Philadelphia, allowing one run on four hits and a walk across 7.2 innings. He struck out six.

EDGE Analysis

Peterson and Cristopher Sanchez were locked into a pitchers' duel Sunday, but neither were credited with the victory. Peterson yielded five runs (four earned) in his previous start after yielding two or fewer earned runs in seven consecutive outings. Since the start of August, Peterson is 4-1 with a 2.22 ERA and a 46:17 K:BB across 56.2 innings.

Peterson (9-2) took the loss Tuesday, giving up five runs (four earned) on eight hits and two walks over 4.1 innings as the Mets were downed 6-2 by the Blue Jays. He struck out two.

EDGE Analysis

The southpaw was saddled with his first loss since July 28 as he struggled with his command. While Peterson tossed a respectable 51 of 76 pitches for strikes, he uncorked two wild pitches and plunked a batter, and he gave up some hard contact when he was in the strike zone. He saw his quality start streak end at five, and since the beginning of August he still sports a 2.39 ERA, 1.22 WHIP and 40:16 K:BB through 49 innings, Peterson will look to bounce back in his next outing, which lines up to come at home early next week against the Nationals.

Peterson (9-1) picked up the win Tuesday, allowing one run on six hits and a walk over six innings in a 7-2 victory over the Red Sox. He struck out 11.

EDGE Analysis

The 11 strikeouts were a career high for the southpaw, who generated an impressive 20 swinging strikes among his 89 pitches. Peterson has won four straight decisions and has six quality starts in seven trips to the mound since the beginning of August, posting a 1.81 ERA, 1.12 WHIP and 38:14 K:BB through 44.2 innings over that stretch. He'll look to keep rolling in his next outing, which is scheduled to come on the road early next week in Toronto.

Peterson didn't factor into the decision Thursday against Arizona, allowing two runs on seven hits and two walks over seven innings. He struck out four.

EDGE Analysis

Peterson has now gone seven innings in three straight starts while delivering quality starts in five of his last six outings -- he's pitched to an impressive 1.86 ERA in that span (38.2 innings). Overall, the left-hander is 8-1 with a 2.83 ERA, 1.32 WHIP and 70:39 K:BB across 92.1 innings this season. Peterson will look to keep rolling in his next start, currently scheduled for next week at home versus the Red Sox.

Peterson (8-1) picked up the win over the Padres on Saturday, allowing one run on five hits and two walks over 7.1 innings while striking out two.

EDGE Analysis

Peterson surrendered just one hit through the first four innings before allowing three of the first four batters to reach in the fifth, leading to one run coming home for San Diego. He was later relieved by Dedniel Nunez with one out in the seventh, marking the second consecutive start in which he's been able to get through at least seven innings. Peterson has also logged quality starts in three straight and in four of his five outings this month. On the downside, his two strikeouts Saturday marked his lowest total in that category since July 1 against the Nationals and he's now issued multiple walks in seven of his last nine starts.

Peterson didn't factor into the decision Monday against Baltimore, allowing three runs (two earned) on six hits and a walk across seven innings. He struck out eight.

EDGE Analysis

Peterson logged his third quality start in four appearances and kept the Orioles off the scoreboard until the fifth inning Monday. The left-hander tied his season high in strikeouts and issued fewer than three walks for the second time in seven starts. Peterson has been excellent in August, boasting a 1.85 ERA across 24.1 innings. He's on track to cap off a two-start week Saturday at San Diego.

Peterson (7-1) allowed an unearned run on three hits and four walks while striking out four over 6.1 innings to earn the win Wednesday over the Athletics.

EDGE Analysis

This was the sixth time Peterson has gone at least six innings, and it was one of his strongest outings this year. The one concern that remains is his high walk rate -- he's issued at least three walks in five of his last six starts and has a 4.3 BB/9 this season. Peterson has managed to post a 3.04 ERA despite a 1.39 WHIP and 56:34 K:BB through 71 innings over 13 starts on the year. He's projected for a tougher home start versus the Orioles early next week.

Peterson (6-1) earned the win Thursday, allowing one run on four hits and three walks over five innings against the Rockies. He struck out five.

EDGE Analysis

Peterson was provided a four-run lead prior to taking the hill and saw the lead grow as high as seven as he cruised to his sixth win. A Brenton Doyle sacrifice fly was the only run tallied against the Denver-born Peterson, who has now allowed two runs or fewer in eight of his last nine starts. While his WHIP is still a bit unsightly at 1.42, he's successfully limited the damage to the tune of a 3.34 ERA over 12 starts spanning 64.2 innings. He's next slated to toe the rubber when Oakland makes the cross-country trip to take on the Mets in Queens.

Peterson did not factor into the decision in a loss to the Angels on Saturday, allowing two runs on five hits and one walk over six innings while striking out four.

EDGE Analysis

Peterson struggled a bit in the opening frame, issuing a walk to Zach Neto before giving up back-to-back singles with two outs, leading to a run coming across for the Angels. However, the lefty was able to pull himself together from that point on, allowing just one more run over his six innings of work while producing three 1-2-3 innings on the night. Peterson has now gone at least five innings in four consecutive starts and is yet to allow more than four runs in any outing this season. Saturday also marked the first time in his last five outings that he didn't walk multiple batters.
