Spencer Arrighetti: Everything you need to know

Arrighetti (7-2) took the loss Sunday against the Royals, allowing four runs on eight hits and one walk while striking out seven over six innings. Sunday's outing was one of Arrighetti's roughest of the season, as the right-hander surrendered a season-high eight hits and the four runs allowed matched his season high. After limiting opponents to two or fewer earned runs in each of his first eight starts, he has now yielded three or more runs in three straight outings. The regression is surprising given his underlying metrics -- Arrighetti entered the start with a 29.5 percent hard-hit rate allowed, ranking in the 94th percentile among MLB pitchers. Despite the recent slide, he still owns an excellent 2.57 ERA, 1.22 WHIP and 60:32 K:BB across 63 innings. Arrighetti is scheduled to face Cleveland in his next start.

Arrighetti tossed six innings against the Angels on Monday, allowing three runs on four hits and four walks while striking out seven batters. It was a bit of a mixed bag for Arrighetti, as he issued four free passes and unfurled a wild pitch but also racked up 12 whiffs and seven punchouts. The right-hander held things down well outside of the second inning, which is when the Angels scored all three of their runs against him. Though those trio of earned runs marked the second-most Arrighetti has surrendered in an outing this season, he nonetheless finished with his fifth quality start of the campaign. Overall, Arrighetti has enjoyed an excellent season to this point, posting a 7-1 record along with a 2.21 ERA, 1.19 WHIP and 53:31 K:BB across 57 frames spanning 10 starts.

Arrighetti allowed four runs on six hits, a walk and a hit batsman while striking out three over four innings in a no-decision Wednesday versus the Pirates. Arrighetti ran into trouble in the fourth inning, serving up a grand slam to Henry Davis. This was the first bad outing of the season for Arrighetti -- he had gone at least five innings without allowing more than three runs in any of his first eight games. He's now at a 1.94 ERA, 1.18 WHIP and 46:27 K:BB through 51 innings this season. A 4.8 BB/9 suggests he's been very lucky so far, though it's a mark in line with his career norms. His next start is projected to be on the road versus the Angels.
