Arrieta (5-6) was tagged with the loss Friday against the Padres after allowing six runs on six hits and two walks while fanning one across two innings.

EDGE Analysis

This was Arrieta's worst start of the season by a wide margin, as he needed 58 pitches just to complete the first two innings, gave up two homers and allowed six of the eight runs the Cubs allowed during the game. The veteran right-hander has given up four or more runs in three of his last six outings and owns an 8.28 ERA during that stretch, a span in which he's tossed more than five complete innings just once. The veteran will try to bounce back next week in a tough matchup on the road against the Padres.

Arrieta's ERA bumped up to 4.41 as he fell to 5-5 through 10 starts this season. He's projected to face the Giants on the road next weekend.

Arrieta dropped to 4-4 after giving up four earned runs on seven hits and two walks while striking out two over five innings in Wednesday's 4-3 loss to the Nationals.

EDGE Analysis

Arrieta kept the Nationals off the board for the first two innings, but things were bumpy thereafter. He allowed eight of the final 19 batters he faced to reach base, with Juan Soto's 421-foot solo shot off the Wrigley Field right-field scoreboard in the fifth inning ultimately holding up as the difference in the game. Since opening his second stint with the Cubs with a pair of quality starts, Arrieta has posted a 5.34 ERA, 1.25 WHIP and 6.5 K/9 over his subsequent six outings.

Arrieta (4-3) picked up the win Friday, allowing two runs on four hits and a walk over six innings in a 4-2 victory over the Tigers. He struck out one.

Both runs scored on solo shots by Jake Rogers and Robbie Grossman, but Arrieta otherwise held the Detroit offense in check. The veteran right-hander was making his first start since April 30 due to a thumb injury and was limited to 78 pitches (47 strikes), but he still came through with his fourth quality start of the year. He'll take a 4.10 ERA and 29:13 K:BB through 37.1 innings into his next outing.
