Arrieta (10-11) took the loss against the Rockies on Thursday, allowing three earned runs, six hits and one walk over six innings while striking out three. Arrieta allowed all three runs in the first two frames, which included solo home runs off the bats of David Dahl and Trevor Story. He needed 103 pitches to get through six frames in what was likely his final appearance of 2018. Arrieta owns a 3.96 ERA (4.08 xFIP) with 138 strikeouts over 172.2 innings (31 starts) on the year.
Arrieta (10-10) took the loss Saturday, allowing four runs on four hits and three walks while striking out two over two innings against Atlanta. Arrieta (10-10), who has won just one game since the beginning of August, wasn't fooling the Braves, as he generated just four swinging strikes. The 32-year-old permitted two runs in each of the first two innings and did not come out for the third inning. Arrieta has a 3.94 ERA and a 1.29 WHIP, and he'll look to rebound Thursday in a tough matchup at Coors Field against the Rockies in what should be his final start of 2018.
Arrieta allowed four runs on nine hits and one walk while striking out six over five innings Monday against the Mets. He didn't factor into the decision. Arrieta struggled to find his groove in the series opener, giving up a run in the second inning followed by three in the fifth. His offense would bail him out by striking for four runs of their own in the fifth inning. The 32-year-old hasn't been sharp in September, surrendering 11 runs while punching out 24 through 17.1 frames. Arrieta will search for a better outcome in his next outing Saturday in Atlanta.
Arrieta gave up three runs on three hits and two walks across five innings during Game 2 of Tuesday's doubleheader against the Nationals. He recorded seven strikeouts and did not factor in the decision. Juan Soto's first-inning RBI double and fourth-inning two-run homer accounted for all the damage against Arrieta. The 32-year-old has a 3.66 ERA, 1.24 WHIP, and 127:52 K:BB over 159.2 innings this season, and is next expected to take the mound Monday against the Marlins.
Arrieta will start the second game of the Phillies' doubleheader Tuesday with the Nationals, Matt Gelb of The Athletic reports. Arrieta had been scheduled to toe the rubber Monday in the series opener, but he ended up being pushed back a day after that contest was postponed due to inclement weather. The change in the pitching schedule isn't expected to prevent Arrieta from picking up two starts this week, as he'll likely take the hill again Sunday versus the Marlins. Nick Pivetta, the Game 1 starter for Tuesday's twin bill, would also be a candidate to pitch in the series finale against Miami, but Arrieta's superior performance of late likely confers the elder statesmen the advantage for the two step.
