Spencer Arrighetti: Everything you need to know

Arrighetti (5-1) earned the win Friday against the Rangers after tossing 7.1 scoreless innings, allowing one hit and four walks while striking out five. Arrighetti's excellent start to the season reached a new high Friday, as he took a no-hitter into the eighth inning before having it broken up by a Justin Foscue single. Arrighetti has allowed one or fewer runs in all but one of his six outings since making his season debut April 15, and while he should experience some kind of regression sooner or later, it's impossible to overlook what he's been doing on the mound. Across six starts, Arrighetti owns a 1.50 ERA and a 1.19 WHIP over 36 innings with a 35:21 K:BB. The walks are concerning, as he's issued at least four free passes in four of his six starts.

Arrighetti (4-1) took the loss against the Reds on Saturday, allowing three runs (one earned) on five hits and three walks with five strikeouts over 5.2 innings. All of the damage against Arrighetti came in a three-run fifth inning, and he departed one out shy of a quality start at 93 pitches. The 26-year-old has yielded just one earned run in four of his five outings this season, though he's also issued at least three walks four times. He owns a 1.88 ERA, 1.33 WHIP and 30:17 K:BB across 28.2 innings and lines up for a home matchup against the Mariners next week.

Arrighetti (4-0) earned the win against the Red Sox on Saturday, allowing one run on five hits and five walks while striking out four across five innings. It was by no means a seamless outing for Arrighetti, who loaded the bases in both the third and fifth frames. However, he yielded just one run on a sacrifice fly from Willson Contreras in the fifth, and Arrighetti got enough run support to come away with his fourth victory of the season, which is tied for second-most in the American League. He'll bring a 1.96 ERA and 1.30 WHIP (across 23 innings) into his next start, tentatively slated for next weekend on the road against the Reds.
